are included in the configuration with the Ethernet configuration
tool. In the SMT tool they can be mapped to the desired virtual
input (SMAI) of the IED and used internally in the configuration.

17.5.3.1 Output signals
SEMOD166622-1 v1
GUID-942C81AD-22D9-438F-95FA-1972BA2BE2E5 v1
The output signals are the same for all MUs so only the table for MU1_HW is
included in this manual.

MUDATA BOOLEAN Fatal error, data not received, transmission
errors, time-sync issues or inconsistent sample
rate
SYNCH
BOOLEAN High when IED clock is not within configured
accuracy or time domain
SMPLLOST BOOLEAN Fatal error or recovery state after fatal error. High
if any subscribed channel has bad quality or
TEST while IED not in test mode.
MUSYNCH
BOOLEAN MU not synced or MU clock not synced to same
clock as IED
TESTMODE BOOLEAN Quality of one or more subscribed analogue
channels is TEST
SIMMODE BOOLEAN MU delivers simulated data accepted by IED
