Abstract

A general-purpose functional circuit for a programmable controller, comprising: an external connector which is connected to an external appliance to be controlled; an interconnecting connector which is connected to at least a CPU unit of the programmable controller; and an arithmetic processing member which has at least a function of transmitting to and receiving from the external appliance connected to the arithmetic processing member through the external connector, signals and performing a logical operation based on an external signal received from the external appliance so as to transmit to the CPU unit via the interconnecting connector, a logical operation signal corresponding to a result of the logical operation; wherein the CPU unit includes a CPU for executing a sequence program.
