ABSTRACT:
A memory-programmable controller of the multiprocessor type, has both a fast bit processor for processing bit oriented operations and a slower word processor for processing word oriented operations. The bit and word operations are stored in a user program memory by the user. These operations are the program which controls the peripheral process controlled by the controller. The bit processor reads the user program memory and sequentially stops when a word command is recognized. The bit processor furnishes information which the word processor uses as the entry address for a program routine associated with the word command in an operating system memory. This provides freedom in the choice of the word processor and in the design of the bit processor to a high degree.
