nviClearStat
(Clear
Statistics) SNVT_switch When diagnosing a network problem,
it may be useful to use this network
variable to clear all of the router
statistics and error log after corrective
actions have been taken, so that one
can verify whether or not the actions
were effective. The Status LEDs on
the front panel, if they indicated error
conditions, will also revert to their
normal status indications, until
another error occurs.
It is not necessary to set the network
variable to OFF. It automatically sets
itself to OFF once the ON state is
detected. The value field of this
network variable is ignored by the
Node Object; however, the network
tool should send valid values.
The default state is OFF.
The Status LED behavior is described
in Chapter 2, MPR-50 Multi-Port
Router Hardware and Software. The
error log is described in the Error Log
section, later in this chapter.
nvoElapsedTime
(Elapsed Time) SNVT_elapsed_time Elapsed time since power-up or last
reset. Normally used to compute at
what time in the past events logged in
the error log occurred. The MPR-50
does not have a real-time clock, which
means this variable is subject to
accuracy errors particularly over long
periods of time.
nvoAlarm2
(Alarm) SNVT_alarm_2 Used to transmit alarm data for each
functional block on the device
whenever an alarm occurs or is
cleared, and upon request. For more
information, see the Alarms section,
later in this chapter.
