The network addressing of the DSLC-2 / MSLC-2 allows up to 32 DSLC-2s and 16 MSLC-2s in an ap

plication. A DSLC-2 and MSLC-2 application can handle 8 segments. Discrete inputs inform the DSLC

2s and MSLC-2s which segments each generator and utilities are operating on. If a MSLC-2 receives a

discrete input to activate segment 1 and 2. it will share this information with all controls over the Ether

net bus. It is not necessary to provide a segment activation discrete input to all controls. Segmenting

allows the DSLC-2s and MSLC-2s to remain connected thru the Ethernet bus, but be operating on sep

arate load buses.

The DSLC-2 / MSLC-2 system can be applied according to following rules:

• The maximum number of DSLC-2s (Gen-CB) is 32.

• The maximum number of MSLC-2s (Utility- or Tie-CB) is 16.

• The maximum number of segments is 8.

• The segment numbers have to follow a line, which can finally be closed to a ring.

• For DSLC-2 it can be selected between two segmenting modes:

o Bus segmenting determining generators running together via an algorithm.

o Device segmenting determining generators running together from outside.

• Only one MSLC-2 can be used as master control, when multiple MSLC-2 is resided in one segment.

o The MSLC-2 with the lower device number will control if multiple Utility MSLC-2s are

active on the same segment

• The generator is not counted as a segment.

• The utility is not counted as a segment.
