SNAP-PAC-S1-FM
SNAP-PAC-S2
SNAP-PAC-S2-W

Versions Affected:

Version affected: R9.4a
Problem is fixed in version: R9.4b

Resolved In Version:

Problem is fixed in version: R9.4b


Symptoms:

Attempting to change any value of a PID on a serial or Ethernet brain via the PAC Control debugger causes the controller's host port to become unresponsive. Once this has occurred, charts attempting to communicate with any I/O unit on that same serial port as the I/O unit with the PID loop also become unresponsive. The controller must be rebooted.
