Representation Of Analog Values - Siemens SIMATIC S7-1500 Manual

Representation of analog values

Introduction
This section shows the analog values for all measuring ranges supported by the
AI 4xU/I/RTD/TC ST analog module.
Measured value resolution
Each analog value is written left aligned to 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 module.
