Customizing Your Monitoring with OPC UA Custom Sensors This section delves into the process of enhancing your PRTG monitoring setup by adding custom OPC UA sensors tailored to the specific needs of your ctrlX CORE systems. The guide outlines the straightforward steps for locating your device in PRTG, accessing the sensor menu, and using the search function to find and select the "OPC UA Custom sensor." The configuration process includes naming the sensor, defining measurement units, and specifying Node IDs from the ctrlX data layer using the UA.TestClient. This customization allows for precise and relevant monitoring, focusing on specific data points essential for your operations. Add Custom OPC UA Sensors Navigate to Your Device: In PRTG, locate the device or go to the device tree where you want to add your custom sensor. You can do this by either selecting the device directly or navigating through the device tree to find the specific location. Open Sensor Menu: Right-click on the desired device to open the small context menu. Here, you will find the option to "Add Sensor". Alternatively, each device has an "Add Sensor" option box available directly, making it easy to start the process without navigating menus. Search for OPC UA Sensors: In the sensor addition menu, use the search bar and type "OPC" to filter for OPC UA-related sensors. From the displayed options, select "OPC UA Custom Sensor" to proceed to the sensor configuration settings. Figure 24: Searching the OPC UA Custom Sensor Configure Your Custom Sensor Sensor Settings: Start by giving your new sensor a meaningful name that reflects its purpose or the data it will monitor. OPC UA specific Settings: Channel Naming: Scroll down to the "OPC UA Specific" settings. You'll see an option for channel naming. Here, you can give each channel a custom name that suits your monitoring needs, such as "CPU Core 0 Load" or "System Memory Usage". Unit Specification: Specify the unit of measurement for each channel (e.g., degrees, GB, KB, %) to ensure clarity in data presentation. Node ID Configuration: To integrate custom OPC sensors within PRTG, it's essential to accurately specify the Node ID for each data point you intend to monitor. Acquiring the Node ID from the ctrlX data layer can be efficiently performed using the UA.TestClient tool. This client is designed for ease of use, particularly with Bosch Rexroth UA Servers, and is optimized for the built-in ctrlX CORE UA Server. UA.TestClient is a test tool that helps you with practical usage in case you are not a UA expert. Refer here for details of how to connect the UA.TestClient to the ctrlX CORE UA Server. After establishing a connection using the UA.TestClient, follow these steps to locate and utilize the specific data for your custom OPC UA sensor in PRTG: Figure 25: UA.TestClient Connected with ctrlX device, browsed Node id for CPU usage Locate Data Point: Within the UA.TestClient, navigate to and select the data point of interest. This action will display all relevant details for that specific node, such as the Node ID, values, and other attributes. Copy Node ID: Carefully copy the desired Node ID. This identifier is crucial for ensuring accurate data monitoring and should be selected based on the data you wish to monitor. Configure OPC UA Custom Sensor: In the PRTG interface, proceed to the OPC UA Custom Sensor settings. Find the field labeled "Node ID" and paste the copied Node ID into this blank space. This step links the sensor to the specific data point on your PLC. Create Channels: Depending on your monitoring requirements, you can create multiple channels within the OPC UA Custom Sensor settings. Each channel can be configured to monitor different data points by repeating the process of copying and pasting the corresponding Node IDs. Figure 26: PRTG OPC UA Custom sensor Channel Configuration Create the Sensor: Once you've configured the sensor settings to your preference, click on "Create" to finalize the sensor addition. This process may take a few seconds. Your Custom Sensor: After creation, the custom sensor will appear in your device tree under the selected device. Double-clicking on the sensor will display all the configured channels and their current values, providing real-time data directly on your PRTG dashboard. Figure 27: PRTG OPC UA Custom CPU sensor with ctrlX CPU Core Channels By following these steps, users can tailor their PRTG dashboards to their specific monitoring requirements, enhancing the visibility and control over their Bosch Rexroth ctrlX CORE PLC operations. Be sure to accompany each step with illustrative images to ensure users can easily follow along and implement these customizations effectively.
