I deal with a strange problem.
A Customer his machine did nothing all of a sudden.
So, after searching a while, we found that no outputs are high, not a single one. PLC in Run, when I check with monitor in de HWConfig on the output cards, I can see a lot of outputs high, especially when we push on the button lamptest. All 24V on every output group is okay. We placed another output card, made the outputs high, this card works. We did not have spares for the cards used in that machine. We will buy the right spares...
Is it possible that all outputs are blew up ? In the HWConfig, the outputs that are high are not high electrical...
The power supply's of the cards are all connected together and some cables have 230V and 24V together... I'm thinking in the direction of 230V that came on the power supply of the outputcards... The CPU is in Run and says that all cards are in good condition...
In my 10 years carreer I've never seen this.
All input cards are okay...
Suggestions ?
Thanks,
Regards,
Gerry
