5.3.2 Analog Value Representation for Analog Output Channels
Introduction

The tables in this chapter contain the analog value representation for output

channels of the analog output modules. The values in the tables apply to all

modules with the corresponding output ranges.

Notes on How to Read the Tables

Tables 5-31 to 5-33 contain the binary representation of the output values.

Since the binary representation of the output values is always the same, starting at

5-34 these tables only contain the output ranges and the units.

Binary Representation of the Output Ranges

The output ranges shown in Tables 5-31 to 5-33 are defined in two’s complement

representation:
