Ensuring accurate pigment dispensing.

20/06/2018

PD Edenhall Ltd is one of the largest independent concrete facing brick manufacturers in Britain. They needed to accurately monitor the quantity of pigment being dispensed into the weigh hopper throughout the manufacture of concrete facing bricks.

Precise pigment dispensing needs to be calculated as inaccurate amounts of pigment can lead to incorrect colour blends, resulting in a loss of sales and profit.

Solution – Accurate DBBSM S-Beam Load Cells and Intuitive4-L Digital Indicator
To monitor the quantity of pigment going into the blend, 3x DBBSM S-beam load cells were connected together to the supports of the pigment weigh hopper.  The DBBSM S-beam load cells checked the load of the pigment weigh hopper throughout the pigment dispensing process and the outputs of the load cells were sent to an Intuitive4 load cell digital indicator.  This enabled the engineers to constantly check the correct amount of pigment was being dispensed into the mix.

“We chose Applied Measurements’ DBBSM s-beam load cells as the pigment is £1000 per tonne so has to be extremely accurate.” Paul Akers, Works Manager at PD Edenhall Ltd told us.

DBBSM S-Beam Load Cells

  • Capacities: 0-1kg up to 0-30,000kg
  • Force & Load Measuring
  • Tension & Compression
  • Output: 2mV/V to 2.7mV/V
  • High Accuracy: <±0.03% Rated Capacity
  • Custom Versions Available
  • Fast and Simple to Install

The DBBSM S-beam load cells were ideal to use in this application as they are extremely accurate of better than ±0.03% of the rated capacity.  Coupled with their dual bending beam design, they guarantee excellent accuracy.  Improved accuracy can be further guaranteed by using our specially designed rod end bearings to help reduce any extraneous forces.

They offer an optional sealing to provide protection in the dusty environment and a robust 4-core polyurethane cable, making them ideal to use in the pigment dispensing machine.

Intuitive4-L Load Cell Digital Indicator

  • 6-Digit LED Display (±199999)
  • Modular Construction
  • Fast & Simple to Setup
  • Ideal for Harsh Environments – Dust Tight IP65 Protection (Once Installed)
  • Superior Accuracy – 10 Point Linearisation
  • Higher Stability – Signal Filtering Adjustment
  • Improved Resolution – 20-bit A/D Converter
  • Compatible with the INT2 Series
  • 10Vdc Load Cell Excitation @ 120mA max.
  • Powers up to 4x 350Ω Load Cells
  • Available in Less Than 1 Week

The Intuitive4-L load cell digital indicator was chosen for this application as superior accuracy was needed due to the high cost of the yellow pigment.  The intuitive4-L boasts a 10 point linearisation guaranteeing outstanding accuracy coupled with a 20-bit A/D converter for high resolution.  High stability is promised with signal filtering adjustment options which reduce the effect of noise or instability of the input signal.  Plus, it benefits from an active filter which reduces the effects of vibration and other external sources of system noise.

The intuitive4-L load cell digital indicator is fast and simple to setup with its single layer menu making the options easier to find.  Dimensions and fittings are entirely compatible with the existing Intuitive2 models making the switch over to this new improved version even easier.

Once installed the intuitive4-L load cell digital indicator has an IP65 dust tight protection rating making it ideal to use in this harsh construction environment.  If that’s not enough we can also provide an optional waterproof front panel cover for that extra level of protection.

The intuitive4-L digital panel meter has a modular construction meaning that PD Edenhall Ltd could configure it to their exact specification saving them money.  Options available include voltage or current analogue outputs, 2 or 4 alarm relays and a serial data output in one of several formats including RS232 ASCII, RS485 ASCII and RS485 ModBus RTU, making this a truly flexible load cell digital indicator.

The world of virtual commissioning.

15/06/2018
Robert Glass, global food and beverage communications manager at ABB explores the concept of virtual commissioning and how system testing can benefit the food industry.

In 1895, pioneer of astronautic theory, Konstantin Tsiolkovsky, developed the concept of the space elevator, a transportation system that would allow vehicles to travel along a cable from the Earth’s surface directly into space. While early incarnations have proven unsuccessful, scientists are still virtually testing new concepts.

Industry 4.0 continues to open up new opportunities across food and beverage manufacturing. In particular, these technologies help improve manufacturing flexibility and the speed and cost at which manufacturers are able to adapt their production to new product variations. Virtual commissioning is one of these key technologies.

