HR (read-only) area and digital target 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 the tables below. Some register
structures are presented in separate sections below.
The HR and IR values are unsigned 16-bit integers unless
otherwise specified.
