VIPA PLC - Faulty 32bit Output Module


I'm so happy to see a green run LED on this PLC on a customer’s wash plant after seeing a red SF LED for the last few hours.

This VIPA PLC looks like a Siemens CPU, acts like a Siemens PLC and even works with Siemens S7 software, but it isn’t Siemens!

Luckily, using S7 and a Simatic Field PG a faulty 32-bit output module was found to be causing the error and throwing it into Stop.

Once they were replaced, we had them back up and running.

We have the software, hardware, tools, equipment and knowledge to interrogate, diagnose, modify and repair anything with Siemens S7 PLC’s.

Please contact Control CNC using the red button at the top of this page if you think we would be able to help with your machine. We cover the whole of the UK and Ireland.

We can help you book a service, get a quote for a repair, or help you purchase the best quality parts for your business.

Another day, another spindle! After more than a decade of solid service in an XYZ TC250, this spindle finally gave up.

As the photos show, coolant ingress over time washed the grease out of the bearings, causing them to heat up, dry out and eventually fail.

Coolant and oil mist inhalation from machine operations can put the operator’s health and anyone else in the vicinity at risk.

Metalworking fluids can be carcinogenic, so it is important to protect your workforce from these dangerous substances.
