The slave station is identified and registered by its station number, data communication is performed based on this registered slave station number, and
Even during normal data communication, the above-mentioned initial communication is performed to an unregistered slave station using the interval between data communication,
The slave stations that were added midway through were also recognized and registered, so that normal data communication could be performed from the next time onwards, allowing initial slave station registration and new station registration by adding slave stations midway through. This eliminates the need for registration errors in slave stations, eliminates the inability to communicate data due to registration errors, and improves the reliability of data communication equipment and simplifies work. It will be done.
