Mistic PIDs Reconfigured when Communication to I/O Unit Re-enabled
- SNAP-PAC-S1, SNAP-PAC-S1-FM, SNAP-PAC-S1-W
- SNAP-PAC-S2, SNAP-PAC-S2-W
R10.0d through 10.3a (may affect earlier versions)
Resolved In Version:
If you have a Mistic I/O unit configured with PIDs, when you enable communication to the Mistic I/O unit, the current values in the PID are overwritten by initial values (as configured in the strategy). This occurs when you use PAC Control Debug mode to enable communication or the strategy uses one of the following commands:
- Enable Communications to I/O Unit (Mistic only)
- Enable Communications to all I/O Units (Mistic only)
- Enable I/O Unit Causing Current Error (Mistic only)
The PID values should not be overwritten.
Save any values you have changed, then restore those values after re-enabling communication.
