Input/output definitions for message transmit functions
The input/output definitions for the message transmit function are explained 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 communications, data is transmitted on a per-word basis.
Non-procedure 2: In non-procedural communications, data is transmitted on a per-byte basis.

Explanation
Input Item
1 Execute DB000200
Executes a transmission
When the Execute bit is ON, the message is transmitted.
2 Abort DB000201
Aborts a transmission
When the Abort bit is ON, the message transmission is forcibly
stopped.
3 Dev-Typ 00006
Communication device type
Specify the type of the communication device used in transmission.
When Ethernet (218IF) is used, specify “6”.
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 the 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 00001
Communication buffer channel number
Specify the channel number of the communication buffer.
When Ethernet (218IF) is used, specify it in the range between “1”
and “10”.
Note: Set up a unique channel number in the circuit.
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
Busy is turned ON while executing a message transmission or forced
abort process.
2 Complete DB000211
Process completed
When a message transmission or abort process is properly completed
properly, Complete will turn ON only for one scan.
3 Error DB000212
Error occurred
When an error occurs, the Error bit will turn ON only for one scan.
