2.6 Communications with a Mitsubishi PLC (A-compatible 1E Frame protocol)
Message Functions
2-112
Abort
Specify the bit to use to abort the message transmission.
When the Abort Bit turns ON, the message transmission will be stopped unconditionally. The Abort Bit
takes precedence over the Execute Bit.
Dev-Typ (Communications Device Type)
Specify the type code of the communications device.
Pro-Typ (Communications Protocol)
Specify the type code of the communications protocol.
Cir-No (Circuit Number)
Specify the circuit number for the communications device.
Specify the same circuit number as displayed in the MPE720 Module Configuration Definition Tab Page.
The following table gives the valid circuit numbers.
