Analog Electronics Modules
14.1.4 Analog Value Representation for the Output Ranges of the
Analog Output Modules in SIMATIC S7 Format
Introduction
The table in this section contains the digitized analog values for the measuring
ranges of the analog output modules.
Since the binary representation of the analog values is always the same, this table
contains only a comparison of the output ranges with the units.
Output Ranges for Current: 0 to 20 mA, 4 to 20 mA
