Chapter 8. Communication Functions
8-32
5) Example
The following example uses the above diagram to explain the operation of GM7U main unit.
-The data of the master GM7U main unit uses ADD function to increase %MW0 area, and write the data to the slave station of
theGM7U main unit. The written data in the output contact is read by the master station of GM7U, and is written to the output
contact of the expansion digital I/O module, G7E-DR10A.
