The #1 Asset to Keep Your PLC System Running

PLC System

Faulty memory, erratic behavior, difficulty finding replacements. No, we aren’t talking about the worst control ever. We’re describing your number one asset in keeping your operation running…. your people.

The great thing about PLCs is also the bad thing about PLCs: they are designed to run in harsh environments for a long time with little intervention.

The problem is that during those years, maintenance personnel can turn over 3 or 4 times.  Avoid a false sense of security by following the tips below and using your #1 asset.

In addition to keeping up with your maintenance and audit activities on the controls, give yourself the tools you need to be able to respond quickly and efficiently should a crisis arise.

Let’s face it, when the floor is down and everyone is waiting on you to get everything running again – that’s not the time to be searching around.

Maintain Your Brain with Training

Keep yourself up to date on GE 90-70 training.

Contact us to learn the latest on the hardware and software you run so you can stave off issues before they pop up.

And most of all, ensure that the new techs are trained not only in the technical side of maintaining your GE 90-70, but also in proper procedure and documentation.

We produce some training that we’re pretty proud of. You can find it:

Keep a Library of Knowledge

One of the most time-consuming parts of troubleshooting a system that’s having issues is tracking down where all the pieces are, and how they’re connected. This is especially true when bringing in someone to help.

Give yourself and your team a head start by keeping your library of assets up to date. They will be invaluable tools not only for troubleshooting, but also for getting new hires up to speed.

PLC System and LED Diagrams

Keep your system wiring diagrams updated and handy.  If you don’t have any, or they are old, you can update them as you go through and do your EMI audit.

If you bring in a technician to help troubleshoot or update your system, this is likely the first thing they will ask for. It’s also helpful to have if you need an extra pair of hands to help you track down a problem, and the only person available is Bob from Accounting.

Update system wiring diagrams that show what devices are connected to each input or output point on the PLC. This diagram should contain the electrical drawings of the system and everything that is connected to it, such as switches, lights, relays, etc. Once you know what is connected to each point on the PLC, you can use the LEDs on each module to determine which field device is failing or giving intermittent problems.

Here is an example:

90-70 LEDs

Store a copy in the cabinet for handy reference. Those LEDs are your best guide to a component that’s stopped working. They’re also the second thing an outside technician will ask for. Might as well have them ready.

Control Manuals

Have a copy of the manufacturer’s manual for each control on hand. We recommend having both a physical copy and a digital one. You can usually download a digital copy from the manufacturer’s website. If you have a tablet, you can keep the digital copies with you on the floor.

Advanced Knowledge

We hope you’ve found a few tips to help you improve your PM process and eliminate some headaches with your GE 90-70 system – especially in those stressful times when something does go wrong.
