ABSTRACT:
A programmable controller (PC) which converts PC instructions directly into targeted CPU instructions, not into a macroprogram format, and stores them as an execution file. The PC stores restoration information for ladder display together with the CPU instructions, whereby the number of program steps to be executed is reduced and a ladder display can be provided. The PC also converts PC instructions written in the ladder language into restoration information restorable to the ladder language and generates them as a main processing restoration information file, then converts the PC instructions directly into targeted CPU instructions, not into a macroprogram format, on the basis of the restoration information file, and stores them as an execution file independently of the main processing restoration information file. Also, the execution file for sequence processing is separated from the main processing restoration information file for ladder display, ensuring that processing can be performed much faster without needing to judge whether a step is an execution instruction or display information. The PC incorporates conversion programs and conversion tables for generating finally required CPU instructions, whereby sequence programs can be developed in an environment where there is no computer for sequence program development. The use of such tables and programs permits function change and function addition to be made to the stored conversion tables using an accessory CRT/keyboard so that specifications can be changed as required.
