Abstract

PURPOSE: To increase the transmission efficiency by installing the timer at the master and slave stations each to ensure the independent error process.
CONSTITUTION: Master station 100 contains timer 105 which starts time counting with transmission of the command signal, and slave station 200 contains timer 204 which starts time counting with normal reception of the command signal respectively. Station 100 detects the fault occurrence at the transmission line to the slave station when timer 105 counts the prscribed time and in case no response signal is received from station 200. And the fault occurrence is detected for the transmission line to the master station when timer 204 counts the prescribed time.
