A.1 Message Receive Function (MSG-RCV)
If the controller automatic receive function is not used, a MSG-RSV command must be included
in the controller’s ladder program.
A.1.1 Outline of Message Receive Function Specifications
* To communicate with MELSEC, OMRON, or MODBUS protocols, set the communications
protocol (PRO-TYP) to MEMOBUS ( = 1). The protocol is converted by the Communications
Device (217IF, 218IF).
Function
