Abstract

A freely programmable control system is disclosed which includes a computer, a data memory, and a program memory, as well as a program controllable logical network for individual bit processing and an individual bit memory. The disclosed control system operates as an integrated system which utilizes both commands for the computer and separate commands for individual bit processing. Both types of commands are stored in the program memory as an integrated program. During individual bit processing the commands for the individual bit operations are routed from the program memory to the logical network circuit for individual bit processing, and are there executed. Similarly, during computer processing the commands for the computer are transferred directly to the computer and are there executed. The commands for the individual bit processing are kept away from the computer by a switching circuit which operates to supply the computer with a command to increment the computer program counter for each individual bit instruction.
