PURPOSE:To accurately record time information without correcting the time information at the time of generating a fault by transferring time setting information between work station interface devices installed in respective stations. CONSTITUTION:The work station 2 of a master station 1 has an absolute timepiece to be the reference time for all stations and generates time information 3. A network monitoring device 4 displays the time of generating an alarm based on the information 3. The work station interface 5 receives the information 3 and transmits time setting information 6 to a slave station 7. On the other hand, the work station interface 8 of the slave station 7 receives the information 6 and gives the work station 9 time setting information 10. The work station 9 sets an inner timepiece based on the information 10 to generate time information 11 and a network monitoring device 12 displays the time of generating the alarm. Consequently, the same time can be set to the inner timepieces of the network monitoring devices of the respective stations. |