What is virtual commissioning?
Virtual commissioning is the creation of a digital replica of a physical manufacturing environment. For example, a robotic picking and packing cell can be modeled on a computer, along with its automation control systems, which include robotic control systems, PLCs, variable speed drives, motors, and even safety products. This “virtual” model of the robot cell can be modified according to the new process requirements and product specifications. Once the model is programmed, every step of that cell’s operation can be tested and verified in the virtual world. If there are changes that are needed in the process automation or robot movement, these can be made on the same computer, allowing the robot to be reprogrammed, orchanges made to the variable speed drives and PLC programming. The ABB Ability™ RobotStudio is one tool that enables this type of virtual commissioning.

Once reprogrammed, the system is tested again and if it passes, it’s ready for physical deployment. This is where the real benefits become tangible. By using virtual commissioning to program and test ahead of time, less process downtime is required and manufacturers can reduce the changeover risks.

Automation programming and software errors in a system can be incredibly difficult and costly to rectify, particularly if they are found later on in the production process. Research by Austrian software testing frim Tricentis, estimated that software bugs, glitches and security failures cost businesses across the world $1.1 trillion.

To achieve the full potential of virtual commissioning, the simulation must be integrated across the entire plant process, including both the planning and engineering phase. Known as simulation-based engineering, this step is integral for the installation of reliable systems. The use of simulations in a plant is not a new concept, in fact virtual commissioning has been researched for more than a decade.

The benefits
The implementation of virtual commissioning brings with it a number of benefits. The ‘try before you buy’ concept allows plant managers to model and test the behavior of a line before making any physical changes. This saves time as the user can program the system’s automation while testing and fixing errors. The use of a digital model can also reduce risk when changing or adding processes.

One company which has seen significant improvements in production since investing in virtual commissioning is Comau, a supplier of automotive body and powertrain manufacturing and assembly technologies. Comau’s head of engineering and automation systems, Franceso Matergia, said: “We were able to reprogram 200 robots in just three days using virtual commissioning as opposed to roughly 10 weekends had the work been done on the factory floor.”

Just as you wouldn’t build a space elevator without meticulous planning and years of small scale prototyping, it’s very cost and time beneficial to build and test in a virtual environment where you can find the bugs and discover the unforeseen challenges and mitigate them without added downtime or loss of production. It’s much better to discover that bug while on the ground versus at 100,000 feet midway between the surface of the earth and that penthouse in space.

Monitoring and managing the unpredictable.

07/06/2018
Energy sector investments in big data technologies have exploded. In fact, according to a study by BDO, the industry’s expenditure on this technology in 2017 has increased by ten times compared to the previous year, with the firm attributing much of this growth to the need for improved management of renewables. Here, Alan Binning, Regional Sales Manager at Copa-Data UK, explores three common issues for renewables — managing demand, combining distributed systems and reporting.

Renewables are set to be the fastest-growing source of electrical energy generation in the next five years. However, this diversification of energy sources creates a challenge for existing infrastructure and systems. One of the most notable changes is the switch from reliable to fluctuating power.

Implementing energy storage
Traditional fossil-fuel plants operate at a pre-mitigated level, they provide a consistent and predictable amount of electricity. Renewables, on the other hand, are a much more unreliable source. For example, energy output from a solar farm can drop without warning due to clouds obscuring sunlight from the panels. Similarly, wind speeds cannot be reliably forecasted. To prepare for this fluctuation in advance, research and investment into energy storage systems are on the rise.

For example, wind power ramp events are a major challenge. Therefore, developing energy storage mechanisms is essential. The grid may not always be able to absorb excess wind power created by an unexpected windspeed increase. Ramp control applications allow the turbine to store this extra power in the battery instead. When combined with reliable live data, these systems can develop informed models for intelligent distribution.

Britain has recently become home to one of the largest energy storage projects to use EV batteries. While it is not the first-time car batteries have been used for renewable power, the Pen y Cymoedd wind farm in Wales has connected a total of 500 BMW i3 batteries to store excess power.

Combining distributed systems
Control software is the obvious solution to better monitor this fluctuating source of power. However, many renewable energy generation sites, like solar PV and wind farms, are distributed across a wide geographical scope and are therefore more difficult to manage without sophisticated software.

