How to Connect, Integrate, or Communicate between Control Systems

Our Automation 101 blog series is designed to help professionals that are new to the industrial automation space whether at the start of their careers, or moving into the operations technology (OT) world from an IT or other background.

One of the common challenges in Industrial Integration is communications between different brands or manufacturers’ control devices (PLC, DCS, Drives, RTUs, smart sensors).  While most control devices have methods of communication, and some industry standards have helped, they don’t all communicate using the same methods or protocols, and even if they both have the same serial or Ethernet wiring the difference in communication protocols prevents them from passing information.  It’s the same problem you have if someone calls you on the phone, but doesn’t speak the same language.

While, as humans, we may be able to overcome a difference in dialect, machine communication has to be precise and exact.  Small differences in addressing or data formatting can be enough variation to create communications failure. So how do people overcome this challenge?

Bridging the Gap between OPC, DDE, ODBC and Other Data Sources

Posted by Win Worrall on Sep 7, 2017 2:00:00 PM

Do you need to directly connect data points or variables in different equipment, processes, or software? This concept is commonly referred to as ‘point-to-point bridging,’ and the DataHub bridging capability allows multiple data sources to communicate with each other in real time.

In this second post of our “I Can Do That?” blog series, we’ll help users like you get the most out of your DataHub by understanding the bridging feature in detail and how this feature can often be combined with other features to accomplish some very powerful automation tasks.
