Hi there.

I found a problem using faceplates in Tia portal versions 14 and 15. Panels Tp1200 comfort, TP 1900 comfort and plc's 1512 or 1511.

I have created a faceplate of the page with mixing parameters as an interface I use user defined data type containing 16 tags  time with linear scaling so the user sets the values directly in seconds or minutes . For all the values I have set the minimum limit, so the operator can't put les than 3 seconds for the pause of the mixing. The interface tag is linked to structure inside the plc.

And the problem : when operator sets the new value of one of the tags, the new value is displayed in the panel for about 0,5 - 1 second  after that the old value is restored.

Usually the operator must put the new value at least 2-4 times until it is written properly to the plc. 

I tried changing the time for tags synchronization plc - hmi  I have checked the communication settings.

Maybe someone had same problem, or any ideas where to start checking to fix the problem?

Hello Sliwka,

where in the PLC do you write your data to?

You should use an own DB in your PLC which is connected to your faceplate interface.
