Abstract

PURPOSE: To perform control surely and simply by determining TL preparation messages and DV preparation completion messages for reporting operation preparation completion and the configuration and the state of devices at the operation preparation completion time in respect to terminal control units (TC) and devices (DV).
CONSTITUTION: By power on of TC2, it is confirmed in center restoration detection circuit 20 that the center rises, and a TC preparation completion message is generated by message generation circuit 25 and is set to transmission buffer 8. The TC preparation completion message of transmission buffer 8 is transmitted to the center when the TC receives polling. When receiving the TC preparation completion message, the center transmits an initial set message to the TC. The TC analyzes the message received by receiving buffer 9 in message analysis circuit 28, and on-line flag latch 13 is set by the output.
