IQAN Serialnumber

IQAN offers a Serialnumber ModuleDiagnostics channel, but its in text format. As far as I know, you can't reformat/put that into a numeric channel, or on the CANbus.

What I would like to do, is sending over a unique hardware number (doesn't necessarily have to be the serial, just as long its "baked" into the IQAN somehow) over CAN. So another (non IQAN) unit notifies whenever hardware was replaced. Ideas?
