Hi,

I have Faceplate (UDT) that could be edited from both HMI and PLC.

I encounter specific problem: I editing data on internal HMI tags i.e. Name, Destination etc. and after User pressed "Save" button, script is called that write data from internal tags to Faceplate (UDT) linked to PLC (symbolic access) and set bool "SaveDone" to 1 .

On PLC I have FC that check if button was pressed and only once write data from Faceplate (with new data from internal HMI tags) to appropriate DataBlock and continuously write data from that DataBlock to faceplate.

But problem is when i pressed "Save" button data is not write from Faceplate to DataBlock, it looks like first MOVE function dose not work or HMI not send whole Faceplate at once and i.e. PLC recived "SaveDone" before rest of data.

Program structure add on picture

I am grateful for any help.

Hello,

not really sure but something I see here - you have reset at same time this input signal with this MOVE procedure. Really, it isn't clear if all was sucessfully moved in this procedure, in my opinion. It says to me that you need do some changes with check that last data is changed/moved compared to previous state. It is up to you how to do that, only after that check you can reset input signal of MOVE procedure. I think, here is the problem you have.

Hello lysaw,

is it working if SaveDone is not reset automatically in PLC?
