Can WinCC OA automatically set exponent prefixes?

Hi,

I am wondering if WinCC OA has any built in functionality that would "convert" a value stored in the datapoint with a defined unit as follows, without me needing to write code for it:
- Value: 0.0012345 A
- Value to be displayed: 1.2345 mA

Thanks for your help and BR,
Matevž

There is no automatic conversion if a value shall be displayed with a different unit.
When the PLC is sending you the value in A (ampere) and you want to use it as mA (milli ampere) in WinCC OA you can do a message conversion in the driver by configuring the _msg_conv config.
