This document defines a Companion Specification for Wireless Machine Tool Peripherals (WMTP) using OPC UA constructs to exchange process parameters wireless between components and software systems, such as MES-Systems, mobile devices, etc.

The process parameters are recorded by sensors on the components and are used for process monitoring.

The aim of the specification is to define all relevant process parameters for the use of wireless machine tool peripherals in alignment to the Bluetooth Industial Measurement Devices standard for WMTP (see 2). Only the industry-specific (manufacturer-independent) process values are defined - company-specific process values are not taken into account in the specification.

The first version of the OPC UA Companion Specification for WMTP applies to driven tool units, static tool holders and angle heads. Other sensor-equipped machine peripherals can be modelled on the basis of this Companion Specification, but will probably have to be extended by certain parameters.
