Station communication
20.3.4 Setting guidelines
Merging Units (MUs) have several settings on local HMI under:
• Main menu/Configuration/Analog modules/MUx:92xx. The corresponding settings are also
available in PST (PCM600).
• Main menu/Configuration/Communication/Merging units configuration/MUx:92xx. The
corresponding settings are also available in ECT (PCM600).
XX can take value 01–12.
20.3.4.1 Specific settings related to the IEC/UCA 61850-9-2LE communication
The process bus communication IEC/UCA 61850-9-2LE has specific settings, similar to the analog
inputs modules.
If there are more than one sample group involved, time synch is mandatory. If there is no time
synchronization, the protection functions will be blocked due to condition blocking.
CTStarPointx : These parameters specify the direction to or from object. See also section

SyncLostMode : If this parameter is set to Block and the IED hardware time synchronization is lost
or the synchronization to the MU time is lost, the protection functions in the list

Binary signals over LDCM are transmitted as valid and processed normally even
when analog signals are transmitted as invalid due to loss of communication or
loss of time synchronization.
