Hello to everybody. I have this question:

I made a ladder program in Step7 and i have connexion with Wincc 2008.

The problem is that when i am changing the inputs from the Step7 Simulator, the program runs corectly!!!
but when i want to use buttons from Wincc to change the inputs of simulator, it doesnt work and the input it doesnt change.

Does anybody have any idea how I can fix it.

Thank you

you can`t change inputs from HMI!!

On PLCsim you should be able to chane inputs from HMI, as long as your CPU is not configured as a 315-2DP cpu or equivalent. PLCsim handles I/O differently depending on the CPU type. Try changing the CPU to something like a CPU314 and it should work (easiest is to create a new project with just new hardware config and download only hardware config, then use existing project for downloading PLC program blocks)
