4-16
pmp-0049 (September 2012)
A reboot causes the preset time to pause or, in some cases, to run in reverse. Additionally, a power
cycle resets the running time and date to the default 00:00:00 UT : 01/01/00. Thus, whenever either a
reboot or a power cycle has occurred, you should reset the time and date in the Time & Date web page
of any module that is not set to receive sync.
Event Log Data Collection
The collection of event data continues through reboots and power cycles. When the buffer allowance
for event log data is reached, the system adds new data into the log and discards an identical amount of
the oldest data.
Each line that contains the expression WatchDog flags an event that was both
considered by the system software to have been an exception
recorded in the preceding line.
Conversely, a Fatal Error() message flags an event that is recorded in the next line. Some exceptions and
fatal errors may be significant and require either operator action or technical support.

Messages that Flag Abnormal Events
The messages listed below flag abnormal events and, case by case, may signal the need for corrective
action or technical support.

Something is interfering with the control messaging of the module. Also
ensure that you are using shielded cables to minimize interference.
Consider trying different frequency options to eliminate or reduce
interference.
