    摘要: 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.

    摘要: An intrinsic barrier device, method and computer program product for isolating a communication channel of an input/output (IO) module from a field device. The intrinsic barrier device includes a front end having a programming input adapted to receive an analog input (AI), analog output (AO), digital input (DI) or digital output (DO) IO type configuration signal. The intrinsic barrier device also includes a processor to process the IO type configuration signal and an associated memory device storing an intrinsic barrier IO type configuration (IBTC) program. The processor is programmed to implement the IBTC program. The processor, responsive to the IO type configuration signal configures the intrinsic barrier device to operate as the AI, AO, DI or DO for supporting communications through the intrinsic barrier device over the communication channel between the IO module and the field device in the AI, AO, DI or DO.

    摘要: A method includes transmitting a first value to a first slave device via a communication bus, where the first value is within a first range of values associated with the first slave device. The method also includes receiving a second value via the communication bus and detecting a fault when the second value is not within the first range of values associated with the first slave device. Detecting the fault could include detecting a decoder fault when the second value is within a second range of values associated with a second slave device. The method may further include detecting a fault when the second value is within the first range of values associated with the first slave device but does not equal the first value or detecting no fault when the second value equals the first value.

    摘要: An apparatus includes at least one first input/output (I/O) module having multiple first I/O channels. Each first I/O channel is configured to provide a communication path. The apparatus also includes a second I/O module having multiple second I/O channels. Each second I/O channel is configured to provide a redundant communication path for one of the first I/O channels. The apparatus is configured to provide the redundant communication paths for only a subset of the first I/O channels. The first I/O channels may include critical I/O channels and non-critical I/O channels, and the apparatus may be configured to provide the redundant communication paths for only the critical I/O channels. The apparatus can be configured to provide the redundant communication paths for the first I/O channels of a single first I/O module or multiple first I/O modules.
