Abstract: System (200) and method (400) for enabling peer-to-peer communications between controllers (2041, . . . , 204N, 2221, . . . , 222N) of at least two control systems (202, 218). The system (200) include a first control system (FCS) having a first controller (FC) communicatively coupled to a first input/output (I/O) processing module (2121, . . . , 212N) via a first I/O network (2141, . . . , 214N). The first I/O processing module is communicatively coupled to first automation equipment (216). The second control system (SCS) includes a second controller (SC) communicatively coupled to the FC via the first I/O network. The first I/O network provides peer-to-peer communications between the FC and SC. The SC is configured to emulate the first I/O processing module. More particularly, the SC is configured to match an internal I/O configuration with an I/O configuration of the FC.

Abstract: 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.

Abstract: A system for handling data of a process with a primary controller and a redundant controller. The primary controller includes a primary processor that is operable to perform tracking data tasks by using a low speed bus to cooperate with a tracker controller for storage of tracking data in a tracker memory. The primary processor is further operable to perform other tasks by using a high speed bus in cooperation with a primary memory. The second bus has an operating rate considerably higher (for example, a factor of two or more) than that of the first bus.
