Key Benefits
-
Update or expand systems without the cost of
replacing or re-engineering existing control systems
-
Create a more open system making it easier to
expand further
-
Better integration of information by linking control systems
to: SQL databases, Web pages, SMS paging, Email, etc
Capabilities
There are many ways to exchange data between control
systems; OPC, DDE, Serial Protocols, File shares, etc. Experience shows
that a successful integration design will often require more than one method.
- OPC (OLE for Process Control)
- OPC is the modern standard for linking systems over
networks. We routinely use OPC to link
systems from different manufacturers.
-
- DDE (Dynamic Data Exchange)
- DDE was widely used to exchange data between
MSWindows applications and continues to be used in many older systems.
-
- Serial Protocols
- We have over 20 years experience developing and
debugging serial communications with a wide range of control & I/O
equipment. Where possible, we prefer to use standard protocols such as Modbus
but, where required, non standard protocols can be supported.
-
- Data Sharing
- Where other options don't exist, file sharing is the
most basic method of exchanging data between applications, but great care is
needed to avoid conflicts and timing errors.

Electricity Authority explains, “Over
the years, a number of different vendors have been used to provide
industrial software solutions for turnkey projects.
As we grew, it became increasingly clear that all the information
being collected from these individual sites needed integrating onto single
screens.”
