SAFETY DISPLAYING APPARATUS USING MICROPROCESSOR, ESPECIALLY DISPLAYING THE STATE OF SWITCH OPERATED BY USER

摘要

PURPOSE: A safety displaying apparatus using a microprocessor is provided to prevent process delay and facility damage. CONSTITUTION: A local device(20) is operated by receiving electricity. An operation unit comprises a switch controlling the supply of power to the local apparatus. A micom(31) has an input port(32) connected to the operation unit and outputs a control signal corresponding to an operation signal inputted through the input port. A display unit(34) receives the control signal from the micom and displays it to a worker. And a microprocessor(30) has an output port(33) connected to the local device in order to transmit the control signal from the micom to the local device.
