G.1 Message Transmit Function (MSG-SND)
A-52
G.1.2 I/O Item Details of the Message Transmit Function
( 1 ) Input Item
The following table shows registers available for each input item.
1.
Execute (executes a transmission)
Specifies a bit to command execution of a message transmission.
When the Execute bit turns ON, message transmission is implemented. To execute the process, a ladder program
or the like needs to be used to switch it ON/OFF.
Note: Keep Execute (executes a transmission) ON until Complete (process completed) or Error (error
occurred) is turned ON. When the command turns ON, the message transmission is implemented.
To continuously command the transmit execution, make sure to turn Execute (executes a trans-
mission) OFF for one scan or more.
2. Abort (forcibly ends a transmission)
Specify a bit to command a forced terminated of a message transmission.
When the Abort bit turns ON, the message transmission is forcibly terminated. Abort takes precedence over Exe-
cute.
In order to execute the forced abort, a ladder program or the like needs to be used to switch it ON/OFF.
3.
Dev-Typ (communication device type)
Specify the type code of the communication device (refer to the table below).
4. Pro-Typ (communication protocol)
Specify the type code of the communication device (refer to the table below).

Type Code Communication Protocol Remarks
1 MEMOBUS
Set the type code to “1” when also transmitting using Extended MEMO-
BUS, MELSEC, or MODBUS/TCP protocol.
The communication device automatically converts the protocol.
2
Non-procedure 1
(per word) Data is transmitted on a per-word basis in non-procedural communica-
tion. No response is received from the remote.
3
Non-procedure 2
(per byte) Data is transmitted on a per-byte basis in the non-procedural communi-
cation. No response is received from the remote.
