PURPOSE: To reduce kinds of controllers installed in terminal stations greatly and to constitute a system having a greatly large number of freedom, by storing a program for monitoring and controlling equipment in a center device previously, and monitoring and controlling the equipment according to the program.
CONSTITUTION: Port numbers of a microprocessor 4 where constituent elements of each load equipment, etc., are connected respectively are allocated while classified by functions. For example, port numbers IN1∼IN4 are allocated to on-off control over a driving relay 8 and correspond to relay outputs X1∼X4 of data, and other port numbers IN5∼IN8 are allocated to an analog sensor 13 and corresponding to digital data S1∼S4; and port numbers 9∼12 are allocated to a detector 6 for alarm generation and correspond to alarm data A1∼A4, and port numbers IN13∼IN16 are allocated to a terminal information switch 14 and corresponding to ports C1∼C4.
