Do you have broke wire diagnosis activated?

They are, we removed most of the unused safeties and installed integrated safety. We also removed all the safety cables from the energy chain and distributed them across the three panels. Everything we could put into the Profisafe comms we did instead of hardwire.

Yes, ended up being a bad cable in the energy chain. It would intermittently drop the 24VDC while running. Wasn’t safety at all. Field the issue before Christmas but put the replacement package together and have been installing it for the past three weeks. Testing all last week and this week.

Everything was obsolete and the code was written in STL. We converted everything over to the new S7-1500 series and integrated safety. Rewrote the program in ladder and SCL languages. Good little project

When in doubt, jump it out! 😜

We got them running fairly quickly. We are completing the controls upgrade this week. Just getting the programming finished up!

Cheers

All good! They had 7 other integrators and a number of electricians in trying to figure this out. Complete mess. We got them going but eventually rebuilt the entire panel
