4.25 Power Line Carrier (PLC) Data (PC)
The Power Line Carrier (PLC) data includes X-10 and other PLC interfaces.
H = House Code, ASCII “A” to “P”
UU = Unit Code, ASCII decimal 01 to 16
FF = Function Code as follows:
01 = X10_ALL_UNITS_OFF in a House code
02 = X10_ALL_LIGHTS_ON in a House code
03 = X10_UNIT_ON
04 = X10_UNIT_OFF
05 = X10_DIM, EE extended value holds number of dims
06 = X10_BRIGHT, EE extended value holds number of brights
07 = X10_ALL_LIGHTS_OFF in a House code
08 = X10_EXTENDED_CODE
09 = X10_PRESET_DIM, EE extended value hold level 0 to 99%
10 = X10_EXTENDED_DATA
11 = X10_STATUS_REQ
12 = X10_HAIL_REQUEST
13 = X10_HAIL_ACK, not used
14 = X10_STATUS_ON, not used
15 = X10_STATUS_OFF, not used
TTTT = ON Time in seconds, range - 0 to 9999 decimal
4.25.1 Control Any PLC Device (pc)
11pcHUUFFEETTTT00CC
11 – Length as ASCII hex
pc – PLC Control Command
H - House Code ‘A’ to ‘P’
UU – Unit Code ‘01’ to ‘16’
FF – Function Code ‘01’ to ‘16’
EE – Extended Code ‘00’ to ‘99’
Brightness percentage level for preset dim function (9) or
the number of dims for dim function (5), number of brights
for bright function (6).
TTTT – ON Time in seconds, range - 0 to 9999 decimal
00 – future use
CC – Checksum
Example: 11pcA01010000050043 House Code A, Unit 1, All Lights Off for
5 seconds, then turn back On.
