Edit VLT speed

Hello everyone

I have a small problem which I hope you can help me.
I have a touch panel mp277 from siemens. What I could imagine a dialog box where you can write from 0-50 in value. This is no problem. The problem lies in that this value there even be running a drive with a 4-20mA output. Where 0 = 4mA 50 = 20mA. How do I program this? It should be written in the seventh step
Hope someone can help?

Kind Regards
Anders Larsen

Use Siemens Block FC106 Unscale, you'll find it in

Libraries - TI-S7 Converting Blocks

Many thanks

It works
