[etherlab-users] Exposing variables from Beckhoff Embedded PC [SEC=UNCLASSIFIED]

We are integrating a Beckhoff CX9020 embedded PC onto our EtherCAT network. The embedded PC (running TwinCAT of course) does its own thing mainly but we would like to expose several of its inputs to the EtherCAT bus driven by our EtherLab master. We have the data transfer working fine.  However I have to manually add the variable names to the outputs of "ethercat xml" (and "ethercat cstruct"). Does anyone know if there is a way to automatically get these variable names? If not is my only option to modify the embedded PC's SII?
