PRTG makes PLC monitoring as easy as it gets
Custom alerts and data visualization let you quickly identify and prevent PLC hardware health and performance issues.
Control the controllers & keep your industrial operations flowing
PLCs are the backbone of industrial automation. As they operate in real time, meaning they process input signals and execute control functions with minimal delay, they are crucial for time-sensitive industrial processes.
But what happens if you have issues with PLCs – if they stop working or are lacking in performance? Production processes come to a standstill, unintended operations occur, machinery breaks down – and costs pile up to uncontrollable heights.
This is where Paessler PRTG comes into play. Our PLC monitoring solution keeps an eye on your programmable logic controllers as well as your entire OT environment round the clock, making sure that issues are detected before they become business critical and costly.
5 reasons why to choose PRTG as your PLC monitoring tool
Detect malfunctions in real time
Continuously check inputs, outputs, and the PLC's internal state to immediately identify issues such as sensor failures, communication errors, or programming bugs.
With PRTG, you can detect faults or anomalies in the control system early on, even before potential issues escalate into major problems. This way, you can ensure that your industrial processes stay online, stable, and reliable.
Enhance performance & productivity
By monitoring PLCs with PRTG, you can optimize production processes, identify bottlenecks, and reduce inefficiencies.
Get comprehensive visibility into the performance of your PLCs and the overall health of your industrial network with PRTG’s easy-to-read dashboards and maps, and fine-tune operations based on real-time data and historical performance trends.
Save costs with predictive maintenance
Monitor your PLCs to introduce predictive maintenance strategies and predict when equipment is likely to fail or require maintenance. This helps you to significantly reduce maintenance costs by preventing unplanned downtime and extending the lifespan of equipment.
With PRTG, you can also analyze trends and patterns in PLC data to optimize energy consumption and save even more resources and costs.
Comply with governmental regulations
In industries that have regulatory requirements for monitoring and reporting on equipment performance and environmental conditions, PRTG is the perfect tool to collect and analyze PLC monitoring data and ensure compliance.
Use PRTG’s historical data logging capabilities to prepare the reports required for audits and other regulatory inspections.
Scale to monitor thousands of devices
PRTG is designed to scale effortlessly to meet the growing monitoring needs of industrial environments, and is capable of monitoring thousands of devices simultaneously.
Whether you have a small-scale operation with a few PLCs or a large enterprise environment with extensive industrial infrastructure, PRTG can monitor it – without compromising performance.
What PLC monitoring looks like in PRTG
Diagnose network issues by continuously tracking the health and performance of your programmable logic controllers next to other industrial IT and IoT components like HMIs or SCADA systems. Show I/O states, hardware parameters, PLC program functionality, bandwidth, environmental values, network traffic, and other key metrics in real time. Visualize monitoring data in clear graphs and dashboards to identify problems more easily. Gain the overview you need to troubleshoot all kinds of issues with your PLCs.

How PLC monitoring with PRTG works
Support for various industrial protocols
PRTG's comprehensive protocol support ensures compatibility with a wide range of industrial devices and systems.
Whether your PLCs communicate via OPC UA, Modbus TCP/IP, Modbus RTU Serial, MQTT, or other industry-standard protocols over gateways, PRTG can seamlessly integrate and gather essential data for monitoring purposes.
Customizable alerts and notifications
Configure alerts based on predefined conditions or thresholds so that PRTG can notify you via SMS, email, in-app push notification, and other methods as soon as a warning or error threshold is breached.
With our product extension Paessler PRTG OPC UA Server, you can even integrate alarms from PRTG in your supervisory and control system using OPC UA.
Individual dashboards for different users
PRTG enhances your monitoring even further with highly customizable dashboards and maps that give you visual real-time insights into the performance and status of your PLCs and your entire industrial infrastructure.
Use our drag-and-drop editor to quickly create personalized views of your PLC health, and publish them internally or over the Internet.
