It was all working great .. for a while. Every time I turned on the system (PLC, HMI, ethernet switch) .. everything would go "green" and it all worked fine. Then, just for training, I added good stuff like delays, and a math function, and a few more goodies on the HMI.
When connected to the PC (TIA) during programming … everything loaded.."green board" all around .. (always checked the little box for auto run at startup).
HMI worked great, PLC worked great.. everything functioned as expected. The PLC responded to the HMI buttons. Then I added a nice new I/O Module. Didn't use it in any program yet… Just connected it to the PLC. On power-up .. the module indicated a flashing green LED. Focused on the module, hit "download" .. and after TIA loaded some spurious stuff, which didn't make much sense, the modules LED went green … Great!
Everything working (green) so, I tested all equipment.. and everything worked great. then shut it all off (Master Power) .. and .. turned it back on, expecting all to initialize back to green, PLC to "auto-run". But, Nooooo Not the PLC. (everything else was up and working fine).
I had to go back on line, and initiate PLC "Run" mode the hard way .. along the way.. the TIA tells me my PLC is "Not the PLC I'm looking for" .. (the one I'm trying to "run" is not the one in the program) DUH …
I don't care…I say, go online, launch it anyway. TIA does, and all is well ..green lights everywhere…working fine. It's apparent, I can never turn the system off… sigh!
TIA Portal is V11 SP2 #5 Upgrade
PLC is S7 1200 ...1212C (6ES7-212-1BD30-0XB0) Firmware 2.02 (can't go any higher than 2.2 ..without exploding)
HMI is KTP 600 Basic PN (6AV6647-0AD11-3AX0)
I/O Module SM 1223 (8)24DC in/(8)24DC out (6ES7223-1BH32-0XB0) .. yes … it's 2 years newer than the PLC.. but Siemens says it's compatible with this TIA & PLC … but, nothing is connected to it yet.. nor is anything in the program.. yet.
Any Idea what's preventing the PLC from "Auto Run at Startup" … ? (remember, I always check that little box during downloads)
Thanks… Regards, Michael
