Control Automation

I hate boring technical articles. So today, we’ll mix a Modbus tutorial article with some basic protocol theory and learn why it’s really important to understand client/server relationships when critical equipment is on the line. Figure 1. Modbus: who wins? And who loses?

Hello, I work at a power plant. A few days ago, our turbine tripped and shut down. After the turbine stopped, I noticed that the Atomizing Air Booster Motor was still running. I expected the motor to stop when the turbine was shut down, so I would like to understand the logic behind this operation. Is it normal for the Atomizing Air Booster Motor to continue running after a turbine trip? What signal or control logic keeps it running?

Hello everyone, Our gas turbine control system on site uses the GE Mark V HMI. It seems that our CARD_ID.EXE is not working properly. When I click the CARD_ID.EXE icon, a window briefly appears and then disappears almost immediately—so quickly that I cannot even see what is displayed in the window. This is my first time using CARD_ID.EXE, so I’m not sure whether the program can be launched simply by double-clicking the program icon, or if there is another way to start it. Thank you for your help.

JMW, I am writing to address a few of your concerns/observations as 1) they are indeed valid and 2) there have been a few responses via Sciam [salesmen] that haven't directly addressed your points raised. When debuting the DM3 technology, we were very cautious to unveil all of the inner workings as it is such a simple method and we were a relatively unknown company. During each initial conversation with suppliers, re-sellers, and competitors a buy out conversation was offered without fail.

What is expected usable life of any 24VDC power supply if continuously being in use in DCS & PLC System ? Since product datasheets of renowned make power supplies define MTBF more than 3,50,000 to 5,00,000 hrs, but that is not the practical case. Any documented evidence will be helpful.

Emerson is expanding its Ovation process automation portfolio with AI-powered tools designed to help operators and maintenance teams identify problems faster and keep critical systems running. The upcoming Ovation 4.0 release adds specialized AI agents for sequence troubleshooting, alarm analysis, root cause identification, predictive maintenance, and control-loop monitoring.

New Controls Engineer Opportunity – Florida, USA A growing industrial automation company is looking for a Controls Engineer to design, program and commission advanced control systems for ozone generation and water treatment applications. This is a great opportunity for engineers who enjoy taking ownership of complete automation projects—from design through commissioning.

Hi. I was the project manager for the above system which was produced at Lucas' Research Centre in Shirley, B'ham in 1987. Before shipment to the Cannock Headlamp Factory, a promotional video was made, that I used as part of my presentation to the British Robotics Association again in 1987. Does anyone know whether a copy of this video still exists? I would love to get hold of a copy for my personal files, if there is a copy out there.. 124.5 KB

Siemens is adding artificial intelligence and modern software development practices to industrial engineering with updates to its automation and simulation portfolios. SIMATIC AX WinCC Unified Elements brings Git integration, code-based workflows, and AI-assisted visualization development to HMI engineering, while expanded Simcenter capabilities use AI to accelerate simulation and explore new designs.

Innovative companies including ABB, Rockwell Automation, Inc. (RA), Augury, RiACT, and DOBOT Robotics (DR) are making strategic partnerships and other business agreements to provide software and hardware technologies that enhance machine health monitoring and maintenance, promote robotics and automation adoption, expand automation offerings for customers, enhance operational efficiencies, and improve sustainability.
