Industrial Automatic Control Systems and Controllers Annotation << Back Direction of Extension of the Functional Facilities of Industrial Controllers under the User Interaction O.L. Akhremchik Features of operation of the user interaction with an operator panel of the industrial controller are considered. The selection of additional channel as a part of the controller is offered. The special mode for the channel tuning is proposed. It is planned that the selected mode and the channel will be used for support of the additional functions of controller connected to estimation of the user action. Analogies and differences of interaction from operations of user keyboard handwriting monitoring in computer systems are specified. The number of errors and the viewing time of technological program in the operation mode are selected as basic coordinates of estimation. Extension of coordinate system of interaction estimation is represented under the distinctions of operator operation in modes of browse and input of controller confi guration. Keywords: interaction, time, user, PLC, regime, properties. Contacts: E-mail: axremchic@mail.ru Pp. 59-64.