Consider offshore wind farms as an example. The world’s soon-to-be-largest offshore wind farm is currently under construction 74.5 miles off the Yorkshire coastline. To accurately manage these vast generation sites, the data from each asset needs to be combined into a singular entity.

This software should be able to combine many items of distributed equipment, whether that’s an entire wind park or several different forms of renewable energy sources, into one system to provide a complete visualisation of the grid.

Operators could go one step further, by overlaying geographical information systems (GIS) data into the software. This could provide a map-style view of renewable energy parks or even the entire generation asset base, allowing operators to zoom on the map to reveal greater levels of detail. This provides a full, functional map enabling organisations to make better informed decisions.

Reporting on renewables
Controlling and monitoring renewable energy is the first step to better grid management. However, it is what energy companies do with the data generated from this equipment that will truly provide value. This is where reporting is necessary.

Software for renewable energy should be able to visualise data in an understandable manner so that operators can see the types of data they truly care about. For example, wind farm owners tend to be investors and therefore generating profit is a key consideration. In this instance, the report should compare the output of a turbine and its associated profit to better inform the operator of its financial performance.

Using intelligent software, like zenon Analyzer, operators can generate a range of reports about any information they would like to assess — and the criteria can differ massively depending on the application and the objectives of the operator. Reporting can range from a basic table of outputs, to a much more sophisticated report that includes the site’s performance against certain key performance indicators (KPIs) and predictive analytics. These reports can be generated from archived or live operational data, allowing long term trends to be recognised as well as being able to react quickly to maximise efficiency of operation.

As investments in renewable energy generation continue to increase, the need for big data technologies to manage these sites will also continue to grow. Managing these volatile energy sources is still a relatively new challenge. However, with the correct software to combine the data from these sites and report on their operation, energy companies will reap the rewards of these increasingly popular energy sources.


Challenges facing energy industry sector.

21/05/2018

Leaders from Britain’s  energy industry attended Copa Data’s  zenon Energy Day 2018 at the Thames Valley Microsoft centre. The event, which was held on in April 2018, welcomed industry experts and energy suppliers to address the current challenges the sector is facing — renewable generation, substation automation, IoT and cyber security.

scamaill

A welcome speech from the British MD od Copa Data , Martyn Williams, started a day encompassed a series of talks from industry experts. Speakers included Ian Banham, IoT Technical Sales Lead UK for Microsoft, Chris Dormer of systems integrator, Capula and Jürgen Resch, Copa Data Energy Industry Manager.

Preparing for renewables
Only 24 per cent of Britain’s electricity comes from renewable sources — a relatively low figure compared to some European countries.  However, the percentage is growing. In 2000, Britain’s renewable capacity was 3,000 MW, and rose eleven-fold by the end of 2016 to 33,000 MW.

To prepare for the impending challenges for this market, Jürgen Resch’s presentation discussed how software can alleviate some of the common questions associated with renewable energy generation, including the growing demand for energy storage.
“Energy storage is often used in combination with renewables because renewable energy is volatile and fluctuating,” explained Resch. “In Korea, the government is pumping $5 billion dollars into energy storage systems. In fact, every new building that is built in Korea gets an energy storage battery fitted into the basement.”

BMW’s battery storage farm in Leipzig (D) was also presented as an example. The facility, which uses COPA-DATA’s zenon as the main control centre system, uses 700 high-capacity used battery packs from BMW i3s and could also provide storage capacity for local wind energy generation.

Moving onto specific issued related to wind generation, Resch discussed the potential challenge of reporting in a sector reliant on unpredictable energy sources.
“Reports are particularly important in the wind power industry,” he said. “Typically, owners of wind farms are investors and they want to see profits. Using software, like zenon Analyzer, operators can generate operational reports.

“These reports range from a basic table with the wind speeds, output of a turbine and its associated profit, or a more sophisticated report with an indication of the turbines performance against specific key performance indicators (KPIs).”

Best practice for substation automation
Following the morning’s keynote speeches on renewable energy, Chris Dormer of Capula, presented the audience with a real-life case study. The speech discussed how smart automation helped to address significant issues related to the critical assets of the National Grid’s substations, where Capula was contracted to refurbish the existing substation control system at New Cross.

substn“Like a lot of companies that have developed, grown and acquired assets over the years, energy providers tend to end up with a mass mixture of different types of technology, legacy equipment and various ways to handling data,” explained Dormer. “For projects like this, the first key evaluation factor is choosing control software with legacy communication. We need to ensure the software can talk to both old legacy equipment in substations as well as modern protocol communications, whilst also ensuring it was scalable and compliant.

