The basis of good flowmeter selection is a clear understanding of the requirements of the particular application. Therefore, time should be invested in fully evaluating the nature of the process fluid and of the overall installation. The development of specifications that state the application requirements should be a systematic, step-by-step process.
In this Essentials guide, the editors of Control walk through the alternatives, explain how to narrow your choices and uncover the latest application trends.
FDT Technology is an international standard developed to standardize the communication and configuration interface between smart field devices and their host systems. The enhancements and development from FDT to FDT2 were driven by changing technology and user requirements. The challenges were to maintain all existing features and benefits, add new capabilities based on real-world applications and enhance areas of identified improvements, all this done against a backdrop of maintaining backward compatibility. The following overview of the enhancements included in FDT2 identifies how the specification has addressed the needs of users and suppliers.
Many industrial networks are based on the EIA-485 or RS-485 communication standard. As industrial systems and products rapidly move to IP-based Ethernet networks, RS-485 network operators face complex and expensive obstacles in the transition from RS-485 serial communication to Ethernet communication infrastructure. In this white paper, PCN introduces IP-485, an open standard approach to modernization of RS-485-based industrial automation and distributed control infrastructure, allowing instant connectivity to the Cloud, without impacting security and reliability. With IP-485, users can keep their RS-485 network and get Ethernet networks on the same cabling already installed!
The ability to securely move information between software applications and hardware appliances is critical to any automated process. To make this possible, an interoperable communications platform must be layered into the control system. This "defense-in-depth" approach ensures that critical information will not be deciphered by non-authorized applications for malicious use. This approach also limits the scope of activities that each authorized user is allowed to do and/or access in the system in order to minimize unintentional mistakes that may cause downtime or impact safety. With KEPServerEX V5.12 and the new Security Policies Plug-In, Kepware now provides a complete solution to this market need.

Controller tuning can be accomplished quickly and accurately using proven techniques. While many engineers and technicians resort to "tune by feel," most will admit that this approach yields inconsistent results. These best practices help to ensure that controller tuning changes from "part art, part science," to a very consistent scientific approach.
Without measurement there is no control. As with any type of measurement, results need to be expressed in a defined and clear way to allow everyone to interpret and apply those results correctly. Accurate measurements and good measurement practices are essential in industrial automation and process environments, as they have a direct effect on the success of the desired outcome.
Pressure, the measure of a force on a specified area, is a straightforward concept, however, depending on the application, there are many different ways of interpreting the force measurement. This white paper will identify the various units of pressure measurement, while discussing when and why certain pressure measurements are used in specific applications.
Manufacturing firms have used remote management of automation tasks for a number of years and for a variety of reasons. But due to recent changes in technology and strategy, remote management has recently jumped to the forefront.
