Hello, we've got a client with multiple IO drops connected to Quantum PLCs. I noticed that some Digital output modules have the F (fault led) on. No error in PLC diag buffer and everything works fine. Schneider documentation says that "An error (external to the module) has been detected... The only thing that comes to mind is that some cards have missing group 24vdc supplies (because the outputs are not used).
Anybody got any more information?
Thanks!
