Your Legacy Equipment Can Still Get You to Digital Transformation

Within the creep toward digital transformation and Trade 4.0, the highlight usually falls on ravishing machines, Internet of Things (IoT) sensors, and fully automatic production lines. However for many manufacturers, the true fable entails diverse older, fight-tested equipment restful working solid on the shop floor.

“Rip and exchange” is a phrase no manufacturer desires to hear, nonetheless that’s the phrase that many managers apprehension as soon as they judge taking the foremost step in the digital transformation gallop. So much of the legacy machines or assist watch over programs, in spite of every thing, had been built sooner than digital networking, true-time data integration, and cloud connectivity grew to turn out to be identical outdated. These programs might maybe lack built-in sensors, Ethernet ports, or programmable good judgment controllers (PLCs) with start conversation requirements.

Alternatively, these programs continue to fetch core manufacturing obligations with precision and reliability. In lots of cases, they listing a long time of capital investment and operational ride.

Horror no longer. Removed from being a barrier, these legacy programs can turn out to be mandatory constructing blocks of a ravishing, associated manufacturing ambiance. Though more fresh equipment is designed with digital integration in mind, legacy machines can restful play a severe role — particularly when label, continuity, and ROI are factored in. With the magnificent methodology, manufacturers don’t settle on to make a option from growth and practicality.

Reap the Advantages of Orderly Upgrades

In desire to ripping out and changing functional legacy programs, manufacturers can retrofit them with ravishing technologies, similar to edge computing devices, aftermarket sensors, and industrial conversation gateways. The result? Proper-time data take hold of, improved productiveness, and visibility into operations — all with out ranging from scratch.

There are classes to be learned alongside the methodology, nonetheless one in every of potentially the most important is that you might maybe seemingly be kicking yourself for no longer doing it sooner. “We’ve got prospects that wait and wait and wait,” notes T.J. Tatum, senior construct engineer for Bosch Rexroth. “However as soon as they in the end make investments and at final construct it, I usually web: ‘Wow. We must occupy performed that a really long time ago.’”

No longer handiest can you extend the invaluable lifetime of your assets, nonetheless the advantages of digital transformation are furthermore substantial.

By integrating sensors, edge devices, and connectivity modules, manufacturers can web admission to true-time operational data from machines that previously operated in isolation. This visibility allows for predictive maintenance, reduced downtime, and optimized performance — boosting every productiveness and total equipment effectiveness (OEE).

These upgrades furthermore fetch a bridge between the venerable and the novel, enabling legacy machines to talk with glossy manufacturing execution machine (MES), enterprise helpful resource planning (ERP), or cloud platforms. This integration helps smarter resolution-making and centralized assist watch over, accelerating the shift toward Trade 4.0.

In addition as, retrofitting helps manufacturers meet sustainability targets by lowering shatter, lowering energy consumption, and avoiding the environmental label of untimely equipment replacement. For many, it’s the fastest and most ambiance pleasant path to a smarter, more associated, and more resilient manufacturing operation.

Add-ons That Benefit

There’s no settle on to start from scratch. “You’ve got machines that work that construct your process. We factual settle on to computer screen some capabilities on that machine — whether it’s motor present, vibration, seemingly rigidity, some various stages,” Tatum says. “I will usually construct that by looking out to search out a smaller controller and tying into your present controls on the machine.”

If the machine has a minimal of some web of Modbus serial communications, that is on the total easy. If the equipment’s older than that, discrete I/O shall be used to connect to a subsequent-generation controller to enhance Trade 4.0 requirements.

“So don’t rip out the total controls; let’s factual tie into the foremost capabilities that we settle on to survey,” Tatum adds.

What exactly you wish for your machine will fluctuate broadly reckoning on what you’ve already got on it. For occasion, Tatum capabilities to Bosch Rexroth’s Assembly Technology division, the set up the company makes conveyors.

“All those conveyors — whether to procure it as of late or to procure it 30 years ago — it’s got an induction equipment motor on there. I will use some CTs [current transformers] to measure motor present coming assist in and construct some predictive maintenance off that,” Tatum explains. “I will furthermore use some vibration sensors placed in the magnificent areas on there and construct some bearing prognosis, and I will predict set up on and trot on the bearings.”

Adding two various styles of sensors to the equipment, on this case, adds a particular stage of complexity. “The older machine might maybe furthermore or might maybe furthermore no longer accumulate that complex of a sensor, so I bring in a smaller IoT-ready controller,” Tatum says.

This more or much less addition to your equipment might maybe label as limited as a pair thousand bucks, Tatum notes, or it is going to label as phenomenal as $10,000 to $20,000. “It is going to rely on the amount of sensors and how phenomenal data you ought to preserve,” he says.

About a of the components affecting label and complexity include whether you’re storing the guidelines regionally or in the cloud — and every thing that resolution entails. “If you happen to’re storing it up in the cloud, then there’s usually some habitual costs on that,” Tatum says. “And now you wish a controller that no longer handiest can connect to the Internet nonetheless furthermore has firewalls and VPN in set up to manufacture it a trusty connection.”

An App-Primarily based System to Trade 4.0

On the heart of the CtrlX platform is a versatile, app-basically based controller which might be adapted to satisfy various industrial desires. “We’ve got a controller on there similar to a PLC, nonetheless it’s an app-basically based controller,” Tatum explains. “So if I need it to be a PLC, I set up a PLC app on it and I will write ladder good judgment, structured textual hiss material, whichever. On this case, I need it to be an IoT machine, so I’m going to position an IoT app on it.”

