G.1 Message Transmit Function (MSG-SND)
This section explains the message transmit function (MSG-SND) used in a ladder program when transmitting mes-
sages.
G.1.1 Specification Overview of the Message Transmit Function
* 1. The meanings of I/O options are as follows:
 B-VAL: Specify I/O by bit type data.
 I-REG: Specify I/O by integer type data. When specifying, set an integer type register number.
As for the input only, it can be a constant (literal).
 Address input: The address of the specified register (any integer register) is passed to the function.
* 2. When transmitting in MEMOBUS, Extended MEMOBUS, MELSEC, OMRON, or MODBUS/TCP protocol, set the
communication protocol (Pro-Typ) to MEMOBUS(=1). The communication device automatically converts the proto-
col.
* 3. Non-procedure 1: In non-procedural communication, data is transmitted on a per-word basis.
Non-procedure 2: In non-procedural communication, data is transmitted on a per-byte basis.
Function Name MSG-SND
Function
Transmits messages to a remote station on the circuit specified by the communication device type.
