PRTG: the all-in-one monitoring solution for IT/OT environments

iOPC UA stands for OPC Unified Architecture. It is an extensible, platform-independent standard that enables the secure exchange of information in industrial systems.

In the context of a converged IT (information technology) and OT (operational technology) setup, OPC UA data can also be used to enhance the overall capabilities of an all-in-one monitoring system like PRTG.

OPC UA is a platform-independent communication framework that runs on any software platform like Windows, Linux, Mac, or Android. From simple, embedded controllers to massive cloud infrastructure. It is equally suited for use on premises, inside a closed network or to establish connectivity to a cloud platform via the internet. Security is baked into the protocol for access control, authentication, and encryption. Because of its flexibility, OPC UA has been widely adopted in industries like automotive, food and beverage, oil and gas, energy and utilities, packaging, and building automation. PRTG offers two built-in OPC UA sensors:

 OPC UA Server Status sensor

 OPC UA Custom sensor (experimental*)

 

 

The advantages of device monitoring
using OPC UA with PRTG

The ability of PRTG Network Monitor to monitor devices using OPC UA, Modbus, MQTT and more means that it is an all-in-one monitoring
solution that can combine the IT and OT worlds in one single overview.

 

 

Easy OT monitoring

Monitoring does not have to be complicated. With the OPC UA sensors included in PRTG, you can monitor your OT devices without much configuration effort by providing a user-centric GUI to simply add devices, define notifications and create fully customized dashboards. This way, you easily get an overview of your whole plant!

One overview

In industrial IT environments, many OT devices cannot be monitored with traditional IT monitoring methods or protocols. However, these two worlds are becoming more and more convergent. PRTG combines these two worlds giving you over 20 years of IT monitoring experience and widely used industry protocols like OPC UA, Modbus, and MQTT.

Predictive maintenance

When monitoring OT components, one of the most important goals is predictive maintenance. Prevent malfunctions and failures to avoid that production lines stop and high costs are incurred. OPC UA monitoring with PRTG reliably informs you about the state of the various components of your production line.

 

 

 

 

IT/OT convergence with PRTG Network Monitor

PRTG Network Monitor is an excellent IT monitoring solution that combines a wide scope of features with great usability and maximum flexibility. In addition to out-of-the-box support for all common IT standards, PRTG provides a RESTful API as well as OPC UA, MQTT, and Modbus support for easy plant integration. In addition, PRTG supports monitoring for IoT devices, environmental metrics, and other IT equipment and applications that do not use common standards.

OPC UA – how does it work?
 

OPC UA enables access to machines, devices, and other systems

  • OPC UA server: The OPC UA server is the basis of OPC communication. It is a software program that implements the OPC standard and thus provides the standardized OPC UA interfaces to the outside world. The proprietary communication protocol for the manufacturer's control is implemented inside. OPC UA servers are provided by various parties.

 

  • OPC UA client: The OPC UA client is the logical counterpart to the OPC UA server. The OPC UA client can be connected to the OPC UA server and read out the data provided by the server. Since the OPC UA servers implement the specified interfaces of the OPC UA standard, each client can access any OPC UA server and exchange data with the server in the same way.
 

 

 

What is OPC UA?

OPC UA (short for Open Platform Communications Unified Architecture) is a data exchange standard for industrial communication (machine-to-machine or PC-to-machine communication). The open interface standard is independent of the manufacturer or system supplier of the application, the programming language in which the respective software was programmed and the operating system on which the application works.

The OPC UA sensors
and what they monitor
 

iWhat is a sensor?

In PRTG, “sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, e.g. the traffic of a switch port, the CPU load of a server, the free space of a disk drive. On average you need about 5-10 sensors per device or one sensor per switch port.

Modbus TCP Custom Sensor

OPC UA Server Status sensor

The OPC UA Server Status sensor monitors status, uptime, and diagnostic information of your OPC UA server. With this new sensor type, you can ensure your devices are available via OPC UA and that your production processes run flawlessly.

 

Modbus TCP Custom Sensor

OPC UA Custom sensor (experimental*)

The OPC UA Custom sensor monitors up to five numeric values returned by specific OPC UA node IDs. With this sensor type, you can retrieve information such as the PLC state, when a battery needs to be replaced, device failure, and system-specific error states.

 

PRTG sensors for everything else

Many other sensors to monitor everything in your IT environment

PRTG provides built-in monitoring for network devices, servers, storage, applications, and much more... Everything is included!

*OPC UA Custom sensors are a part of the experimental features in PRTG. You can now enable experimental sensors to test the most recent developments from our sensor team. Read here for how to enable and use experimental sensors.

These two sensors enable you to monitor OPC UA servers as well as individual values of up to 5 nodes. The operating methods and the available settings can change in the future.

 

 

 

Keep industrial monitoring
professional with PRTG

IIoT, Industry 4.0, M2M – the digitalization of production is currently taking place and has become a decisive factor in remaining competitive in a global market. Historically separated production facilities and machines require access to the internet for logistics, predictive maintenance, and customer-specific production. These requirements call for integrated communication, which is only possible with traditional IT. IT/OT convergence, the fusion of production and classic IT, is the result. It is essential for preventing risks, eliminating obstacles, and implementing new processes.
