6.2 Communication with Other MP Series
6.2.4 When the CPU-03/CPU-04 Acts as Master (ladder program which uses MSG-SND function)
4.
Create a ladder program with a message receive function (MSG-RCV) in it.
An example of a ladder program for receiving messages in the remote device (MP2300) side follows:

Message receive function (MSG-RCV)
This system function is required for receiving messages. Message reception is carried out by describing and exe-
cuting this message receive function in a ladder program.
In addition, in order to support Read and Write by CPU-03/CPU-04, two message receive functions should be
provided. Here, the input item and parameters (communication buffer channel number and connection number)
of the message receive function need to accord with the CPU-03/CPU-04 side settings.
Communication device = Ethernet (218IF)
Note: Similarly, a message receive function with the communication buffer channel number=6 is required.
