Hey guys!
I have come across an unique issue. Hoping that I can find some solution here.
I want to replace an existing S7-1214 DC/DC/DC plc with 4AI/2AO module with a newer version of same model PLC but with different programming as I cannot access old program due to V13 in the existing PLC. I am using V15.1.
The issue is that when I am downloading HW configuration into my PLC, the analog module lights up Flashing Red; when checked in Diagnostics, it said that "Missing supply voltage". But there was 24VDC supply when i physically checked the same.
Moreover, I was surprised when I connected the old PLC and found that the Analog module LED was OK.
Please help!!!
