Building Highly-Available Automated Systems with Redundancy

Posted by Ray Labbe

Redundancy is something that every company strives for in their automated process, but is one of the hardest functionalities to implement successfully. Companies across the globe are working with solutions comprised of disparate devices, HMI/SCADA systems, historians, and MES systems—each of which has various support for integrating a redundant solution. As an Applications Engineer at Kepware, I have the privilege of answering the question, “How can we implement a redundant automated solution?”

I’m happy to say that by leveraging Kepware’s portfolio of products, redundancy is possible even for customers with unique environments. One of the tools we provide is Media Level Redundancy, an advanced option for KEPServerEX that is supported in Master drivers and drivers that do not require third-party interface cards or library files. Accessed in KEPServerEX through the driver's Device Properties | Redundancy tab, Media Level Redundancy (MLR) was enhanced in the June 2015 release of KEPServerEX version 5.18.

Reimagining Your Remote Communications with a New Distributed Architecture

Posted by Steve Sponseller

Optimizing communications between devices in the field and the centralized applications that need their data is a critical component to the success of a SCADA implementation. The networks that support these communications typically use radios, cellular networks, satellite links, or other types of wireless technology. Due to the bandwidth limitations of these networks, a non-streamlined and inefficient communications solution compromises the network’s ability to acquire and manage data as needed. This blog will discuss a new approach to a communications architecture that simplifies, enhances, and increases the reliability of data collection in a SCADA environment. 


Mobile Technologies: Driving Next Generation Communication Systems

Posted by Erik Dellinger

Mobile technologies are driving the next generation of centralized monitoring and communication systems, especially in the Agricultural industry and in other industries whose remote locations span vast acreage. Instead of physically visiting a remote site and wasting precious response time, engineers can respond instantly to alerts, alarms, or isolated changes in system performance with a few taps on their Smartphone, iPad, tablet PC, or computer connected to the Internet.


OPC Tunneling with OPC Unified Architecture (OPC UA)

Posted by Erik Dellinger

For most businesses, data consolidation, sharing, and visibility across the enterprise is a top priority. OPC Classic enabled many organizations to achieve these objectives. However, there have been several obstacles caused by limitations in the Microsoft Component Object Model (COM) and Distributed Component Object Model (DCOM). Despite being widely adopted, these two options are limited in the usability and security options required by today’s industrial automation and distributed operation environments.
