Analog Value Representation for Analog Input Channels
Introduction
The tables in this chapter contain the measured value representations for the
various measuring ranges of the analog input modules. The values in the tables
apply to all modules with the corresponding measuring ranges.
Notes for readers of the tables
Tables 4-8 to 4-9 contain the binary representation of the measured values.
Since the binary representation of the measured values is always the same,
starting at 4-10 these tables only contain the measured values and the units.
