6.2 Communication with Other MP Series
6.2.4 When the MP2300S Acts as Master (ladder program which uses a MSG-SND function)
6-62
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 equipment (MP2300) side follows:
Message receive function (MSG-RCV)
Required for receiving messages. Message reception is carried out by describing and executing this message
receive function in a ladder program.
In addition, in order to support Read and Write by MP2300S, two message receive functions should be provided.
Here, the input item and parameters (communication buffer channel number and connection number) of the mes-
sage receive function need to accord with the MP2300S side settings.
Note: Similarly, a message receive function with the communication buffer channel number=6 is required.
