Versions Affected:

For groov EPICs: All versions prior to 4.1.0
For SNAP PACs: R10.4e to R10.6a

Resolved In Version:

For groov EPICs: 4.1.0
For SNAP PACs: R10.6b

Symptoms:

If your PAC Control strategy periodically turns on a digital output channel on a groov I/O module, and you have redundant Ethernet links (only available with PAC Control Professional) between an affected processor/controller and the EPIC with the groov I/O module, switching from the active network to the alternate network may cause all digital channels of the module to turn on.
