OPC Netlistener

Introduction

In today's industrial automation landscape, network reliability and performance are crucial for seamless operation. The OPC Netlistener is a powerful tool designed to monitor and supervise network loads, applications, and Ethernet errors, providing a transparent and efficient network management solution. In this article, we will delve into the features and benefits of the OPC Netlistener, exploring its capabilities and applications in industrial automation.

What is OPC Netlistener?

The OPC Netlistener is a server that allows supervising device processes (watchdog) and provides the operator with CPU load data as an OPC variable. It also shows the CPU load of the host computer, making it an essential tool for monitoring system performance and detecting potential issues early on. The server sends ICMP (ping) or SNMP-requests to the supervising hosts, presenting these as an OPC-item. Additionally, it supervises cyclical processes on the host to check for program errors.

Key Features of OPC Netlistener

The OPC Netlistener offers a range of features that make it an indispensable tool for network monitoring and management. Some of its key features include:

• Early Detection of Ethernet Errors: The OPC Netlistener provides a transparent Ethernet by detecting errors early, ensuring that your network remains reliable and efficient.
• Supervision of Various Network Loads and Applications: The server supervises multiple network loads and applications, providing a comprehensive view of your network's performance.
• Information on the State of the Network: The OPC Netlistener provides real-time information on the state of your network, enabling you to make informed decisions and take proactive measures to prevent issues.
• Easy Integration into Your HMI through OPC: The OPC Netlistener offers easy integration into your Human-Machine Interface (HMI) through OPC, making it simple to visualize and monitor network performance.
• Option to Program Your Own Network Management Applications in Your SCADA: The OPC Netlistener provides an option to program your own network management applications in your Supervisory Control and Data Acquisition (SCADA) system, giving you complete control over your network management.
• Easy to Use through Known Visualization Software: The OPC Netlistener is easy to use through known visualization software, making it accessible to users with varying levels of technical expertise.

How to Test the OPC Netlistener

To test the OPC Netlistener, you can use the TestClient (SNMPVariableBuilder) included in your scope of delivery or any other OPC-client, such as Matrikon – OPC – Explorer. The SNMPVariableBuilder is a simple MIB-Browser that can generate your OPC-Items with one click. You only have to click on one OID item and copy the built string onto your OPC-Client. You can also test the built variable against the OPC-Server.

Benefits of Using OPC Netlistener

The OPC Netlistener offers numerous benefits to industrial automation users, including:

• Improved Network Reliability: The OPC Netlistener provides a transparent Ethernet, detecting errors early and ensuring that your network remains reliable and efficient.
• Enhanced Network Performance: The server supervises multiple network loads and applications, providing a comprehensive view of your network's performance and enabling you to make informed decisions.
• Increased Productivity: The OPC Netlistener offers easy integration into your HMI through OPC, making it simple to visualize and monitor network performance and increasing productivity.
• Reduced Downtime: The OPC Netlistener provides real-time information on the state of your network, enabling you to take proactive measures to prevent issues and reduce downtime.
