<p>PURPOSE:To easily control a control program by using the same screen of a display device to perform the program monitor, the program tuning and the display of trend graphs of data respectively. CONSTITUTION:A display screen 1-1 is divided into three parts, i.e., a program monitor screen 1a-1, a program tuning screen 1b-1, and a data trend graph screen 1c-1. Then a request is given to a programming device for display of the screen 1a-1 together with requests for display of the screens 1b-1 and 1c-1. In such a way, those three displays are carried out through the same screen and therefore a control program is easily controlled.</p> |
