G.2.6 Function Setting and Parameter Details for MODBUS/TCP Protocol
This section explains the MSG-RCV function setting and its parameter list details when MODBUS/TCP is used as a
protocol.
( 1 ) Message Receive Function Setting
[ a ] 218IFA Setting Example
An example of a function setting when 218IFA is used as a transmission device follows:
Set the protocol type to MEMOBUS when used in MODBUS/TCP protocol.
Set the circuit number in accordance with the circuit number allocated to the target 218IFA.
Set a unique communication buffer channel number for the same circuit.
For information on the register number, refer to in
G.2.2 ( 1 ) Input Item
and
G.2.2 ( 2 ) Output Item
.
[ b ] 218IF Setting Example
An example of a function setting when 218IF is used as a communication device follows:
Set the protocol type to MEMOBUS when used in MODBUS/TCP protocol.
Set the circuit number in accordance with the circuit number allocated to the target 218IF.
Set a unique communication buffer channel number for the same circuit.
For information on the register number, refer to
G.2.2 ( 1 ) Input Item
and
G.2.2 ( 2 ) Output Item
.
( 2 ) Process Result (PARAM00)
Refer to G.2.4 Function Setting and Parameter Details for MEMOBUS and Extended MEMOBUS Protocols.
