摘要:
An intrinsic barrier device (124), method and computer program product for isolating a communication channel (110) of an input/output (IO) module (122) from a field device (142). The intrinsic barrier device includes a front end (305) having a programming input (130) adapted to receive an analog input (AI), analog output (AO), digital input (DI) or digital output (DO) IO type configuration signal (134). The intrinsic barrier device also includes a processor (340) to process the IO type configuration signal and an associated memory device (342) storing an intrinsic barrier IO type configuration (IBTC) program (520). The processor is programmed to implement the IBTC program. The processor, responsive to the IO type configuration signal configures (608) 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.