“The National Grid will make large investments into IEC 61850 compatible equipment, therefore for this project, we needed an IEC 61850 solution. Any system we put in, we want to support it for the next 25 years. Everyone is talking about digital substations right now, but there are not that many of them out there. That said, we need to prepare and be ready.”

The case study, which was a collaborative project with COPA-DATA, was recognised at the UK Energy Innovation Awards 2017, where it was awarded the Best Innovation Contributing to Quality and Reliability of Electricity Supply.

“Our collaboration with COPA-DATA allows us to address modern energy challenges,” explained Mark Hardy, Managing Director of Capula upon winning the award last year. “It helps drive through the best value for energy customers.”

Cyber security – benefit or burden?
“Raise your hand if you consider cyber security to be a benefit?” Mark Clemens, Technical Product Manager at Copa Data asked the audience during his keynote speech on cyber security. “Now, raise your hand if you consider it to be a burden?”

substn2Clemens’ question provided interesting results. Numerous attendees kept their hands raised for both questions, giving an insight into the perception of cyber security for those operating in the energy industry — a necessary evil.

“A cyber-attack on our current infrastructure could be easy to execute,” continued Clemens. “95 per cent of communication protocols in automation systems don’t provide any security features. For those that do provide security, the mechanisms are often simply bolted-on.”

Clemens continued to explain how substation design can strengthen the security of these sites. He suggested that, despite living in the era of IoT, energy companies should limit the communication between devices to only those that are necessary. The first step he suggested was to establish a list of assets, including any temporary assets like vendor connections and portable devices.

“There are lots of entry points into a substation, not only through the firewall but through vendors and suppliers too. This doesn’t have to be intentional but could be the result of a mistake. For example, if an engineer is working in the substation and believe they are testing in simulation mode, but they are not, it could cause detrimental problems.”

Collaborating with Microsoft
The address of Microsoft’s UK IoT Technical Sales Lead, Ian Banham focused on the potential of cloud usage for energy companies. When asking attendees who had already invested in cloud usage, or planned on doing so, the audience proved to be a 50:50 split of cloud enthusiasts and sceptics.

“IoT is nothing new,” stated Ian Banham, IoT Technical Sales Lead at Microsoft. “There’s plenty of kit that does IoT that is over 20 years old, it just wasn’t called IoT then. That said, there’s not a great deal of value in simply gathering data, you’ve got to do something with that data to realise the value from it.

“The change in IoT is the way the technology has developed. That’s why we are encouraging our customers to work with companies like COPA-DATA. They have done the hard work for you because they have been through the process before.”

He explained how Microsoft’s cloud platform, Azure, could be integrated with COPA-DATA’s automation software, zenon. In fact, COPA-DATA’s partnership with Microsoft is award-winning, COPA-DATA having won Microsoft Partner of the Year in the IoT category in 2017.

How the field service management sector is being changed by IoT

George Walker, managing director Novotek, explains how the Internet of Things (IoT) is changing field service. As more companies move to a predictive model of equipment maintenance, they are looking for ways to use connected devices to improve field service.

Before internet-connected devices were the norm, it was common for facilities managers and in-house maintenance staff to spend time on the phone with suppliers booking in a suitable time for repairs to be carried out. It might have taken hours, if not days, for an engineer to come out to the site — leading to potential downtime in the interim.

When the technician came to the site, they may have found that they didn’t have the right tools, the right parts, or even the specific knowledge to carry out the service needed. This would mean the same technician would have to go back, or a second technician would need to come out to complete the service.

Although this model has been the norm for many years, it is no longer feasible in a modern environment. Factors such as first-time fix rates, mean time to repair and overall efficiency are driving businesses to closely monitor resource allocation and the time spent on maintenance.

Field service management has traditionally been responsible for activities such as locating fleet vehicles, scheduling maintenance work-orders and dispatching personnel. However, the advent of the IoT means that much of this model is shifting to real-time, predictive maintenance and those companies that adapt their businesses will benefit the most from the resulting competitive advantage.

The number of connected IoT devices is set to surge in the next few years, going from 27 billion in 2017 to an estimated 125 billion in 2030, according to analysis firm IHS Markit. Sensors can not only help engineers to remotely diagnose problems in many instances, they can also help to remotely repair or prevent further damage to equipment.

