トローラ。 After level-converting the information signal transmitted from the controlled device to the control signal level by the input level conversion circuit of the input/output device, the arithmetic processing circuit in the programmable controller performs sequence calculation based on the information signal, and then converts the sequence to the control signal level. In a programmable controller that converts an information signal determined by calculation to a transmission signal level by an output level conversion circuit of the input/output device and outputs it to the controlled device, the input signal line from the input/output level conversion circuit is an input connector for detachable connection; a bus driver that transfers input information signals to the arithmetic processing circuit according to instructions from the arithmetic processing circuit via the connector; and an output signal to the output level conversion circuit. It is characterized by comprising an output connector for detachably connecting a line, and a latch circuit that holds an information signal determined by the sequence operation according to instructions from the arithmetic processing circuit and outputs it to the output connector. programmable controller.
