However, over the next five years we predict a steady growth rate of 7.9%, with 2025 expected to be a strong rebound year and offering the biggest annual growth (10.2%). This is expected to drive growth in the global precision gearbox and geared motors, which is forecast to increase from $3.3 billion in 2023 to $4.8 billion in 2028, with a compound annual growth rate (CAGR)of 7.9%.The largest growth overall is attributed to planetary precision gearboxes and geared motors, where we anticipate a CAGR of 10.2%, taking revenue from $1 billion in 2023 to nearly $1.8 billion in 2028.

Control communications can impact performance, quality and reliability. In addition, control devices or the controller play an important role in information gathering to support layered analytics. Selecting an industrial network is pivotal to creating the most competitive machine, production line or process. Ethernet with time-sensitive networking (TSN) is an advanced networking technology that enhances standard Ethernet with features required for deterministic communication and precise time synchronization in industrial and automation applications. TSN is an IEEE 802.1 standard that adds mechanisms to Ethernet to enable deterministic real-time communication with bounded latency, low packet delay variation and extremely low data loss. This makes it suitable for applications with stringent timing requirements, such as industrial automation, automotive, aerospace and professional audio/video.

Three open-loop tuning tips Ed Bullerdiek, retired process control engineer offers PID tuning-with three open-loop tuning tips and two limitations. Three open-loop tuning tips are: 1. Make multiple steps when performing the open loop test (minimum of three). 2. The step sizes should be different. 3. The step sizes should be made in opposite directions. This is necessary to see if the valve is working. (A cascade master may not require multiple steps as valve performance should not be a problem.).

The National Institute of Standards and Technology defines OT as "programmable systems or devices that interact with the physical environment," which is comprehensive of most electronic devices deployed in industry today. We cannot avoid the headlines of the next water treatment facility, pipeline, food processing plant or industrial manufacturer that has suffered yet another ransomware attack. Cybersecurity is one of the biggest gaps in existing infrastructure and are often included in many recent design projects.

From readouts on temperature furnaces and warehouse movements to smart meters tracking energy usage, industries have more data about a greater number of operational processes than ever. Half of all industrial data has been created in the last two years. Estimates show that another 38% of new operational data will be stored and processed in the cloud in 2024. Global technology spending is expected to hit $5 trillion this year. How we collate, analyze and collectively leverage this wealth of data will shape future industrial value. A more connected world can support responsible use of the worlds resources during an era of unprecedented disruption.

What they discovered was staggering: The system was inundated with hundreds of alarms. Some were being triggered more than 50 times a day while others remained in a constant state of alarm for weeks at a time. Further inquiry revealed this scenario was considered normal within the day-to-day operations of the plant. The plant staff were comfortable with the state of their system and the volume of alerts.

With the help of system integrator Flexware Innovation, California American Water - Monterey was able to replace its legacy SCADA system with an industrial automation platform.
查看更多>>摘要：There are three common methods used to tune control loops, open loop, closed loop, heuristics. There is considerable published literature on open- and closed-loop tuning methods, and all control textbooks cover open- and closed-loop tuning. Heuristics methods are not well covered. Each has its place in your toolbox, and there are concepts unique to each method that will help you think critically about control-loop performance. Open-loop tuning is generally the best choice when you have a "cheerfully start over" situation, either a new control loop or one where the process has been significantly modified. Existing control loops that just need to be trimmed up are best approached using heuristics. Closed-loop tuning should be avoided, however, if you happen to walk up to a loop that is already swinging, you have all the information you need to use closed-loop tuning rules.

Assessing drives only for their ability to perform this task overlooks many other powerful ways drives can impact production. Industrial producers want to get more from their control and automation technologies as they face the challenges of a changing workforce, pressures to be more profitable and expectations to reduce environmental impacts. Modern VFDs hold a lot of potential to help producers address these needs by providing access to useful data, seamless yet simplified connectivity and more design options. Whether an engineering team is considering automation options for a new project or trying to get more from their existing equipment, they should look beyond basic motor-control functions to consider how drives can enable achievement of some of their top priorities in production today.
