Siemens S5-95U Onboard Analog

bluenoser337 · Mar 15, 2011

I have a system with this PLC and there are 8 analog input devices connected to the onboard A/I terminals. In the program, I can only find PW40 and PW48. I should be able to find them all from 40 to 54. What could I be missing? Thanks!

The Inputs may be indirectly addressed. Try searching for PW0.

The code may look like:

Code:

L KF +40
T FW 200         FW200 Contains 40
DO FW 200
L PW0            Will Load PW 40

Thanks Mangle...No luck with that search. I can find all the analog input code (I think). Some appear to be for cards that don't exist? Example: BG KF8, KNKT 1,4. If some analog were only there for HMI display, is it possible that they wouldn't have code and the HMI may address them directly with PW42, etc?
