Dear Members, I'm facing a strange problem with a micro-automation project done in Siemens S7-1200 PLC. The small program I wrote compiles perfectly, and downloads successfully. But the CPU does not go into RUN mode. Diagnostics buffer shows "New startup inhibit information - Current CPU operating state: STOP". Also reports, "Pending startup inhibit(s): - HW configuration inconsistent (TIA portal activity) - Manual warm start required." Even Some Times : "Power Supply Missing" & "Module Exists and has Fault" I did the HW configuration alright, I know. Diagnostics status shows "The loaded configuration and the offline project are not identical. The online and offline module configuration data are different. Order number: 6ES7 214-1AE30-0XB0 Configured order number: 6ES7 214-1AE30-0XB0" The reported numbers are exactly same, I can't see why it's saying that the configurations are different. I tried to press the "RUN" button in online panel, I saw network activity in the CPU (Rx/Tx LEDs), RUN/STOP, Error, Maint LEDs blink. But the CPU does not start and repeats the above messages in diagnostics. I tried memory reset (MRES in online panel) also. Same result. I also tried to download a new project. That also behaved in this way. Most importantly, I changed the CPU, and the new CPU also did this same thing, which surprised me very, very much. FYI: I Have used CPU 1214C, TIA Portal V10.5 SP2 & Firmware V1.0 Anyone experienced similar behavior? All helps are appreciated. Thanks & Regards Prem Kumar.P, Chennai, India.
