Representation Of Analog Values - Siemens ET 200SP Manual

Representation of analog values

This appendix shows the analog values for all measuring ranges that you can use with the
analog module.
Measured value resolution
The resolution of the analog values differs depending on the analog module and its assigned
parameters.
The table below shows the representation of binary analog values and of the associated
decimal and hexadecimal units of the analog values.
Each analog value is written left aligned to the tags. The bits marked with "x" are set to "0".
