For the communication between different machines, manufacturer independent information models are required. For woodworking machinery, these information models are based on OPC UA, a communication framework developed and provided by the OPC Foundation. While OPC UA provides the technology for the transfer of information, the definition which information is transferred in which form is defined in Companion Specifications.

This documentation defines a Companion Specification for general information regarding woodworking machines. The intention is that ObjectTypes which can be used for several machines and applications are defined only once.
