I have been trying to generrate module LED status information using SFC 51 to send to SCADA. Have a good idea of what i'm doing, just want the benifit of someone elses experience. How to recieve and interpret information.
Thanks...

 

Use SFC51 with SSL_ID W#16#0119 for S7-300/400
SSL_ID=W#16#0174 for H-Redundant CPUs.

All the best.
