2.3.4.2 Watchdog Timer
A hardware timer which is cleared periodically by software is provided and it is checked that the
software is running normally.
2.3.4.3 DC Supply monitoring
The secondary voltage level of the built-in DC/DC converter is monitored and checked that the
DC voltage is within a prescribed range.
2.3.4.4 PLC Data and IEC61850 Mapping Data Monitoring
Errors in PLC data or IEC61850 mapping data can prevent correct operation. Therefore, the
PLC data and IEC61850 mapping data are monitored and an alarm is issued if errors are
detected.
2.3.4.5 IEC61850 Communication Monitoring
The sending and receiving functions in the Ethernet LAN communication are monitored. The
receiving function is monitored by checking GOOSE message receiving status, and the sending
function is monitored by checking the Ping response to the other party. If a failure is detected, an
alarm is issued.
2.3.4.6 Failure Alarms
When a failure is detected by the automatic supervision, it is followed with LED indication,
external alarms and event recording.

(1) The binary output relay “FAIL” operates.
(2) It depends on the degree of voltage drop.
2.3.5 Event Recording
The events shown are recorded with a 1 ms resolution time-tag when the status changes. The
user can set a maximum of 128 recording items, and their status change mode. The event items
can be assigned to a signal number in the signal list. The status change mode is set to “On” (only
recording On transitions) or “On/Off”(recording both On and Off transitions) mode by setting.
The “On/Off” mode events are specified by “Bi-trigger events” setting. If the “Bi-trigger events”
is set to “100”, No.1 to 100 events are “On/Off” mode and No.101 to 128 events are “On” mode.
The name of an event can only be set by RSM100. Maximum 22 characters can be set and can
be viewed on the RSM Setting screen.
The elements necessary for event recording and their setting ranges are shown in the table
below. The default setting of event record is shown in Appendix D.
