<p>PURPOSE:To smoothly perform maintenance work at a site by arranging a connection terminal device connected from a controller to a transmission line in the neighborhood of each plant equipment and connecting a console to an arbitrary connection terminal device when the operating information of the plant equipment is referred or the operation of the plant equipment is controlled. CONSTITUTION:A worker requests to collect the operating information of the plant equipment 4 to the controller 1 by connecting the console 8 to the arbitrary connection terminal device 6 arranged in a plant factory and performing an input operation from the keyboard 10 of the console 8. The controller 1 transmits the operating information of the plant equipment 4 to the console 8 as response information. The console 8 displays a picture corresponding to the position of the keyboard 10 to which the input operation of the response information is performed. When the operation of a specific plant equipment is controlled, operation control is commanded to the controller 1 by performing the input operation from a designated keyboard 10 being picture-displayed by the response information. In such a way, it is possible to perform the maintenance operation control of each plant equipment from the site.</p> |
