HART protocol instrumentation is by far the most used of this type of system. The HART Maintenance Device would be just such a tool, providing basic communications and diagnostic capabilities to support the maintenance and troubleshooting of HART instruments.05/14/2012
The last 10 years have seen a major expansion of the use of wireless data technology in every aspect of life and in every industrial venue. From the ubiquitous cell phone to smart phones, tablets and more, wireless data communications have become an important, perhaps the most important, medium. In the last half dozen years, wireless field devices have begun penetrating the industrial environment too. IT and plant floor communications managers are faced with a daunting task in coordinating all the uses of wireless in the average 21st-century plant.
As more and more wireless devices and applications become an integral part of the industrial arena landscape, concern grows over in which layer of the network these wireless devices should be placed. This question concerns everyone since this is sure to impact plant or plant operation in the near future.
We typically see two physical networks. The Process Control Network (PCN) involves Layers 2 and below. The Business Network (BN) involves Layer 4 of the Purdue model. If you are part of a plant team that supports either of these networks, the discussions within this paper have been or will be part of an ongoing discussion for your organization.
We've seen a number of major companies make an attempt to stake out where wireless devices will fall and under what level of the network. This paper addresses these types of issues and is intended to provide answers to the many questions that are sure to arise.04/23/2012

While a molded cable assembly can offer significant advantages over a similar product of a mechanical construction, the art of insert molding remains somewhat of a mystery to cable assembly consumers. While attracted by the potential for a more aesthetically pleasing product that can be sealed from the environment and rendered 'tamper proof', the complexity of the insert molding manufacturing process is often over looked.
Many cable assembly engineers who are consumers - but not producers - of molded assemblies are familiar to some degree with conventional molding. In this environment, the goal is the maximization of process speed which translates directly to bottom line financial performance. Manufacturing lot sizes are often characterized by long runs, where the same part is produced continuously over a considerable amount of time. The molding machines are usually horizontal in construction, use a closed cavity approach with auto-ejection of the finished parts, and operate at much higher injection pressures and speeds than an insert molding process. Additionally, the often uniform nature of the parts relative to wall thickness, balanced runner systems, and sufficient draft on the molded parts being produced serve to support consistent quality in the face of maximum manufacturing speed. The ability to optimize tool cooling, standardize mounting, and implement automated processes are also major differentiators between the conventional horizontal molding and vertical insert molding approaches. The result, all things equal, is a much higher production rate for finished parts in a conventional molding process.
What then are the challenges of the insert molding process used to manufacture cable assemblies, and, more importantly, how are they met by the manufacturer? At a high level there are four major areas of consideration when discussing the intricacies of insert molding. These include the operator, tooling, equipment, and the process itself. Let's examine each of these in more detail.
Operator: As with any non-automated process, it is the operator who is often the most important component of the success or failure of a manufacturing lot. This is especially true in cable assembly molding. In addition to knowing the basics of machine operation, the operator has several variables to properly monitor and control if he or she are to produce parts that meet the established design and quality guidelines. In light of some of the equipment and component variability discussed earlier, some of these operator focused considerations include...04/05/2011
1 Gigabit Industrial Ethernet Field Network Delivers Determinism and Accommodates 10/100/1000 Mb TCP/IP Field Devices
The continuing drive to improve productivity will encourage more automation networking. The driving factors behind this expected growth include lean working, increased traceability legislation, product lifecycle management production (PLM), and improvements in manufacturing cycle times. This requires connecting the factory floor to the corporate offices where enterprise resource planning (ERP) systems make information available backwards into the supply chain, as well as forward to customers. Simply put, everyone wants to see what's happening. As a result, networks and the information they handle are becoming as important as the industrial control functions they manage.
This white paper describes the open CC-Link IE Field network, an Industrial Ethernet technology, which operates at 1 Gigabit/sec. This data rate is 10 times faster than other Industrial Ethernet technologies in order to provide highly responsive control system communications, while at the same time allowing connection to field devices (RFID readers, vision systems, etc.) that have TCP/IP Ethernet ports communicating at slower 10Mb or 100Mb data rates.03/30/2011

Some engineers think it is science. Others contend it is some type of black magic.
Many have no idea of exactly how the process works.
Regardless of what is known or unknown about the submission and evaluation process, there are few that will disagree with the premise that agency certifications, such as those offered by organizations like Underwriters Laboratories (UL), Canadian Standards Association (CSA), or Intertek, formerly known as Edison Testing Laboratories (ETL), to name only a few, are an important part of any product offering in the wire and cable industry. With todays focus on product safety, there has been an increased need for wire and cable products to carry either a listed or recognized mark signifying they have been independently evaluated and have met the appropriate safety guidelines that have been established based on their intended use.
In an attempt to help bring some clarity to the agency certification process for bulk cable, I have posed a series of related questions to Randy Elliott, C&M Corporations Regulatory Compliance Engineer. Randy has been a practicing engineer in the wire and cable industry for over 20 years. His background in R&D and design engineering has brought him into contact with regulatory agencies and their requirements on a regular basis throughout his career. For the past three years, his focus has been completely on regulatory issues for C&M.

ISA100 is one of three standards competing in industrial wireless sensing. What is distinctive about ISA100? What are the prospects for convergence of standards? What would convergence be worth to the industrial wireless market?
ISA100 is a major standards initiative managed by the International Society of Automation (ISA). In addition to standards development, a new organization, the ISA100 Wireless Compliance Institute (WCI), is charged with delivering compliance certification services for the work of ISA100.
The ISA100 committee establishes standards, recommended practices, technical reports, and related information for implementing wireless systems in the automation and control environment, with an initial focus on the field level. Given the committee's broad scope, they have formed a number of working groups to pursue specific tasks. The primary deliverable from the Committee thus far is the standard ISA-100.11a, "Wireless Systems for Industrial Automation: Process Control and Related Applications". However a quick glance at the list of working groups shows that several other topics will be addressed by future ISA100 deliverables.
In 2006, at about the same time ISA100 was forming, the ISA also created the non-profit Automation Standards Compliance Institute (ASCI). This organization manages certification, conformance, and compliance assessment activities in the ISA's automation domain.
ASCI extends the standards work of ISA by facilitating the effective implementation and independent testing of ISA standards. It creates a vital link between the development of standards and industries' implementation of the standards. The ISA100 Wireless Compliance Institute (WCI) functions as an operational group within ASCI. Operating the ISA100 Wireless Compliance Institute within ASCI allows it to leverage the infrastructure of ASCI, which in addition to WCI, is shared by several ASCI compliance programs.11/22/2010

The purpose of this paper is to explore the particular ways in which operators can tightly integrate wireless instrumentation networks with SCADA and realize.
Integrating wireless instrumentation with SCADA systems can drive operational efficiency and reduce deployment costs.
The use of wireless instruments in pipelines and gas production operations has been gaining momentum over the past few years. Driven by cost cutting measures and the need to gain more operational visibility to meet regulatory requirements, wireless instruments eliminate expensive trenching and cabling while providing access to hard-to-reach areas using self-contained, battery-powered instruments. However, SCADA engineers and operators are facing the challenge of integrating wireless instrumentation networks with other communication infrastructure available in the field. Managing and debugging dispersed wireless networks presents a new level of complexity to field operators that could deter them from adopting wireless instrumentation despite the exceptional savings.
This paper will look into the particular ways in which operators can tightly integrate wireless instrumentation networks with SCADA and realize the full benefits of such an integrated solution.06/29/2010
