4.3.2 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 for readers of the tables
Tables 4-32 to 4-33 contain the binary representation of the output values.
Since the binary representation of the output values is always the same, starting at
4-34 these tables only contain the output ranges and the units.
Output ranges for the SM 334; AI 4/AO 2 8/8 bits
The analog input/output module SM 334; AI 4/AO 2 x 8/8 bits has output ranges
from 0 to 10 V and from 0 to 20 mA. Unlike the other analog modules, the SM 334
has a lower resolution, however. Please not that the SM 334; AI 4/AO 2 x 8/8 bits
with product status 1 does not have overranges.
Binary representation of the output ranges
The output ranges shown in Tables 4-32 to 4-33 are defined in two’s complement
representation:
