Document Type and Number:
Japanese Patent JP6363317
Kind Code:
B2
Abstract:
In a control/monitor signal transmission system in which device equipment is connected to a plurality of slave stations that are connected to a master station and that exchange data with the master station, the master station exchanging data with a control unit, the slave stations output a test signal to a connection terminal of the device equipment, and transmit connection information obtained by a determination based on the presence or absence of a state change corresponding to the test signal of a test means with which the slave stations are provided.
