The RE_ 54_ terminal is based on a multiprocessor environment that increases
performance. Digital signal processing combined with a powerful CPU and
distributed I/O handling facilitates parallel operations and improves response times
and accuracy. The HMI including an LCD display with different views makes the
local use of RE_ 54_ safe and easy. The HMI instructs the user how to proceed.
The RE_ 54_ terminal is part of the ABB substation automation system and extends
the functionality and flexibility of the concept further. This is possible due to the
modern technology applied both in hardware and software solutions.
