10-2 Communication method

The host computer communicates with each station number one by one.

① The host computer instructs station number/communication contents/memory address/data

etc. of the communicating station as a “command.”

② The “command” receiving station processes this data and returns the result as “response.”

On the computer link, the host computer can communicate with any required station regardless

of whether it is the master or slave station.
