<p>PURPOSE:To permit plural workers to independently and repeatedly prohibit an operation and to request release so as to prevent a unit which an another person operation-prohibits from being errorneously operated by writing information concerning plural workers into a storage circuit in correspondence with the scene unit. CONSTITUTION:The workers select the unit to be operation-prohibited/released among the scene units displayed in a display device 11 by display screen touch. An arithmetic unit 14 receives a unit selection command from a touch input device 11a, returns an operation prohibition/release request to the display device 11 and waits for the selection of the workers. When the workers select operation prohibition, the arithmetic unit 14 outputs an input request on information such as the name of the worker, a work number and work date. When the information input of the worker terminates, the arithmetic unit 14 displays information and asks for the recognition of the workers. When recognition terminates, input information is stored in the storage circuit 14a and the operation prohibition state of the unit is displayed, whereby a prohibition command is outputted.</p> |
