Hey all...have a good one for you this morning.
I'm using a CompactLogix to talk through ethernet I/P to a Panelview +600. I have a screen setup with a single line information message display. That display looks at the value of a DINT tag in the PLC to determine which message to display.
Everything works well; when I turn on a bit in the DINT on the PLC side, the appropriate message is displayed. However, when I turn off the bit, so that no message should be displayed (DINT value of 0), the entire screen disappears! All I see is a grey background and a mouse pointer.
The odd (er) thing is that the current display value tag in the PLC shows the correct screen number - but nothing is shown. If I switch (from the PLC, because I have no buttons) to another screen and then back again, everything is fine except the information message display, which shows a line of "????????"
Any thoughts on this?
