Reliable, secure connectivity is central to IIoT and Industrie 4.0, and is the function of the OPC UA protocol. Migration to this technology provides the best in open data transport today and in the years ahead.

Matrikon OPC UA Tunneller helps future-proof your control infrastructure in anticipation of increased utilization of OPC UA. It takes the uncertainty out of ensuring reliable OPC Classic/OPC UA interoperability and cross-network communications. This solution is the right choice to get your OPC Classic-to-Classic connectivity and Classic-to-UA bridging up-and-running quickly and efficiently.


  • Enables seamless OPC data transfer through multiple mediums across geographical locations
  • Addresses problems with using OPC Classic components based on DCOM
  • Eliminates permission issues encountered across domains and workgroups
  • Provides 64-bit support for both client-side and server-side connections
  • Employs an intuitive, user-friendly interface
  • Operates in the familiar Microsoft Windows environment
  • Requires minimal user knowledge of OPC UA
  • Eliminates rip-and-replace of OPC Classic assets

Matrikon OPC UA Tunneller makes OPC data connectivity painless regardless of whether you need to connect between different enterprise levels or across the globe.

The Encryption feature in Matrikon OPC UA Tunneller™ enables it to secure your communications from both inside and outside system attacks by hackers. Users are provided with more control over the security of their OPC systems.

The Data Compression feature of Matrikon OPC UA Tunneller™ allows users to reduce the load on their networks. Data sent over satellite and other per-Megabyte connections can be reduced for significant cost savings. Historical data can be compressed to a size much smaller than the original data, all without any data loss.

Matrikon OPC UA Tunneller™ solves 6 major issues encountered using OPC over DCOM:

1. Cross Domains and Workgroups

Authentication difficulties make DCOM connections across different domains or workgroups extremely difficult or impossible. Leap past this limitation with OPC UA Tunneller. Essentially, if you can ping the PC, you can get to it with Tunneller.

2. DCOM and OPC through firewalls

DCOM uses a wide variety of ports, making it almost impossible to configure a firewall with. Not to mention, DCOM is a prime target for viruses and worms such as Blaster. OPC UA Tunneller lets us firewall our PC’s for maximum security against viruses and worms, yet still allows us all the benefits of OPC.

3. DCOM needs a lot of bandwidth

DCOM works best in environments with low latency and high bandwidth; typical of an office LAN. This causes considerable difficulty when communicating over satellite, modems, radio, and other bandwidth-limited communication types. Matrikon OPC UA Tunneller™ features lossless data compression, which reduces load on networks and saves cost when paying per MB of data.

Test Number of Items Update Rate (sec) Tunneller Plain vs DCOM Tunneller Compressed vs DCOM Tunneller Compressed vs Tunneller Plain
Test1 1000 1 54.84% 12.54% 22.87%
Test2 4000 1 54.93% 12.54% 22.29%

4. Timeouts and Disconnections

Plagued with timeouts? Need recovery faster than the unconfigurable 6 minute timeout that comes with DCOM? Matrikon OPC UA Tunneller™ has configurable timeouts to work best with your network and reconnects to OPC Servers in a fraction of the time.

5. Data Privacy

OPC UA Tunneller now features data stream encryption. "Man in the middle" type of attacks can now be thwarted, because OPC data is not readable without the key. Encryption can be selected from 64, 96, or 128 bit AES. OPC UA Tunneller can also limit client connections from only the IP addresses you define.

6. Easy Configuration

Depending on your system, configuring DCOM just to the point of getting communication can take days! OPC UA Tunneller reduces your integration time to minutes!
  • Install Matrikon OPC UA Tunneller on both the OPC Client and OPC
        Server nodes
  • On the client node, define an IP address or computer name to connect to.
  • Start communicating!
  • Matrikon OPC UA Tunneller allows OPC UA-enabled client applications to communicate with OPC Classic Servers and Clients, as well as OPC UA Servers and vice versa.

    For the past 10 years, Matrikon® OPC UA Tunneller™ has delivered a best-in-class solution to eliminate the majority of OPC Classic connectivity problems via a single, easy-to-use package. With Matrikon OPC UA Tunneller, Matrikon continues this legacy while adding powerful functionality to extend the useful life of your OPC Classic components.
