1. An electronic digital process controller for controlling processes of the type utilizing the processing of input signals including one or more analog input signals in order to derive one or more output control signals for controlling one or more process control devices, and controller comprising: input means for coupling one or more input signals from one or more process sensing devices to a computer, said input means including one or more terminals for receiving analog input signals and one or more paths for coupling said analog input signals to a computer; coupled to said input means, an electronic digital computer for receiving said input signals from said input means and processing said input signals to derive one or more process control signals for controlling said process, said computer being programmed to simulate the functions of one or more analog process control blocks; output means for coupling said computer to one or more process control devices, said output means including one or more output paths for coupling said process control signals to said process control devices and one or more terminals for connecting said paths to said process control devices; and a process operator's panel coupled to said computer, said panel including: a. means for selecting each of said one or more analog input signals for processing by said computer. b. means for selecting each of said one or more analog process control blocks for processing a selected analog input signal; and c. means for selecting each of said one or more process control signals and each of said one or more output paths whereby a selected process control signal is directed to a selected output terminal.
