摘要： A network system is formed with a parent station and programmable controllers and a programmable display devices serving as child stations connected to a single general-purpose serial communication circuit. Whichever child station received the token from the parent station outputs a command. Data are exchanged between the programmable display device and any of the programmable controllers by command-response communication. Data are exchanged among the programmable controllers by data link operations.
