DeltaV Blog: Integrating Ethernet-Based Devices in DeltaV Systems

Let’s open the week with a video for DeltaV distributed control system users on ways to integrate devices with Ethernet-based protocols into the DeltaV system. Examples of these devices include motor control centers, variable speed drives, programmable logic controllers (PLCs) and various types of online analyzers. In this 6:17 YouTube video , Emerson’s Rune Reppenhagen demonstrates the DeltaV Virtual I...

Blog: Proof Testing Level Measurement Devices

Safety instrumented systems (SIS) include the sensor(s), final control element(s) and logic solver(s) for each of the safety instrumented functions (SIFs) in the SIS. To verify the SIFs are performing the amount of risk reduction intended for their application, they must be periodically proof tested. PCN Europe magazine interviewed Emerson’s Teddy Tzegazeab on how proof testing has changed for SIFs with liquid...

Blog: Network Architecture Considerations in Ovation Control Systems

Emerson’s Craig McDaniel provided an overview on the Ovation control system network architecture at the 2017 Ovation Users Group conference. He provided a basic overview of Ovation’s network architecture showing standard configurations, connectivity, redundancy, IP addressing schemes, port assignments, network hardware, and connections to third party equipment will be provided in this session. He also discussed...

Blog: Reducing Control System Hardware Footprint

Emerson’s Ben Skal presented on reducing the Ovation distributed control system hardware footprint at the 2017 Ovation Users Group conference. Virtualization technology is at the heart of this hardware footprint reduction and having less workstation and server hardware to maintain. Ben’s presentation focused on: What is virtualization & how it works Appropriate uses of virtual machines (VMs) ...

Blog: Model Predictive Control in Power Generation

Model predictive control in power generation was the subject of a 2017 Ovation Users Group presentation by Emerson’s Ranjit Rao . Rajit opened comparing classical control with model-based control. In classical control, a proportional-derivative-integral loop is used with feedback. There is a setpoint, the actual process variable and the error or difference between the process variable and setpoint. Based on the...

Blog: Simulation for Training and Engineering Applications

At the 2017 Ovation Users Group conference, Emerson’s Bob Kerestes and Sheldon Willis gave an update embedded simulation in the Ovation system. Sheldon opened the presentation describing types of uses for simulators for training and engineering. For training simulators, simulations can range from simple tie-back models to high-fidelity models which simulate the dynamics of the running process. For high-fidelity...

Blog: Generator Excitation 101

Generators turn mechanical energy into electrical energy by moving electrical conductors in a magnetic field. Excitation creates the electromagnetic field to make this mechanical to electrical conversion occur. Emerson’s Rich Dennis provided a basics presentation on excitation control at the 2017 Ovation User Group meeting. Excitation control includes synchronous machine regulation, exciter, synchronous machine...

Blog: Suite of Cybersecurity Technologies and Practices

Emerson’s Adam Boeckmann presented the Power and Water Cybersecurity Suite at the 2017 Ovation Users Group conference. He opened describing the team that formed over the last several years that now supports more than 200 sites in the U.S. alone. He shared the story of the recent Wannacry/WannaCrypt ransomware cyber-attack. In March of 2017, Microsoft released a patch. A month later, the National Security Agency...

Blog: Applying Threat Intelligence for Industrial Control System Defense

There are many paths to pursue in improving cyber defenses for industrial control systems (ICS). At the 2017 Ovation Users Group conference, Emerson’s Tom Kizer presented on applying threat intelligence for system defense. Tom opened by acknowledging that identifying effective threat intelligence is difficult. Threat intelligence is data collected, organized, analyzed and refined about potential or current attacks...
