Sending a Command from Siemens Step7 to WINCC


Thread Starter


I know it is possible to use step 7 logic to command the wincc HMI to change to a specific screen. I just cant remember how it is done. I tried manipulating the screen number in DB67, but that does not work.

It's possible by means area pointer in WinCC Flex in "Connections".
In PLC side you have to set a job function.
Search in WinCC communications manual.
