7 PROGRAMMING FOR EXECUTING THE MASTER FUNCTION

7.5 Message Communication Function

This section explains an example of a sequence program created for message
communication.

7.5.1 Example of reading message communication data

An example program in this section performs Get Attribute to node No.3.
For the area enclosed with a dotted line, refer to the manual for the relevant slave node
since the class ID, instance ID, and attribute ID are different depending on the actual
area and the slave node.
