SNAP-PAC-R unit watchdog timers sometimes time out unexpectedly


Applies To:

SNAP-PAC-R1
SNAP-PAC-R2

Versions Affected:

Problem was discovered in version: R8.0a
Problem is fixed in version: R8.1a

Resolved In Version:

Problem is fixed in version: R8.1a


Symptoms:

Watchdog timers configured on points local to the controller, may time out even though the controller is accessing its own I/O points. Controller communication transactions to its own I/O unit, do not reset the watchdog timer with each transaction. As a result, if nothing else is communicating with the OptoMMP port (default 2001), the watchdog timer times out, and output points related to the watchdog will go to their pre-defined states.


Resolution:

Opto 22 has resolved this issue.