The app being used on this case is is known as Tool Bridge, which allows the controller to talk all the device by a colossal sequence of fashioned industrial protocols. Once the connection is established, data shall be pulled into the CtrlX controller.

The instance in Decide 1 uses Modbus TCP/IP to drag data from one controller, and a Siemens S7 connection to retrieve data from but one more. That data is then fed into a MongoDB database. For visualization, a Node-RED front close is used to label the implications in true time.

In a roundabout device, the CtrlX platform acts as a bridge between legacy and glossy industrial programs. “I’m the use of this Tool Bridge app to drag that data from that legacy equipment onto our controller,” Tatum says. “From there, I will send it up into the cloud or I will assist all of it regionally.”

PIA Automation takes a the same methodology with its PIA Industrial App Suite (piaIAS), a digital portfolio of merchandise, solutions, and companies and products used to commission and optimize the machines that it designs. “However these apps can furthermore be utilized retroactively,” explains Thomas Schwoerer, managing director at PIA Automation, which builds machines for assembly and sorting out.

The ravishing apps combine energetic and passive substances, Schwoerer notes, to fetch a vary of capabilities. “For instance, we occupy a allotment known as piaOEEtracker, which will improve availability,” he says. “Now we occupy an app known as piaAnalyze that is for quality improvements. Now we occupy one known as piaOptimum that is to enhance efficiency.”

Varied modules include piaVisibility and piaMaintenance. The instruments tackle various person groups with substances providing data for line workers, stories for shift managers and the maintenance personnel, or reports for administration.

“We use these if we produce a stamp-novel machine,” Schwoerer says. “And we’d furthermore use the identical instruments if we retrofit an present venerable machine.”

Digital Twins Benefit to Optimize Production

When PIA Automation designs a brand novel custom-made machine from scratch, it furthermore builds a digital twin round that machine — modeling and simulating the motion mechanics, throughput, and heaps others., of the machine. “We program the code even sooner than the foremost screw is on the shop floor,” Schwoerer says.

That identical digital twin technique shall be utilized to legacy programs — to reverse engineer the bodily machine assist into the digital world, Schwoerer explains. “Surely one of our entities currently has the kind of query on the desk to reverse engineer a machine that used to be no longer even built by PIA,” he notes. PIA is working to digitalize the third-party equipment to serve optimize its performance.

Making a digital twin of a legacy machine shall be particularly life like if the aim is to optimize throughput. A customer might maybe narrate, shall we narrate, that they’re taking a peep to enhance cycle time by 20% and even 50%, and sweetness if their venerable machine shall be retrofitted to construct that. “That’s the set up the digital twin world comes in and has more capacity,” Schwoerer says.

Here’s actually the query that came no longer too long ago from a tier one automotive dealer. They had an venerable machine built by a company that has since long gone out of industry. They settle on to preserve the use of the machine while furthermore enhancing cycle time and throughput.

On this case, the customer had a CAD model on hand to serve PIA Automation bring the legacy machine into the digital world. This undoubtedly helps, providing a injurious from which to start. However PIA can furthermore use a handheld software program, walking round a machine to manufacture some extent cloud and reverse engineer the machine from there.

How Weak Is Too Weak?

No longer every legacy machine shall be a candidate for the advantages of a digital twin, Schwoerer concedes. “It would count on the complexity and the job that the machine is focused for,” he says.

From Bosch Rexroth’s standpoint, no equipment is simply too venerable to bring into the digital realm.

“My background used to be in self-discipline carrier, so we labored on diverse the venerable equipment, and among the stuff used to be sooner than the PLCs had been even set up in,” Tatum says. “I opened a cupboard as soon as and there’s factual a bunch of relays in there, so the total thing used to be performed in relay good judgment. However even those styles of programs — I will bring those into a controller, and I will analyze that data.”

Granted, it obtained’t be particularly refined data on this case, nonetheless reckoning on the application, that stage of prognosis might maybe be ample.

Classes Learned: Don’t Fetch Buried in Recordsdata

One label of caution Tatum mentions to manufacturers all in favour of bringing their venerable programs into the stylish world: Beware what number of data capabilities you lag after.

Manufacturers usually underestimate the amount of data they are inclined to procure as soon as they connect legacy programs, Tatum says. “They connect to an venerable machine and they also settle on to bring in every point of data seemingly, and they also web overwhelmed with the amount of data they raise in.”

Bringing in 15,000 variables factual due to you shall be ready to isn’t repeatedly potentially the most entertaining route. As but one more, Tatum advises, manufacture particular you perceive the severe capabilities of the machine after which bring in factual a handful of variables that you ought to preserve an survey on.

“You don’t need every ingredient of the machine due to you’re going to web overwhelmed by the guidelines,” he says. “So shatter it down and perceive the machine itself. What is severe to that machine working? What construct you ought to computer screen? Are you looking out to computer screen OEE? Are you looking out to search out predictive maintenance? Enjoy a scope of what you’re looking out to search out. In any other case, you’ll bring in methodology too phenomenal data.”

Varied advice that Tatum presents is to start cramped. “You don’t occupy to manufacture it substantial essential. Birth with a few key capabilities on that machine — seemingly you ought to computer screen amperage and rigidity,” he says. “Probabilities are you’ll be ready to rob a dead methodology into it. You don’t occupy to construct it impulsively.”

Legacy equipment doesn’t settle on to be a roadblock to digital transformation — truly, it’ll be a key enabler. With the magnificent mixture of ravishing sensors, edge controllers, and trusty connectivity, manufacturers can bridge the gap between analog reliability and digital intelligence.

Retrofitting older machines allows for important data sequence, true-time visibility, and operational improvements with out the disruption or label of pudgy machine replacement.
