Troubleshooting
If a nonredundant Coordinator Processor card is disabled on a running
process, all operator process changes, links between controllers in that
cage, and links to and from that ControlFile will freeze at the last value
received. The controller will continue to operate the process under these
conditions. As soon as the Coordinator Processor is restarted, all links will
be updated.
If a Controller Processor card is disabled on a running process, the analog
output Field interface card and the discrete output module will either hold
their last value or go to zero, depending on the position of the jumper on
the Field interface card. If it is necessary to close (go to zero) the output of
the field device that uses the ”HOLD” mode after the controller is disabled,
the Field Interface card must be removed.
If both PeerWay Buffer cards are removed from the ControlFile on a
running process, all operator changes and links to and from this ControlFile
will freeze at the last value received. The links within the C ontrolFile will
continue to update. The Controller Processors will continue to operate
under these conditions.
