Hi bro, my case is actually similar with yours which is I cant communicate between my PLC and panelview800, I am not sure for this step that you mention here, I have configured the tags in studio 5000 by moving those tags into controller tag and others is same , but I still get the error in HMI which shows "10:write error for alias WTAG0001, Controller PLC-1, address is WTAG0001, Communication Flag is 0". Is it anything I could miss it ?
WTAG0001 is a tag name for the momentary push button in CCW
