1. In a programmable process control system of the type comprising a multiple bit computer which comprises a program counter, a data memory coupled to the computer, and a program memory which stores a plurality of computer commands, the improvement comprising: a program controllable logical network comprising means for providing individual bit processing of individual bit information; a bit memory coupled to the logical network for storing said individual bit information; a plurality of commands for the bit processing means stored in the program memory, said computer commands and said commands for the bit processing means stored in the program memory as an integrated program for the process control system; and means for interconnecting the program memory, the computer, and the logical network to form an integrated process control system, said interconnecting means comprising: first means, responsive to the program counter, for directing the plurality of commands for the bit processing means from the program memory to the logical network for execution by the bit processing means; second means, responsive to the program counter, for directing the plurality of computer commands from the program memory to the computer for execution by the computer; switching means for isolating the computer from the plurality of commands for the bit processing means; and means for supplying to the computer a computer command for incrementing the program counter in response to each of the plurality of commands for the bit processing means from which the computer is isolated, such that the command reading time of the computer is preserved during the execution of commands by the individual bit processing means.
