Matrikon OPC Tunneller™ Software
Eliminate DCOM setup headaches. Matrikon OPC Tunneller™ software gets your networked data
moving without pain. It doesn't get any easier!
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
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
- Related diagnostic information
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
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.

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
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
On the client node, define an IP address or computer name to connect to.
