Chapter 8 Communication Function

8-58

8.2.4 Example of Use 1

This example is supposed that there’ s a communication between MK80S’ s by the user-defined protocol. The system configuration is as

follows and the cable is the same with the one of 1:1 dedicated protocol communication.

The data in M area of the master station is sent to the slave station and the slave station saves the received data in M area

outputs as direct variable, and sends the data back to the master. This process repeats between the master and the slave.

K7 base unit
(Slave: Station No. 1)

K7 base unit
(Master: Station no. 0)

1:1 dedicated protocolcommunication between K7’ s
