Hicheichaa, I want to know what type of plc ur using & u told the "power on" green led is oscillating ,,checkit s blinking in green or red. What is the status of cpu run, stop or error ???? Are ur able to force a output of the cpu ??? Is every other modules like DI or DO power led is blinking???? Check the wiring whether u missed any -ve's!!! According to my knowledge i think that ur module havent established communication with PLC so check whether all the modules are interlocked physically.Still not achieved then reset the cpu by using "reset to factory settings" in the online & Diagnostics & download a fresh prog with new HW cofiguration. Hope it helps. Regards, Nelliyan.G
