ABSTRACT:
An industrial control system is disclosed in which various on/off or other binary functions of an industrial process are each controlled by a separate single board computer. Each single board computer is provided with a simplified system whereby the user can interconnect a logic system between input ports and output ports of the computer to control the setting of the binary data at the output ports in accordance with the selected logic system in response to the data applied to the input ports with the output ports being connected to control the on/off and binary functions in the system. The logic functions are implemented in each single board computer by use of an applications program and a patch panel program. In the applications program, the system responds to input data in a flag memory and sets output flags in the flag memory in accordance with each possible logic function that might be used in the system. In the patch panel portion of the program, the input flags are set and the data at the I/O ports are set in accordance with connection specified by the storing of specific addresses in a patch panel memory.
