Siemens expansion modules

2 posts in this topic

Hy to all, I am working on my first project with Siemens S1200 so I have some beginners problems. I am using TIA portal V13 for programming. When I connect everything, and added new unknown device, TIA recognize my CPU and my SM module. So everything should be connected good. But when I go in monitoring mode, only inputs and outputs on CPU are working, changing inputs and outputs on SM doesn't do anything in the program. I have ? on SM module (see attachment). What I need to do in order to fix this? Thanks in advance for answers.

Hi kijo Have you connect power supply to this module? Did you made hardware compilation? Is the module the same on project as on reality? Did you look for corect adress ? some time we forgot that the CPU end at input I1.5 and output at Q 1.1..... Let us know dekor.
