Overview2OverviewThe TwinCAT Function TC3 IoT Data Agent provides bi-directional connectivity to different cloud services. Itis a gateway application that can be installed either on the controller or on a gateway computer. TheTC3 IoT Data Agent can be configured to connect different data sources with each other, e.g. aTwinCAT 3 PLC (ADS) and a MQTT Message Broker. In addition, public cloud services can be used, forexample AWS IoT and Microsoft Azure IoT Hub. TC3 IoT Data Agent includes an integrated OPC UA client,which allows to connect third-party devices to the cloud. Legacy applications running TwinCAT 2 can beconnected by running TC3 IoT Data Agent on a gateway computer and by using ADS or OPC UAconnectivity to the TwinCAT 2 system.When sending or receiving data, users can select from a variety of different data formats, ranging fromefficient binary formats to ASCII-based JSON formats. This allows the use of the TC3 IoT Data Agent indifferent scenarios, e.g. to connect devices to TwinCAT Analytics.Different communication patterns can be configured to optimize traffic congestion, e.g. polling or on-changepatterns.ComponentsTC3 IoT Data Agent consists of the following components: Core application: background service that provides the logic Configurator: graphical tool to create/edit and deploy a configuration for the core applicationTwinCAT 3 IoT Data Agent can be installed and used in different setup scenarios, e.g. directly on thecontroller or on a gateway computer (see Setup scenarios [} 8]).TF6720Version: 1.47

It can either be installed and useddirectly on the industrial controller (see System Requirements [} 8]) or on a gateway computer thataggregates multiple devices or connects to legacy applications like TwinCAT 2. Each setup scenario has itsadvantages and disadvantages, depending on the system environment and project for which theTC3 IoT Data Agent is to be used.TC3 IoT Data Agent running on the controllerThis is the default scenario. TC3 IoT Data Agent is installed directly on a Beckhoff industrial controller (IPCor Embedded-PC) and connects only to the TwinCAT runtime on that system. This is the preferred scenariobecause every IoT device should have an own connection to the cloud service, although gateway scenariosare possible and sometimes also necessary.8Version: 1.4TF6720
InstallationTC3 IoT Data Agent running on a gateway computerIn this scenario, TC3 IoT Data Agent is installed on a gateway computer that aggregates multiple devices,e.g. to connect to existing machine applications in a retrofit scenario. This scenario can also be combinedwith other TwinCAT Functions, e.g. a TwinCAT OPC UA Server, which is also able to aggregate multipleTwinCAT runtimes. A typical hardware device for such a setup scenario is a Beckhoff C6015 Ultra-CompactIndustrial-PC.Be aware that the network traffic between the TC3 IoT Data Agent and the underlying devices can be veryhigh in this setup scenario because the TC3 IoT Data Agent needs to sample symbols from every connectedruntime and this sampling is being done via the network.TF6720Version: 1.49
InstallationTC3 IoT Data Agent configuratorThe TC3 IoT Data Agent configurator [} 35] is a graphical configuration tool. It can be installed on the samecomputer that executes the TC3 IoT Data Agent core application or on an engineering computer to remotelycreate/edit and deploy the configuration across the network.3.3InstallationThe following section describes how to install the TwinCAT 3 Function for Windows-based operatingsystems.ü The TwinCAT 3 Function setup file was downloaded from the Beckhoff website.1. Run the setup file as administrator. To do this, select the command Run as administrator in the contextmenu of the file.ð The installation dialog opens.10Version: 1.4TF6720
Installation2. Accept the end user licensing agreement and click Next.3. Enter your user data.TF6720Version: 1.411
Installation4. If you want to install the full version of the TwinCAT 3 Function, select Complete as installation type. Ifyou want to install the TwinCAT 3 Function components separately, select Custom.5. Select Next, then Install to start the installation.ð A dialog box informs you that the TwinCAT system must be stopped to proceed with the installation.12Version: 1.4TF6720
Installation6. Confirm the dialog with Yes.7. Select Finish to exit the setup.ð The TwinCAT 3 Function has been successfully installed and can be licensed (see Licensing [} 13]).3.4LicensingThe TwinCAT 3 function can be activated as a full version or as a 7-day test version. Both license types canbe activated via the TwinCAT 3 development environment (XAE).Licensing the full version of a TwinCAT 3 FunctionA description of the procedure to license a full version can be found in the Beckhoff Information System inthe documentation "TwinCAT 3 Licensing".Licensing the 7-day test version of a TwinCAT 3 FunctionA 7-day test version cannot be enabled for a TwinCAT 3 license dongle.1. Start the TwinCAT 3 development environment (XAE).2. Open an existing TwinCAT 3 project or create a new project.TF6720Version: 1.413
Installation3. If you want to activate the license for a remote device, set the desired target system. To do this, selectthe target system from the Choose Target System drop-down list in the toolbar.ð The licensing settings always refer to the selected target system. When the project is activated onthe target system, the corresponding TwinCAT 3 licenses are automatically copied to this system.4. In the Solution Explorer, double-click License in the SYSTEM subtree.ð The TwinCAT 3 license manager opens.5. Open the Manage Licenses tab. In the Add License column, check the check box for the license youwant to add to your project (e.g. "TF6420: TC3 Database Server").6. Open the Order Information (Runtime) tab.ð In the tabular overview of licenses, the previously selected license is displayed with the status“missing”.14Version: 1.4TF6720
Installation7. Click 7-Day Trial License. to activate the 7-day trial license.ð A dialog box opens, prompting you to enter the security code displayed in the dialog.8. Enter the code exactly as it is displayed and confirm the entry.9. Confirm the subsequent dialog, which indicates the successful activation.ð In the tabular overview of licenses, the license status now indicates the expiry date of the license.10. Restart the TwinCAT system.ð The 7-day trial version is enabled.3.5Licensing informationLicensing of TC3 IoT Data Agent is based on so-called “Gate packs”. Each ADS device or OPC UA servernamespace to which the TC3 IoT Data Agent connects is considered to be a “Gate”. TheTC3 IoT Data Agent base license “TF6720” already includes an amount of four Gates. Additional Gates canbe acquired
TC3 IoT Data Agent can be configured to connect different data sources with each other, e.g. a TwinCAT 3 PLC (ADS) and a MQTT Message Broker. In addition, public cloud services can be used, for example AWS IoT and Microsoft Azure IoT Hub. TC3 IoT Data Agent includes an integrated OPC UA client,
