Lighting Group Objects
Individual binary outputs can be grouped together to
represent the logical layout of a building installation.
Sixteen lighting groups (LG) are available and each one
can contain a group of 33 outputs.
Lighting Group Output Registers (Coils)
Actual value registers start at 301. The Lighting Group
and OutOfService property can be commanded by
Function Code 05 and 15 and read by Function Code 1
and are mapped to Lighting Group Instances 1–16. The
value in the register represents the Lighting Group’s
PresentValue.The Lighting Group output registers are
listed inTable 43.

Sample Packets
Table44 is an example of a request for LG Value Reg302
to Reg305 (Function Code 1, LG2 – LG5 in map).
Note that the status of outputs 5–2 is hex 0B or binary
0000 1011, where LG302 is the LSB and LG305 is the
fourth bit from the left. Unused bits are padded as zero.

Lighting Group Setup Registers
The Lighting Group setup parameters are assigned a
block of holding registers starting at 4001 as indicated in
table 47. Lighting Group properties can be commanded
