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.
18.3.2.1
Specific settings related to the IEC 61850-9-2LE communication
The process bus communication IEC 61850-9-2LE have specific settings, similar to the analog
inputs modules.
Besides the names of the merging unit channels (that can be edited only from PCM600, not from
the local HMI) there are important settings related to the merging units and time synchronization
of the signals:
If there are more than one sample group involved, then time synch is mandatory and the
protection functions will be blocked if there is no time synchronization.
SmpGrp – this setting parameter is not used
CTStarPointx : This parameter specifies the direction to or from object. See also section
current
channels".
AppSynch : If this parameter is set to Synch and the IED HW-time synchronization is lost or the
synchronization to the MU time is lost, the protection functions in the list
the output SYNCH will be set.
SynchMode : marks how the IED will receive the data coming from a merging unit:
•
if it is set to
"SmpSynch" flag
•
If it is set to
•
setting
For more information on the settings, see "MU1_4I_4U Non group settings (basic)" table.
18.3.2.2
Loss of communication
If IEC 61850-9-2LE communication is lost, see examples in figures 215,
functions in table 45are blocked.
Case 1:
Application manual
When changing the sending (MU unit) MAC address, a reboot of the IED is required.
NoSynch , then when the sampled values arrive, there will be no check on the
Operation , the "SmpSynch" flag will be checked all time.
Init , should not be used
