Reset Smart Module for ECM850
Service Request 24, Reset Smart Module can be used to reset an ECM850 in the RX3i CPU
rack. The result is the same as extracting the ECM850 from the rack then re-inserting it.
When the RX3i CPU encounters the Reset Smart Module service request in the application
logic, it issues a reset command to the specified module (in this case, a ECM850). The
ECM850 terminates all connections to IEC 61850 devices. When the ECM850 powers up and
re-establishes communications with the CPU, the CPU sends the ECM850 its configuration,
and the ECM850 re-establishes connections with all its configured IEC 61850 devices.
The Reset Smart Module request cannot be used to reset modules located in remote nodes.

Configuring SNTP for ECM850
In Machine Edition’s Hardware Configuration for the ECM850 on the Settings tab, configure
the items as described in the following sections.
Network Time Sync:
The location that the time stamp value for a ECM850 Local Log and IEC 61850 outputs is
obtained from.
•
None: The time stamp value for an ECM850 Local Log and IEC 61850 outputs is
obtained from the ECM850 local time (which is synchronized at power-up/restart
with controller's local clock). Time stamps of IEC 61850 outputs obtained by an
ECM850 with this setting (None) will not be in synchronization with the time stamps
of IED.
•
SNTP (Simple Network Timing Protocol): The time stamp value for a Local Log and
IEC 61850 outputs is obtained from the ECM850 which is synchronized to a central
clock, located on a user-supplied SNTP time server on the network. All ECM850s
configured with this setting (SNTP) have synchronized time stamps. Synchronized
time stamps enable you to compare groups of data to determine the order in which
they were written or to determine when outputs written to IED.
