Representation Of Analog Values - Siemens SIMATIC ET 200SP Manual

Representation of analog values

This appendix shows the analog values for all measuring ranges supported by the analog
input module AI 8xRTD/TC 2-wire HF.
Measured value resolution
The resolution of the analog values differs depending on the analog module and its
parameter assignment.
Each analog value is written left aligned to the tags. The bits marked with "x" are set to "0".
Note
Temperature values
The digitized temperature values are the result of a conversion in the analog module.
The following resolution therefore does not apply to temperature values.
