I expect screen 2 displaying when the program running. Did I miss something? Because it does not work. Here is what I use: Software: SIMATIC STEP 7 BASIC V11 SP2 SE PLC: CPU1211C DC/DC/DC HMI: KTP400 BASIC COLOR PN

Here is what I use: Software: SIMATIC STEP 7 BASIC V11 SP2 SE PLC: CPU1211C DC/DC/DC HMI: KTP400 BASIC COLOR PN Not 100% sure, but I think it is more difficult to get the 400 to change screens than say the 600 and up. The 400's are very limited in what they can do. As a result, we upgraded our 400's to 600's and it was so much easier to do the things we wanted. TIA Portal sets up both the area coordination, where you can send a job to the hmi to change screens and compare to the current on display screen, and an hmi tag that can trigger a screen change based on another tag. I had a more difficult time getting the 400 screen to change but using the job and area coordination was able to do it. With the trigger (the obvious preferred method) did not work for me.
