This is not supported with AO815, you cannot get HART Values into the Controller directly.

As far as i know you can do it with other Hardware, S900 I/O or with the "IOCommLib" for Profinet CI871.

while you can't "configure" through the HART variables the AO815 does support HART, meaning you can read up to 4 variables off that analog channel. HART variables will need to be setup in the device accordingly. ex map the feedback to the Primary Variable to read actual valve postion on HART var1. The HART variables would be found in your Hardware IO
