G.1.4 Function Setting and Parameter Details for MEMOBUS and Extended MEMO-

BUS Protocols

This section explains the MSG-SND function setting and its parameter list details when MEMOBUS or Extended
MEMOBUS is used as a protocol type.

( 1 ) Message Transmit Function Setting

( a ) 218IFA Setting Example

An example of a function setting when 218IFA is used as a communication device follows:
Set the protocol type to MEMOBUS even when used in Extended MEMOBUS protocol.
Set the circuit number in accordance with the line number allocated to the target 218IFA.
Set a unique communication buffer channel for the same circuit.
For information on the register number, refer to G.1.2 ( 1 ) Input Item and G.1.2 ( 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 even when used in Extended MEMOBUS protocol.
Set the circuit number in accordance with the line number allocated to the target 218IF.
Set a unique communication buffer channel for the same circuit.
For information on the register number, refer to G.1.2 ( 1 ) Input Item and G.1.2 ( 2 ) Output Item.
