Wireless technologies have been used for decades in the water/waste water industry in a multitude of applications including tank level indication, pump and motor control, flow and pressure monitoring, etc. However, recent concerns regarding the potential for hacking and cyber-attacks into these wireless systems have raised the importance of wireless security to a new high. This paper will discuss security issues within an Industrial Wireless Network, and address the ways in which these networks can be designed to be more reliable while being more secure.
As manufacturers with batch operations strive to improve shareholder value through increased profitability, they are increasing investments in factory automation to reduce costs and increase operational flexibility. Equipment suppliers have responded with more capable devices, controls and software to meet these needs.
A new concept for an Electronic Flow Control Valve (EFCV) with pressure compensation capability is introduced. Based on its embedded sensors and micro controller, the EFCV can provide flow control without the need of load/displacement/speed information from the power elements, like hydraulic cylinders or hydraulic motors.
Ethernet just celebrated its 30th birthday. In 1983, IEEE published the 802.3 standard as a draft and, ever since, Ethernet has come to dominate the commercial and consumer world. Every home PC comes with an Ethernet port, and virtually all communications are done via Ethernet—except in the industrial world.
For decades, process instrumentation specifiers have faced the decision whether to use a mechanical switch or a continuous transmitter for a given application. Either type of instrument can be used to effectively control industrial processes and protect equipment and personnel -- and each has associated pros and cons. Application specifics typically drive decision-making, dictating which approach is most effective from performance, cost and lifecycle support perspectives.
This article discusses calibration in hazardous areas and what everyone needs to be aware of before entering into a hazardous area with calibration equipment. Other topics covered are the background of flammable and combustible liquids, definition of a hazardous area, the types of relevant industries, the different levels of zones, regulations, equipment classification and various other related practical issues.
Increase Efficiency, Reduce Costs & Improve Quality. Read this white paper to learn how maximizing the effectiveness and efficiency of factory lighting can enhance operations and make all work tasks easier.
The data historian has long been seen as a venerable workhorse for engineers and technicians in the process industries, but changing economic conditions are forcing managers and executives to realize not only its importance but that it is a critical component to any process industry operation.
Process engineering has undergone significant transformation over the years, catalyzed by advances and innovation in software both within individual disciplines and also in the integration across the workflow.
Applications that require high availability, advanced data handling and superior communication capability are a good fit for PAC redundancy. This white paper looks at the benefits of redundancy, options, and implementation details.
This year's ABB Automation & Power World, held March 25-28 in Orlando, Fla., included a broad range of need-to-know presentations for automation and power professionals on topics ranging from cybersecurity concerns to efficiency and reliability, and data power usage.
The security of industrial automation and control systems becomes increasingly critical as different networks are connected and systems are integrated in a collaborative manufacturing environment. For industrial automation and control systems the potential impact of an attack maybe more serious than for computer systems in general. Users of industrial automation and control systems need to pay correspondingly increased attention to these issues.
