I/O Processors, along with Field Termination Assemblies (FTAs), perform input and output scanning and processing on all field I/O. A redundant I/O Link is standard for added security. Optionally High Level Analog Input, Smart Transmitter Interface, and Analog Output processors can be redundant. I/O processing is performed separately from control processing functions so that I/O scan rates are completely independent of I/O quantity, controller loading, processing, and alarming. This partitioning of functions allows more efficient use of Advanced Control Processor capability and provides for future I/O expansion.
Any mix of the above I/O processors can be selected for an APM. This can be any combination of single and/or redundant (HLAI, STI, and AO) pairs, up to a total of 40. Even with the maximum complement of 80 physical IOPs, there is no impact on control or communication performance. In a redundant configuration, control automatically transfers to the backup I/O processor during board replacement.
While a separate Field Termination Assembly of a given type is required to handle varying field wiring signal levels, identical I/O Processors can be used. This I/O approach simplifies system hardware selection and minimizes spare parts requirements. For example, there is one Digital Input Processor that can handle 24 Vdc, 120 Vac, or 240 Vac, depending on the FTA selected.
