 Input/output definition contents for message transmit functions
The input/output definition content for the message transmit function is as follows:
* 1. When transmitting in MEMOBUS, Extended MEMOBUS, MELSEC, or MODBUS/TCP protocol, set
the communication protocol (Pro-Typ) to MEMOBUS(=1). The communication device automatically
converts the protocol.
* 2. 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.