However, hardware sensors are just the start. Better software will help businesses to truly realise the potential of IoT in field service management. Modern field servicing software needs to go beyond the basics and offer better wider integration with the company’s inventory, billing and enterprise resource planning (ERP) systems.

This is why we’ve partnered with the leading vendor in the industry to help our customers achieve better results. Novotek is the sole distributor of GE’s ServiceMax field servicing software in Britain and Ireland. ServiceMax creates solutions for the people who install, maintain and repair machines across dozens of industries, as the leading provider of complete end-to-end mobile and cloud-based technology.

The results speak for themselves. In a recent survey of ServiceMax customers in March 2018, technicians and engineers were 19 per cent more productive, service costs went down by 9 per cent and service revenue increased by 10 per cent. In addition to this, customers saw contract renewals increase by 11 per cent, mean time-to-repair decrease 13 per cent and equipment uptime improve by 9 per cent — leading to customers being 11 per cent more satisfied. Overall, compliance incidents dropped by 13 per cent.

By sending the right technician to the right job, at the right time, you avoid situations where some technicians are overloaded, while others have white space in their schedules. Using an app that works across devices, technicians can request jobs from anywhere. Each service level agreement (SLA) is easily managed and field service reports are easily produced.

What was science fiction a mere five years ago is now reality. A machine on a customer site can send an alert to the service team warning them of an imminent failure and potential downtime. Technicians can then be proactively dispatched to site with the right parts to carry out urgent repairs and mitigate costly downtime.

IoT has already drastically changed other sectors of the industrial landscape and is now making waves in the field service management sector. Whether you’re a utility business, a healthcare provider or even a telecoms business, it’s about time you looked at how IoT will change field servicing for you.

Keep making the tablets!

08/05/2018
This article shows how valuable manufacturing production line downtime in the pharmaceutical industry can be reduced by ensuring predictive maintenance of tablet making machinery using Harting’s MICA industrial computing platform.

Introduction
Harting recently challenged postgraduate students from the Centre for Doctoral Training in Embedded Intelligence at Loughborough University to investigate practical application solutions where MICA – the company’s innovative open platform based ruggedised industrial edge computing device – could be applied to the benefit of manufacturing. Simple seamless integration within existing established production processes was the target, based on the concept of machine predictive maintenance.

The key objective was to achieve immediate productivity improvements and return on investment (RoI), thus satisfying the increasing trend for Integrated Industry 4.0 implementation on the factory floor. One such proposal was suggested for volume manufacturers in the pharmaceutical industry: in particular, those companies manufacturing tablets using automated presses and punch tools.

Data from these machines can be collected using passive UHF RFID “on metal” transponders which can be retrofitted to existing tablet press machines and mounted on the actual press-die/punch tools. The RFID read and write tags can record the pressing process, i.e. the number of operations performed by a particular press die, plus any other critical operating sensor-monitored conditions. The system can then review that data against expected normal end-of-life projected limits set for that die.

Such data can be managed and processed through Harting’s MICA edge computing device, which can then automatically alert the machine operator that maintenance needs to take place to replace a particular die-set before it creates a catastrophic tool failure condition and breakdown in the production line – which unfortunately is still quite a common occurrence.

Open system software
MICA is easy to use, with a touch-optimised interface for end users and administrators implemented entirely in HTML5 and JavaScript. It provides an open system software environment that allows developers from both the production and IT worlds to quickly implement and customise projects without any special tools. Applications are executed in their own Linux-based containers, which contain all the necessary libraries and drivers. This means that package dependencies and incompatibilities are eliminated. In addition, such containers run in individual “sandboxes” which isolate and secure different applications from one another with their own separate log-in and IP addresses. As a result, there should be no concerns over data security when MICA is allowed access to a higher-level production ERP network.

MICA is already offered with a number of containers such as Java, Python C/C++, OPC-UA, databases and web toolkits, all available on free download via the HARTING web site. As a result, users should be able to download links to the operating software system compatible with an existing machine, enabling full 2-way communication with the MICA device. Relaying such manufacturing information, which can comprise many gigabytes of data in the course of a day, directly to the ERP would normally overwhelm both the network and the ERP. With the MICA, this data stream is buffered directly onto the machine and can be reduced to just essential business-critical data using proven tools from the IT world.

