Abstract

PURPOSE:To ensure an easy confirmation of transmission, by receiving the transmission signal sent from the center station at a local station and transmitting especially the signal to the next local station synchronizing with the transmission signal to be sent to the next local station when the data of own station is normal. CONSTITUTION:The local unit address with an odd parity given only to the address part and the data obtained by adding the check code to the output data or the double transmission data are sent from the center station 2 to the input/output device of each local station 3 and from the address ''0'' of the local station. The station 3, receiving the transmission signal, takes in and delivers the data when the address data of own station is normal. At the same time the station 3 transfers the field power supply on/off signal plus the check code along with the transmission signal of local station to the station 2 synchronizing with the transmission signal of the next station 3 transmitted from the station 2.
