Variables are not shown on the screen. Operator terminal expert and HVAC Machine Expert

[Luca22]

I'm using an HMIST6400 screen that communicates with an M171P PLC (with an extension).
I inserted all the registers of the PLC variables into the Operator terminal expert software.
I have created some graphic pages in which there are objects connected to my variables, but for some of these I am having problems, in fact some objects are seen with a white box and a red border.
These objects are connected to registers found in the PLC expansion (but be careful not all the expansion objects give me these problems, some are visible correctly).
The strange thing is that if, for example, I isolate one of these elements and then put it on a different page, alone, then the object appears correctly.
Could anyone tell me why?

Hi,

Nice visualisation.

Your problem is that you need continous adresses in ESME HVAC. If you have one address open and not assigned EOTE will generate a communiction fault. Becaus EOTE will always optimize the communication and will read so much values in one telegram as possible. If you recalc the values in ESME HVAC and reimport them in EOTE the problem should be fixed. You know the Process how you could export values from ESME HVAC and import them in EOTE?
