Hello muratb, my first thought was: Load a newer Firmware Version. But, ... think you allready got the newest available one Operating System Update for SIMATIC S7-1200 CPU Firmware V3 So I would suggest to contact the Technical Support via Support Request. Maybe they got a newer one? Please keep us up to date. Thank you Sabine |

If you use relay outputs, the inductive problem still exists but is less likely to affect the output module. Rather it will simply reduce the life of the output contacts. If you have a 24vdc coil on a plc output, you should add appropriate diode, and/or snubber. Maybe this link will help: http://electronics.stackexchange.com/questions/26140/inductive-kick-back-voltage-calculation |
