Analog Electronic Modules
12.1.2 Analog Value Representation for the Measuring Ranges of the
Analog Input Modules in SIMATIC S7 Format
Introduction
The tables in this section contain the digitized analog values for the measuring
ranges of the analog input modules.
The binary representation of the analog values is always the same, so these tables
only compare the measuring ranges and the units.
