OPC Router is a software program that allows you to connect data from various industrial devices and IT/OT systems to each other. All this quickly, automatically and without programming knowledge. In addition, you can see all data flows in a clear visualization.
Collect data, connect systems, perform calculations, compare values and enter results into databases. You can do all this with OPC Router for PLC systems, OPC servers, printers, RFID readers, emails, Excel spreadsheets, databases, cloud systems, MQTT brokers, ERP systems SAP R3, SAP HANA, etc. For installation on a single computer you need a basic module and one or more plug-in modules.
RESTful Plug-In
The REST interface is based on pure web technologies. Many modern applications use the REST protocol for data exchange with other systems.
With the OPC Router and the RESTful plug-in, you can access any system that supports the REST interface. You can send requests (REST Client) to retrieve or modify data and send responses (REST Server) to these requests.
Using the pre-defined REST Trigger, a REST API can be created for each system connected to the OPC Router.


Reading Talk2M cloud data and transferring it to the OPC Router via the REST interface – the optimal solution for report generation
The globally available Talk2M cloud service allows for remote access to Ewon industrial routers and devices connected to them. Apart from remote access, Ewon industrial routers can be used for data acquisition. Using them, you can collect data locally as well as remotely through the Talk2M cloud. The data, having been stored in the Talk2M cloud, can then be read, for example, via the REST interface.
Collecting data from Ewon Flexy 205 routers deployed all over the world, through the Talk2M cloud service, is the perfect solution for system integrators. It enables them to monitor the condition of and collect data about machines and production lines all over the world. As the Talk2M cloud service is available worldwide, system integrators can collect data and generate reports from anywhere.

Video tutorial for the RESTful Plug-in
In this video we explain how to integrate OPC Router into your REST communication. In the first example we query weather data from OpenWeather. In the second example we show you how to configure and test a REST-ful interface on the OPC Router to read order data from a database.
System Requirements
Installation and Update
The OPC Router setup installs the configuration environment, Windows services and all plug-ins in demo mode with a runtime of 2 hours. Licensed plug-ins can only be run without time limitation after entering the license key.
The installation does not include a database system or an OPC server for production use. These components must be installed separately and then connected in the OPC Router configuration.
Computer Performance
OPC Router is a server application, so we recommend running it on suitable hardware. For standard use, we recommend:
- a multi-core processor,
- at least 8 GB RAM,
- SSD storage.
Operating System
For production use, we recommend Microsoft Windows Server operating systems. 64-bit client operating systems can also be used, especially for testing purposes.
Supported operating systems:
- Windows Server 2016 x64
- Windows Server 2019 x64
- Windows Server 2022 x64
- Windows Server 2025 x64
- Windows 10 x64
- Windows 10 IoT x64
- Windows 11 x64
Running in Docker
OPC Router can also be run in a Docker container, for example on an Edge device or a Windows device. The minimum requirements for running OPC Router in a Docker container are:
- 64-bit single-core 600 MHz CPU with AVX support,
- 512 MB RAM,
- 3 GB of free disk space.
.NET 8
OPC Router requires .NET 8. If it is not installed on the system, the OPC Router setup will install it if necessary.
In production environments, we recommend installing .NET 8 manually from Microsoft before updating OPC Router. The .NET installation may require Windows updates, take longer to complete and sometimes require several restarts. To reduce downtime, we recommend uninstalling older .NET versions only after .NET 8 has been installed successfully.
OPC Server
To connect controllers via OPC, an installed and accessible OPC server must be available. OPC Router supports connections via OPC DA 4.0, OPC UA and OPC XML.
The corresponding OPC plug-in is required for communication with an OPC server.
Database Server and Data Sources
Database servers are not part of the OPC Router installation. If you want to connect them to OPC Router, they must be installed and made accessible separately.
OPC Router supports connections to the following database systems and interfaces:
- Microsoft SQL Server
- Oracle
- MySQL
- SAP HANA
- OLE DB
- systems accessible via ODBC
The following databases, data sources or files can also be connected:
- MS Access
- SQLite
- dBase
- InfluxDB
- MongoDB
- XML files
Plug-ins for database communication are not included in the Basic license. The appropriate plug-in must be selected for the specific type of database connection.
Oracle Database Connection
To connect to an Oracle database, Oracle Instant Client (ODAC) must be installed.
SAP Plug-in
The SAP Plug-in supports SAP systems version 4.0b and higher. SAP Logon Pad or the librfc32.dll library must be installed on the computer running OPC Router.
To use SAP NetWeaver, SAP NetWeaver RFC SDK must be installed.
The SAP Plug-in is a separately licensed module and is not included in the Basic license.

New features in the OPC Router 5.1 data hub
The new version of OPC Router 5 brings some big changes. The biggest change is the user interface, which brings the user more comfort when working with the program and the ability to work in Linux, macOS, etc. There are also new options for creating user accounts, improvements in application performance optimization and many other improvements.
Highlighted items are mandatory.
