Abstract
A setting display apparatus for managing a programmable controller is arranged to enable a display program to be designed easily and efficiently and to reduce the memory capacity for the program. A display program is divided into a frame flow program and a frame forming program, which can be programmed independently each other. The frame forming program has the function of forming a basic frame including information on the size, position, etc., of letters and figures such that importance is attached to the appearance. Addresses of data displayed on the basic frame corresponds to addresses in a reception buffer memory. The frame flow program has the functions of designating addresses in a device memory of the programmable controller as direct addresses of the displayed data and designating a frame change condition and a shift destination frame number. The frame flow program is characterized by its adherence to mechanical control.
