Abstract

PURPOSE:To collect a status at the same time of all nodes with a memory, whose capacity is comparatively small, by storing status information at the time point with the respective nodes by a simultaneous command signal from the center station of a loop. CONSTITUTION:A simultaneous signal receiving circuit of the respective nodes stores the status information at the time point to a temporary storing memory 9 by a simultaneous signal to be sent from a center station 100 to respective nodes 101-10n. Next, a polling frame per node is prepared by a polling signal sending circuit 4 of the center station 100 and sent to all the nodes. On the other hand, when the received polling signal is addressed to the self-node, a polling signal receiving circuit of the respective nodes sends the received polling signal to an information transmitting and receiving control circuit 12. The control circuit 12 reads the status information from the temporary storing memory 9 and a status signal frame is prepared and sent to the center station 100.
