The Modbus SI FTA supports Modbus RTU protocol and uses either EIA-232 or EIA-422/485 communications, including multidrop configurations. The Allen-Bradley FTA supports DF-1 protocol and uses only EIA-232 communication. The serial interface supports direct digital communications to any qualified, compatible subsystem. Using this scheme, serial data is then made available for all APM, HPM, and EHPM data acquisition and control strategies. Using the 16 available array points, an SI FTA has a nominal capacity of up to: • 8192 Flags (Boolean) or • 256 Reals (Floating Point) or • 512 Integers or • 1024 Characters. The array point values can be displayed at the Universal Station or used as part of advanced control strategies. These values can be configured into APM, HPM, and EHPM control strategies using Digital Composites, Device Points, and Regulatory Points as well as CL programs. Both reads and writes of subsystem data are supported. To assure smooth field integration of a variety of subsystems, subsystem devices with the serial interface are qualified as part of Honeywell’s Multi-Vendor Interface Program. In addition, custom interfaces can be designed to met your specific interfacing requirements. Contact your account manager for more information.
Two versions of the Analog Output IOP are available: one with 8 outputs and one with 16 outputs. Both processors provide the following functions • Readback check of actual output current • Output characterization (5 segment) • Output default action on failure (hold or unpowered) • Modes and associated functions to support Manual loader and DDC control • Software calibration The 8-pt. analog output processor provides separate D/A converters and power regulator per channel for maximum output security. As an option, one-on-one Analog Output processor redundancy (available for both versions) provides even higher control strategy integrity. The 16-pt analog output processor may be used with HART® field devices if the Model MU-THAO11 or MUGHAO11 FTA is selected. These FTAs provide a connector for an external HART subsystem, and incorporate filters to prevent interference between the HART® signals and the TPS system.
