Hi all,

Pretty much stated my problem in the title.

When I simulate my HMI screen in TIA, when connected to an actual 1200 PLC, no values are shown. This seems to work with 300 or 1500 PLC's.

Am I doing something wrong?

Thanks!

Hi Ton - how are you these days?

Set the PG/PC Interface in Windows Control Panel
(S7ONLINE must set to the Interface to which the PLC is connected to the PC)

Then click the simulate button of the HMI in TIA Portal and it should work.

Strange that you would not have an issue
with the S7-1500 but the S7-1200 (?).
See if that helps you.

I will give that a shot, thank you!

(Other than that, I am good as always! :) , hope you are too! )
