Faceplate Expression not working for Control Operation
This question is related to the previos ques which I asked a couple of days ago regarding the faceplate expressions for controlling the breaker, Isolator & Earth Swtich.
Issue is I am able to control the CB,ISO & ES using control selection & control operation from CET. Its working fine when I do the write command from the CET. however its not working in 800xA.
for simplicity I used the same expressions given in IEC61850 manual for CB, ISO & ES Control. but those expressions are also not able to provide the healthy status of buttons as shown in screenshot.
I see no other options other than asking the experts here. I can send the pcmi file via mail if required.
Please suggest something so that control operation is possible from faceplate.
Thanks & regards
