Abstract

See full text

In a system including a master station, slave stations, and a loop communication path for connecting the master and slave stations, the master station measures for each of the slave stations a transmission lag time from transmission of a communication frame in a forward direction through a loop communication channel in the master station to reception of the communication frame returned in a backward direction from the slave station, and calculates timer correction times for the slave stations based on both the transmission lag times measured for the slave stations and delay time information representing delay times caused by communication frame processing in the slave stations. Each of the slave stations includes a transmission/reception switch which switches a communication frame transmitting/receiving direction between the forward and backward directions in the loop communication channel, to allow timer synchronization in the loop communication path formed by the single communication channel.
