How to convert and corrto signal 4-20mA to 0-20mA
because I have two sensors that are 4-20mA and S7-1200 has only inputs 0-20mA how should I proceed in this case

Hello Martins_Eng,
You can make use of the 0-20mA channel to read the 4-20mA signal also. The value below 4 mA would be displayed as 0.
Like it? Rate it!

Hello Martins_Eng,

Use don't need to convert a 4-20mA signal to 0-20mA. Use the 0-20mA channel to read the 4-20mA signal.

Take a look to the tuturial that I attached to this post (Analog Value Processing).
