The relationship between the configuration of the input state area 43 and the training screen display information will be described with reference to FIG. The input state area 43 is divided into a real signal input area 43-1 and a training area 43-2, and the training area 43-2 is a copy of the real signal input area 43-1. A plurality of addresses in each area is called a point, and the actual signal point n
Is the n-th address in the actual input state area 43-1 and is also the n-th address in the training area 43-2. Therefore, converting the data of the actual screen display information 42 for training means that the state pointer Sn indicating the on / off state of the monitoring target control device stored at each point in the screen display information 42 is changed to the training area 43-2. Copying to the point BASE + n obtained by adding BASE to each pointer.
