Remote Terminal Units (RTUs) are single board remote data acquisition & control systems that are widely used in Nuclear Reactors for acquiring & controlling various analog and digital plant parameters during all states of plant operation. These systems send digitized data packets over Ethernet to the nearest local control centre. Existing design is based on standard off the shelf discrete components which include Microcontroller, Digital ICs like transceivers, logic gates and decoder, analog ICs like Multiplexer, Op-amp, instrumentation amplifier and filters and Mixed Signal IC like ADC. The design implementation concepts of FPGA and FPAA based RTUs is discussed in this paper where the programmable digital and reconfigurable analog hardware is used for replacing multiple discrete digital/analog components in the design. This has enabled us to design RTUs more compact and immune towards component obsolescence issues, with added advantage of more reliability and reduced power consumption. © 2014 IEEE.
