Users can dynamically read status models according to PackML and the associated variables in their project. Since integration can be programmed fully automatically, manual coordination between machine manufacturers and line integrators is superfluous. The statuses used in the state models and the data points can be adjusted depending on the machine type and manufacturer. The OPC UA communication functions combined with a companion specification enable dynamic data readout and make it possible to define uniform status models in OPC, and configure clients automatically.
The companion specification was created by a cross-company workgroup comprising OPC and OMAC PackML members in order to define a data interface based on OPC UA according to PackML. The specification is freely available to all OPC members and can be downloaded from the website.
