The plugins include functionality to edit and check CN / MN XDD / XDC files against the DS311 V1.2.0 and the DS 301 1.3.0 specification. Another plugin enables the user to generate the object dictionary header file from an XDD / XDC file for the openPOWERLINK (https://goo.gl/Cg77Oi) implementation.
Please note that the validation functionality works properly for Controlled and Managing Node XDD / XDC files.
Please use the update site to install the plugin in your eclipse environment...
