Beckhoff’s TF3820 | TwinCAT 3 Machine Learning Server

MC Beckhoff TF3820 TwinCAT Machine Learning Server 1 400

Janaury 27, 2022


Beckhoff offers a solution for machine learning (ML) and deep learning (DL) that is seamlessly integrated in TwinCAT 3. The TF3820 TwinCAT 3 Machine Learning Server is a high-performance execution module (inference engine) for trained ML and DL models.

The inference engine is programmed classically in the PLC. From here, models can be loaded, the running hardware can be configured, and the inference executed. The model runs in an independent process of the operating system. There are almost no restrictions when it comes to the ML and DL models. From clustering models to image classification and object detection, the possibilities in the choice of models are extremely diverse.

The ML and DL models are trained in established frameworks such as PyTorch, TensorFlow or MATLAB®. The information of the learned network is loaded to the inference engine as a description file. The standardized exchange format Open Neural Network Exchange (ONNX) is supported, so that the worlds of automation and data science merge seamlessly.

As far as the design of the ML and DL models is concerned, a wide range of hardware is available. The TwinCAT 3 Machine Learning Server can operate classically in parallel on CPU cores, uses the integrated GPU of the Beckhoff Industrial PCs or can access dedicated GPUs, such as those from NVIDIA.

The TwinCAT 3 Machine Learning Server provides an inference engine with maximum flexibility in terms of models and high performance in terms of hardware. Applications can be found in predictive and prescriptive models, machine vision and robotics. Examples are image-based methods for sorting or evaluating products, for defect classification and defect or product localization as well as calculating gripping positions.

Access Management for Your Plant and Machinery

With PILZ’s “Identification and Access Management” portfolio, they offer you a comprehensive range of products, solutions and software for the implementation of safety as well as security tasks. Below you’ll discover more about potential applications, from simple authentication to complex access permissions, and access management through to safe operating mode selection, maintenance safeguarding and safeguarding of data and networks. Experience safety and security in one system!

This solution ensures that a machine cannot resume operation while people are still in the danger zone. The maintenance safeguarding system “key-in-pocket” is designed for machines with danger zones, which are protected by a safety fence and which staff need to access – robot cells for example. In comparison with conventional lockout-tagout (LOTO) systems, maintenance safeguarding with the key-in-pocket solution is implemented via RFID keys with corresponding permissions and a safe list in the PILZ controllers. As a result, it provides a purely electronic restart protection and makes both mechanical interlocking devices and warning tags redundant.
