At 6, it is determined whether or not the same screen has already been displayed in another OPS.
By adding the client OPS1 that has requested new screen development to the destination of the data transmitted from, the physical address conversion processing of the controller 3 for data collection can be omitted, and the screen development can be accelerated. it can.

More specifically, with regard to the screen development processing of this embodiment, the processing schedule function 16
It has a screen display list that is being displayed on PS1, and among the transmitted screen development instructions, another client OPS1 has already been displayed.
If the corresponding screen is being displayed, a flag indicating that the screen is already being executed is added to the data storage function 11 and the data collection function 12 in order to execute the data processing in the shortest processing time. Each processing function can refer to the flag, create display data by the shortest processing, and return it to the client OPS1. In this manner, in the present embodiment, high-speed screen development of a plurality of clients OPS1 is enabled.

As described above, in the present embodiment, in a system composed of one server OPS2 and many clients OPS1, when the same screen display request is received from a plurality of clients OPS1 at the same time, the client side It has a processing schedule function 16 for grouping request processing.
