OPC DataHub Now Ensures Security of OPC Data Over a Network
The latest version of the OPC DataHub features
built-in SSL encryption to provide secure tunnelling of OPC data
across a network or the Internet.
Georgetown, Ontario (July 31, 2007) The OPC DataHub from Cogent Real-Time Systems
now includes SSL encryption as a standard feature, providing
high security for connecting manufacturing and process data
to the rest of the enterprise. Based on the OPC DataHub's
established ability to link OPC servers and clients across a
network, and to bypass the pitfalls of DCOM, SSL encryption adds
yet another option to ensure safe and reliable data
"Process control environments were once islands unto
themselves," said Andrew Thomas, president of Cogent. "As the
need grows to connect them to each other and to the rest of the
company, the need for security grows as well. This latest
version of the OPC DataHub was specifically designed to meet
In the past, transmitting OPC data over a network relied
on DCOM, which was not designed for securing real-time data
communications. Since industrial networks were completely cut
off from the Internet and even corporate networks, security was
not an issue. But now, easy access to process data made
possible by widespread acceptance of OPC has created a need for
rapid, robust, and secure data transmission across a network.
The OPC DataHub replaces DCOM with OPC tunnelling that is
firewall-friendly, easy to configure, low bandwidth, and
recovers quickly from network breaks. OPC DataHub's SSL feature
maintains all of these advantages while adding one-click
configuration for secure SSL transmission.
The OPC DataHub gives quick, reliable, and secure access to
valuable information direct from the factory floor. It is an
integrated tool that can present live process data directly on
an engineer's or manager's desk in a form most suitable:
database, spreadsheet, or web page. This new SSL encryption
ensures a high level of security for critical plant data being
transmitted across a network.
