Hi everybody,I have sent a post yesterday concerning no output on my plc, I need to rectify something. The problem is that I don’t get any outputs on my plc.
Firstly, the machine was in good running condition till some days back .
It is equiped with a siemen plc Step 7 and it is on the run mode.
Power supply L+ and common to the card is good 24vdc and I have all the necessary inputs.
I don’t have access to the program via software.
No led lit and no voltage on any outputs(None of the outputs are functionning).
Any suggestion is the most welcome.Thank you.
Thanks to Glaverty, Mike willams, Platootod and Tom jerkins for their previous replies.
