Overview
Beckhoff offers a toolbox consisting of hardware and software components for implementing a Condition Monitoring system that is integrated in the control system. The benefit of the Beckhoff solution is integration into the standard machine control system, thereby avoiding additional subsystems with complex cross communication. Machine control and Condition Monitoring run on the same platform and can be programmed with the same engineering tools, and they both use EtherCAT as common fieldbus system.
The TwinCAT Condition Monitoring Library forms a significant part of the software toolbox. Various mathematical algorithms are available as PLC function blocks.
Product information
The current version of the TwinCAT 3 Condition Monitoring library is available as download: http://www.beckhoff.com/software . The PLC library provides different algorithms for data analysis.
Multi task applications are recommended. The data communication between different tasks and CPU cores are done by the mechanism of the library.
Product components
The TF360x Condition Monitoring product consists of the following components:
- PLC libraries: Tc3_CM.compiled-library, Tc3_CM_Base.compiled-library and Tc3_MultiArray.compiled-library
- Driver: TcCM.sys and TcMultiArray.sys
In addition, the product contains the components of TF3680 TC3 Filter. The TF3600 Condition Monitoring Level 1 license contains the TF3680 license, so that all constituent parts of the TC3 Filter product can be used.
