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.

Input Item
1 Execute DB000200
Executes a transmission
When Execute turns ON, the message transmission is carried out.
2 Abort DB000201
Aborts a transmission
When the Abort bit turns ON, message transmission is forcibly
stopped.
3 Dev-Typ 00016
Communication device type
Specify the type of the communication device used in transmission.
When Ethernet (218IF) is used, specify “16.”
4 Pro-Typ 00001
Communication protocol
Specify the type of the communication protocol.
MEMOBUS(*1) = 1, non-procedure 1(*2) = 2, non-procedure 2(*2)
= 3
5 Cir-No 00001
Circuit number
Specify a circuit number of the communication device.
Specify it in accordance with the circuit number displayed in the
MPE720 module configuration definition screen.
6 Ch-No 00003
Communication buffer channel number
Specify the channel number of a communication buffer.
When Ethernet (218IF) is used, specify it in the range between “1”
and “4.”
Note: Set up a unique channel number in the line.
7 Param DA00000
Parameter list start address
Specify the start address of the parameter list. For the Parameter List,
17 words are automatically assigned from the configured address.
Output Item
1 Busy DB000210
In process
