Representation of analog values
Introduction
The analog values for all measuring ranges that you can use with the analog on-board I/O
are represented in this appendix.
For cross-product information on "analog value processing", refer to the Analog value
processing (http://support.automation.siemens.com/WW/view/en/67989094
) function
manual.
Measured value resolution
Each analog value is entered left aligned into the tags. The bits marked with "x" are set to
"0".
Note
This resolution does not apply to temperature values. The digitalized temperature values are
the result of a conversion in the analog on
-board I/O.
