EXAMPLE 3:
Hexadecimal notation for a TCP frame that triggers scene No 1:
00 00 00 00 00 0B 00 45 01 00 00 00 01 00 00 00 00
lub
00 00 00 00 00 07 00 45 01 00 00 00 01
PDU explained:
45
– Modbus function code: 0x45 = 69, triggering an action
01
– “ s cene start” action
00 00 00 01
– f irst argument - scene number
00 00 00 00
– s econd argument – not used in this case
It can be omitted in respect of actions that do not require a second argument (but remember to
change the value of “Length” field from 0x0B to 0x07).
Scene and program numbers are assigned when the configuration is uploaded into the controller.
In order to identify the index of a scene or a program uploaded into the controller, start the
relevant element and read the number as shown in the controller preview.
When sending or receiving multiple parameters using a single command (e.g. “Write Multiple
Registers” - function code 0x10) you can transmit up 125 values in one message.
