Cisco and Rockwell Automation helps simplify IP Address Management

When building a machine, skid or industrial application, engineers often re-use IP addresses. Network address translation (NAT) is a methodology that enables this without introducing a duplicate IP address error into the plantwide architecture. A new white paper from Cisco and Rockwell Automation, “Deploying Network Address Translation within a Converged Plantwide Ethernet Architecture,” provides guidance and validated architecture designs to help engineers deploy NAT for one machine or skid, or for an entire cell or area zone in a plant.

Manufacturers benefit from NAT when the IP address space within the plantwide network infrastructure is limited and not every device needs to communicate outside the skid or machine-level network. Meanwhile, OEMs can leverage NAT to more quickly replicate skids and machines.

The white paper summarizes key design principles from a comprehensive design and implementation guide on NAT.

Deploying Integrated and Scalable Ethernet Redundancy with PRP/HSR

Moxa Ethernet Strategies.jpgIn this paper, Moxa examine existing substation topologies and possible integral and scalable methods to achieve efficient redundancy with PRP (parallel redundancy protocol) and HSR (high-availability seamless redundancy). An optimized IEC 61850 PRP/HSR architecture should provide scalable integration for easy modification of functionalities and extension of the substation. Upgrading SANs (single attached nodes) and DANs (dual attached nodes) to a PRP/HSR network will require an efficient and cost effective solution in order to construct a seamless/bumpless communication infrastructure to ensure maximum system availability.

Some of the first power substations in the 1920’s were simple adaptations of devices used for monitoring and control of electrical systems. In today’s complex substation automation  industry, network and system reliability is paramount in ensuring onsite safety and consumer quality of service. One solution to ensure highly - reliable system communication is to implement network redundancy without the impact from a single point of failure. In this article, we will examine existing substation topologies and possible integral and scalable methods to achieve efficient redundancy with PRP (parallel redundancy protocol) and HSR (high - availability seamless redundancy).

With IEC 61850-compliant devices specifically calibrated for PRP and HSR redundancy, seamless control and monitoring can be achieved by using a cost-effective hybrid network topology.

Cable basics: Shielded vs. unshielded cable

cable-jackets1.jpgOne of the most obvious advantages copper offers is that it is less expensive than fiber cable and much easier to terminate in the field. The type of cable you choose depends on the environment and application.

Twisted pair cable used in networking applications typically consists of four pairs of 22–28 AWG copper wires, each covered by insulators and twisted together. There are two types of twisted pair cable, unshielded and shielded.

Shielded vs. unshielded cable:

Unshielded twisted pair:

This is the most widely used cable. Known as balanced twisted pair, UTP consists of twisted pairs (usually four) in a PVC or plenum jacket. When installing UTP cable, make sure you use trained technicians. Field terminations, bend radius, pulling tension, and cinching can all loosen pair twists and degrade performance. Also take note of any sources of EMI. Choose UTP for electrically quiet environments.

Shielded twisted pair:

Over the past twenty years, the need for speed in networking has driven new cabling specifications and technologies at an ever-accelerating rate. Alongside the development of each generation of Ethernet are corresponding developments in cabling technologies. Part of that development is the increased use of shielded cable. It’s becoming more common in high-speed networks, especially when it comes to minimizing ANEXT in 10-GbE runs.

Wireless Technologies for Industrial Communication

Industrial Networks.jpgWireless communication in tough, demanding applications is nothing new. Wireless has been used for more than 30 years through the use of proprietary radios. However, with the modernization of industrial networks and the emergence of different Ethernet protocols, there has been an increasing demand for standardized wireless technologies. During the last 10 years, standards like Wireless LAN (IEEE 802.11) and Bluetooth technology (IEEE 802.15.1) have become the dominating wireless technologies. In 2011, Bluetooth low energy technology also entered the scene. This whitepaper compares the wireless technologies available so you can find the solution that fits your application the best.

Multi-Protocol Wireless Communication Based On The Isa100.11a Standard

Yokogawa Wireless protocol.pngOne of the international wireless standards for industrial use, ISA10 0.11a, was first established in 2009. Since then, wireless has been introduced into many industrial areas, and the recognition of industrial wireless technology has continued to grow as application examples increase. Nowadays, the use of wireless is spreading  further, and various types of sensors are beginning to be required. Even for existing systems using wired communications, wireless technology is considered as a communication means to collect information from already installed field devices, for example, diagnostic information concerning the devices.

In order to meet these requirements, various types of wireless field devices will need to be provided, and the means to unwire already installed wired field devices required. As a solution to satisfy both requirements, Yokogawa has developed the FN310 field wireless multi-protocol module, an adapter which can unwire existing wired field devices. The FN310 is capable of wireless communications using existing protocols such as Modbus and HART. Therefore, users do not need to waste their existing assets even if the field communication is changed to wireless. To achieve this feature, the FN310 applies the ISA100.11a standard, which enables wireless communications using various field digital communication protocols. The FN310 is used in combination with the FN110 under the concept of “Wireless Anywhere”. The FN110 is explained in “Field Wireless Communication Module toPromote Field Wireless” in this issue. This paper describes the F N310.
