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.
