PM860A is not compatible with firmware 0.44 it's supported from 800xA 3.1 SP2.
You can only use PM860 non A version with that old firmware. You can get the controller working again with flash trough compact flash but only with supported firmware. (3.1 SP2 or newer). Search for document "AC 800M - Renewed PM851A, PM856A, PM860A" 3BSE068694 for more information.

Procedure is a little bit tricky - load the 5.1 version of FW, set the IP address, load the old FW version (by means of open of BIN file)
