An implementation is for one or more hardware-based non-transitory memory devices storing computer-readable instructions which, when executed by the one or more processors disposed in a computing device, cause the computing device to monitor a logic block and a memory block to detect a fault condition, determine a subset of the logic block or the memory block that is impacted by the fault condition, and perform at least one action on the logic block and the memory block.

Self-healing process control system

An industrial automation system employing a mesh topology of input/output allows flexibility in pairing field devices and controllers though the I/O mesh. Field devices can be connected to the geographically closest I/O module channel without regard to the location of the necessary controller. Modular prefabrication and deployment of the I/O modules becomes less complex and less time consuming thereby reducing costs.

I/O mesh architecture for an industrial automation system

A programmable interface circuit includes channel(s) including a digital logic block having terminals for receiving control signals from a process controller block, for providing logic signals, and terminals for receiving processed signal data. An analog logic block includes a current output digital to analog converter (DAC). An output circuit block includes first and second field terminals (S1,S2) and a sense resistor, wherein current from the DAC is coupled to S1 and the sense resistor is coupled to S2. The analog logic block includes a first and a second multi-channel multiplexer (MUX), an operational amplifier, and an analog to digital converter (ADC). The control signals automatically select from signal modes including an analog output (AO) mode, a digital output (DO) mode, an analog input (AI) mode, a digital input (DI) mode, and at least one additional signal mode provided by adding a sub-mode to the AI mode or DI mode.
