I am familiar with CANopen communication and also to some degree battery 
charging. The old style open Lead-acid batteries should bubble like home brewn 
mash before they are done.

CiA 309-3 is to access a CANopen device over TCP/IP and as I added it could be 
used to access dictionary of devices connected to Linuxcnc.
