ITMx Binary I/O M0 Control Test Coil Enable for State 2 issue

All other Test Masses are in State Request 2.0, but Jenne noticed ITMx has a RED bar for the TEST/COIL ENABLE (upper right on the main medm screen).
One can switch to State 0 & 1 and it is green and functioning, but seems to be an issue with State 2. Richard said it looks like a software (vs hardware) issue. So waiting on Rolf & Dave to take a look at this.
