I am looking for a field PG device. 

We have been using TIA portal V11, V15.1, V17, V18& V19 along with simatic manager.

can you recommend me suitable device that can handle above these.

Hello,

This will be difficult with a PG.

TIA V11 is only approved up to WIN 7.

TIA V15.1 is only approved up to WIN 11 23H2.

The remaining TIA versions are currently approved up to WIN 11 24H2.

Please also refer to the compatibility lists for this.

The hardware requirements can be found here:

In this case, an additional VM is recommended.

Best regards
