Table 20: IEC 61850-8-1 MMS settings
Parameter Values (Range)
Unit mode
1) MMS client expects primary values from event reporting and data attribute reads
2) MMS client expects nominal values from event reporting and data attribute reads; this is the default for PCM600
3) For PCM600 use only, When Unit mode is set to "Primary", the PCM600 client can force its session to "Nominal" by selecting "Primary-
Nominal" and thus parameterizing in native form. The selection is not stored and is therefore effective only for one session. This value has
no effect if selected via the LHMI.

Description
IEC 61850-8-1 unit mode
Description
Enable or disable this protocol instance
Port selection for this protocol instance.
Select between serial and Ethernet based
communication.
Chooses which mapping scheme will be
used for this protocol instance.
Unit address
Selects between ASCII and RTU mode.
For TCP, this should always be RTU.
Defines the listening port for the Modbus
TCP server. Default = 502.
Parity for the serial connection.
