3.1.4 Specifying Broadcast
This function allows multiple instruments specified by respective addresses to receive
commands.
(1) Broadcast specification is executed with the following addresses specified to the
address No. in the command:
“00”: All controllers supporting Modbus on network
“F9”: All UTAdvanced controllers on network
(2) This command functions regardless of communication address.
(3) This address can be used only for writing.
(4) When communication is performed with this address specified, the UTAdvanced that
receives the command does not return a response.
Note
If existing communication programs created in GREEN Series controllers are used in the
UTAdvanced, a UTAdvanced controller behaves as a GREEN Series controller in terms of
device information response via communication and broadcasting by setting the GREEN Series
device response (C.GRN) register to 1: ON.
However, in this case, the command "F9" is disregarded.
