Simulated connection Unified and PLC

Hello,

i have got simulate the PLC (plcsim) and RT (localhost), the problem is PLC doesn't react for RT command.
If you change something in PLC, the runtime show the variable has been changed, but if u want do something on RT, the PLC doesn't react.
I dont know where should i looking for the answer.
I have one project, where the simulate works well, but truly... i dont know how i did that. I had the same problem, but i solved it, somehow. Im trying compare both projects, but without any results.

In both cases i used CopyPLC and copy project from IPC to normal PLC.

Any advice?

Hi AttA2000,

What action are you exactly trying to trigger within the PLC from the RT?

AFAIK, there is a folder within the TIA Portal project that get corrupted often and therefore missbehaviour could happen when simulate or running.

I suggest to follow the steps from below FAQ:

Hope it helps

Thank you.
I mean any variable. No one react for push/active etc. But if u change something in PLC, the RT show the changed variable.
I will check it and give the response.

Check if the User you are logged in with have the "HMI Client Monitor Role" Active.
If this is active this will overrule the other access right and disable the option to edit tags in the PLC.

Try to disable this option, rebuild and download all inclouding the new user login settings.

 Thanks very much.

It works, but i don't so sure, what is reason, again.
But it very possible, the HMI Monitor Client should be off.

I will reopen this topic if i get more problems of that.
