OPC Tunneller™ software from MatrikonOPC (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.

While DCOM requires a reliable communication network, OPC Tunneller™ software operates under poor initial network setup, widespread networks, and unreliable network infrastructures such as satellite or wireless networks. OPC Tunneller™ software even allows for user configurable time-outs, thus giving you complete control.

Features and Benefits:

  • Easy configuration.
  • Seamless OPC data transfer through multiple mediums across geographical locations.
  • Reliably transfer real-time, historical, and alarms field data to a centralized historian.
  • Data encryption for security.
  • High performance data compression to utilize less bandwidth.
  • Communication with multiple OPC servers and clients simultaneously.
  • Alarm and Events specific:
    • Simple, Tracking, and Conditional Events are supported.
    • Subscribe and Receive Conditional Alarms and Events.
    • Automatic refresh method to update the state of condition events.
  • Added 64 bit support for both Client Side and Server Side connections.
  • Status tags provided for OPC real-time data items monitoring
    • Connection status
    • Licensing

The Encryption feature in Matrikon OPC Tunneller™ software 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 Tunneller™ software 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 Tunneller™ software 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™ software. 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™ software 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 Tunneller™ software 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 Tunneller™ software 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™ software 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 Tunneller™ software 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™ software reduces your integration time to minutes!
  • Install Matrikon OPC Tunneller™ software 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!
