MatrikonOPC Tunneller 3.0 (now with encryption and data compression) provides an easy, reliable and secure way to communicate between networked computers. It does away with the headaches typically associated with DCOM configuration. No longer are different protocols, security settings or locations a factor when sharing data between computers. This is achieved by simply installing MatrikonOPC Tunneller on the OPC client and OPC server nodes and then telling the Tunneller client where the Tunneller server exists.

If you require redundancy in your tunnelled connections, MatrikonOPC's Redundancy Broker can be used along with OPC Tunneller. The new Encryption feature in MatrikonOPC Tunneller 3.0 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 the new MatrikonOPC Tunneller enables 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. MatrikonOPC 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 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 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. MatrikonOPC Tunneller features lossless data compression, which reduces load on networks and saves money when paying per MB of data.
4. Timeouts and Disconnections
Plagued with timeouts? Need recovery faster than the unconfigurable 6 minute timeout that comes with DCOM? MatrikonOPC 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 Tunneller now features data stream encryption. "Man in the middle" type of attacks can now be thwarted, because the OPC data is not readable without the key. Encryption can be selected from 64, 96, or 128 bit AES. OPC 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 Tunneller reduces your integration time to minutes!
- Install Matrikon OPC Tunneller on both the OPC Client and OPC Server nodes
- On the client node, define an IP address or computer name to connect to.
