Feeder Protection Relay
Technical Reference Manual
(read-only) area and digital indication values from either the DI or coil (read-only)
area. It is also possible to read the status of the DIs as packed 16-bit registers from
both the IR and the HR area.
Consequently, all monitoring data can be read as consecutive blocks of data from the
IR or HR area.
The register and bit addresses are presented in table 4.1.15.2-5. Some register
structures are presented in separate sections below.
Note!
The HR and IR values are unsigned 16-bit integers unless otherwise specified.
