Webinar recap: High Performance–HMI Done Right

Posted by MAVERICK Leadership Team on December 17, 2014 @ 8:00 am

Webinar recap: High Performance–HMI Done Right We had a great turnout at the High Performance–HMI webinar last week, and we’re glad so many of you could attend. Chad Harper and Lee Swindler were on hand to demonstrate the graphical downfalls of many older human-machine interfaces (HMIs) and discuss the benefits of transitioning to High Performance–HMIs. Thank you to everyone who attended, and especially to those who participated by submitting questions. If you couldn’t make it, you can watch the webinar here or read on for a recap of what you missed: The evolution of HMI The information communicated by the first HMIs wasn’t any different from that of modern-day HMIs, but the way the original HMIs presented it was much simpler.

Assembling a startup team for success

Posted by Ryan Harris on December 16, 2014 @ 11:38 am

Most traditional startup teams are comprised of process engineers, controls engineers, electricians, and mechanists—but don't forget to consider plant personnel, too.

What makes up a great startup team? Many traditional teams are comprised of process engineers, controls engineers, electricians, and mechanists. However, there are additions to the team that should be considered, like plant personal operators, and even shift managers.

For contracted projects, every team needs a plant contact; I am talking about plant personnel directly involved in startup activities. With contracted projects, the execution team is often working remotely, which can be hours or even days away from the plant facility. How do you bridge the gap between execution and implementation? Who is left to support the new systems in the plant? Are they properly trained to maintain the new system? Will th... Continue Reading

Integrating third-party systems with a DCS

Posted by Tony Kolluri on December 10, 2014 @ 12:16 pm

Several considerations need to be made when interfacing a distributed control system (DCS) to a third-party system, including the choice between using SCADA or peer-control solutions.

Figure 1: Interfacing a distributed control system (DCS) to a programmable logic controller (PLC). Courtesy: Maverick Technologies Interfacing a distributed control system (DCS) to a third-party system—let’s say a programmable logic controller (PLC)—is most commonly done via SCADA or peer-control using various communication protocols. While it appears that it’s just a task of getting the data ‘in... Continue Reading

Managing CIP Connections

Posted by John Boyd on December 2, 2014 @ 2:34 pm

Properly managing your control system CIP connections can help avoid confusion and other complications within a process automation project.

Common Industrial Protocol (CIP) is used on industrial automation application networks—such as Ethernet/IP, DeviceNet, and ControlNet—and is supported by ODVA. A CIP connection is a connection between two devices on a CIP-enabled network. This could be between two programmable automation controllers (PACs), between a PAC and a communication module, or between a remote rack communication module and an analog card in its rack (see Figure 1). A CIP connection is a connection between two devices on a CIP-enabled network. Cou... <a class=Continue Reading

Using programming standards to navigate your process

Posted by John Athy on November 26, 2014 @ 9:31 am

A definite set of programming and HMI standards can alleviate the burden of navigating your controls process from start to finish.

Imagine you had to navigate from one corner of London to the opposite corner, using only a map. No problem, but what if each square mile of this map was designed by a separate person using different scales, symbols, and languages. Now the task becomes more daunting. This analogy can also apply to process automation, specifically with regards to programming and human machine interface (HMI) development. Not having a defined set of programming and HMI standards can lead to a piecemeal set of systems in the overall process that can leave programmers, maintenance, and operations personal with the burden of navigating through the controls process from start to finish. The key to alleviate this burden is to have a uniform "map;" this is where programmi... Continue Reading
