Abstract
PURPOSE:To monitor the state of all terminals within a prescribed time, by sectioning a plurality of terminals into a plurality of blocks, and providing a block controller controlling the blocks. CONSTITUTION:One block is constituted with a plurality of terminals 3 (31-1- 3n-n), the state change in the terminals 3 is monitored with the transmission/ reception of signals with the terminals 3 in the blocks and the result is stored at block controller 2 (21-2n). Each block controller 2 is scanned from a center 1 and the state of all the terminals 3 is grasped by scanning each block controller 2. In this case, addresses are given to the block controller 2 and the terminals 3. The address and data are transferred in the change in the state and operating instruction for collation confirmation, and when an error is detected in the reception signal, re-transmitting processing is made as non-response.