The resultant improvements in productivity include:

– Less downtime reduces the amount of money lost during unforeseen maintenance of damaged punch tools.
– Individual punch identification will help in removing a specific punch, once it has reached its pre-set operational frequency working limit.
– A digital log of each punch and the number of tablets that it has produced is recorded. This provides vital information for GMP (Good Manufacturing Practice) regulators such as the MHRA (Medicines & Healthcare products Regulatory Agency) or the FDA (Food & Drug Administration).

A further benefit is that MICA is very compact, with DIN rail mounting fixing options that allow it to be easily accommodated inside a machine’s main control cabinet.

Load cells on stage!

30/04/2018
With theatres striving to create breath-taking spectacles and leave the audience gasping for more, there is often world-class engineering behind the scenes. Sensor Technology is developing technology to ensure safety when excited performers and heavy machinery share the same space.

If live theatre is to compete with film and television, it has to produce visual spectacles to complement the performance of the actors, singers and musicians on stage. Hollywood’s increasing reliance on CGI (computer generated imagery) has upped the ante for stage set designers, who have to work before a live audience, in restricted space and with a constant eye on the safety of the many people working frantically round the set.

Many stage props and almost all of the backdrops are lowered onto the stage from the fly tower just behind it. Usually this is done quickly between scenes, but sometimes it is during – and as part of – the actual performance. Either way, safety and reliability are essential.

“Until recently, the sets were manually controlled with a technical stage manager watching everything from the wings and giving instructions by radio to the winch operators above.” explains Tony Ingham of Sensor Technology who is helping to introduce safety systems and automation to the theatre industry.

“Speed is of the essence during scene changes, but you have to be confident the winches won’t fail – which could easily damage the set or injure a person.”

Sensor Technology is achieving this using real-time load signals from each winch. The data is monitored by a computer in the control room so that instant action can be taken if any loads move out of tolerance.

“We developed the load cells, which we have called LoadSense, a couple of years ago, originally for monitoring cargo nets carried under helicopters.” says Tony. “We were asked to develop one specific capability within the cell and were delighted to do so because we could see that the technology would transfer to many other fields – although I didn’t realise it would get to be a backstage pass to a world of greasepaint and legwarmers!”

That critical characteristic was robust, industrial-grade wireless communications, something in which Sensor Technology already has a 15 year track record from its TorqSense transducer range. In basic terms, each LoadSense has an on-board radio frequency transmitter which sends signals to the control room computer. The transmitter has to be physically robust to cope with the environment it finds itself in and capable of maintaining its signal integrity through the most corrupting of harmonic conditions.

“By working in real time, we can act instantly to any problems. For instance, if a load starts running too fast we would slow it down immediately. If a prop is heavier than expected this could suggest someone was standing on it so shouldn’t be whizzed 50 feet into the air at high speed. In fact, in this case, the computer ‘jiggles’ the load for a second or two as a warning to encourage the person to step away: If the load then returns to normal we are happy to let it rise; if it doesn’t, the floor manager is alerted by an alarm to check the situation.”

LoadSense is proving so sensitive that it can provide a feedback signal to close the control loop on a vector drive controlling the winch. Normally theatre engineers use sensorless vector drives, which offer good dynamic performance without the complications of wiring in a feedback sensor.

Sensor Technology is closing the loop which improves system integrity and enhances safety by a significant margin.

“Not that many years ago, stage scenery was fairly static, being moved only during the interval when the curtains were closed,” Tony recalls. “Then the big theatres in the West End and on Broadway started to emulate some of the things you see in the movies. Looking back, those early efforts were pretty crude, but you would say the same about long-running film franchises such as James Bond or Indiana Jones. “Nowadays, film directors can produce their spectacular images using CGI, and this has upped the ante no end for their cousins in live theatre. The computer power they turn to is not virtual reality but industrial automation.”

In fact, theatre engineers probably work in more demanding conditions than manufacturing engineers. Everything has to be right on the night, harmonic corruption is at stratospheric levels, there can be major changes at a moments notice, people run through the ‘machinery’ without a thought for personal safety.

“But with automation some order is brought to this creative chaos. In fact, the health and safety inspectors now insist on it, with lots of failsafes and feedbacks. I honestly don’t think theatre engineers would be able to achieve half of what they do without wireless communications. There would be just too many wires running all over the place and inevitably some would get broken at the most inopportune of moments.”
