Measured value resolution
The following table shows the representation of the binary analog values and the corresponding
decimal or hexadecimal representation of the units of the analog values.
The following table shows the resolutions 11-, 12-, 13- and 15-bit + sign. Each analog value is
entered left-justified in the ACCU. The bits marked with "x" are set to "0".

Measuring ranges of the analog input modules in S7 format

Introduction
The tables in this section contain the digitalized analog values for the measuring ranges of the
analog input modules.
As the binary representation of the analog values is always the same, these tables only contain
the comparison of the measuring ranges to the units.
