Focus on Ethernet Routers/Switches
Industrial Ethernet switches
The series 9721 unmanaged switches have ATEX and IEC Ex certifications. The networking product is suitable for process plants with fast Ethernet infrastructure in hazardous areas. The series 9721 switches have four FX ports for optical fiber cables with the “op is” (inherently safe optical radiation) type of protection, according to IEC EN 60079-28:2015, which is akin to electrical type “i” intrinsic safety. Connected lines can be plugged in and out even in explosive atmospheres in zone 1 and 2 (hot plugging). With a shutdown no longer required, changes or extensions to an installation become more cost effective. Optical fiber cables can be used for fast data communication, especially in plants with distributed systems where considerable distances must be bridged or where strong interference may be an issue. The switches themselves can be operated in zone 2, while their 100 Mbit/s optical ports connect field devices, such as the Ethernet-enabled IS1+ remote I/O system in zone 1.
Scalance XC-200 switches
With the Scalance XC-200 product line, users can set up electrical and optical line, star and ring structures in industrial networks. The layer-2 network components can be integrated into both Profinet and EtherNet/IP diagnostics. The switches have many ports and connections, a temperature range of –40°C to +70°C, and approval for hazardous areas (ATEX Zone 2, IEC Ex). As a result, they can be used in mechanical engineering, transportation, the automotive industry, and the oil and gas industry. For transferring large volumes of data, workers can use the Scalance XC206-2SFP switch with two gigabit ports to transmit video data, for example, from tunnel cameras to a control center.
The XC-200 devices are available in different versions, with up to 24 RJ45 ports and two ST/BFOC or two SC ports. With the XC206-2SFP, users can select two ports. Depending on what is needed, fiber-optic SFPs are used for single mode with a maximum range of 200 km or for multimode with a range of up to 5 km. All of the devices are equipped with a redundant power supply. The housing and the collars and the connectors and cables ensure RJ45 connections in environments where equipment has to endure shock and vibration. Users can mount the switches on the wall, on a 35-mm DIN rail, or on a Simatic S7-1500 mounting rail. Clearly arranged diagnostic light-emitting diodes and a signaling contact enable precise determination of the state of the equipment and diagnostic evaluations.
PoE Ethernet switches
The N-Tron series of industrial power-over-Ethernet plus (PoE+) gigabit products now include NT24k-16TX-POE, 1008TX-POE+, and 1000-POE4+. The switches are compliant with IEEE 802.3af/at. The PoE products have metal DIN-rail mountable enclosures and plug-and-play installation. They also include a built-in power boost circuit that allows 24 VDC power input to meet PoE voltage requirements.
The NT24k-16TX-POE’s layer-2–managed gigabit switch has 16 10/100/1000BaseT(X) RJ45 ports. PoE management allows quick allocation of the switch’s 240-watt PoE power budget to any of its 16 ports (up to 30 watts per port). It also has auto IGMP configuration, N-Link and N-Ring technology, RSTP, N-View monitoring, CIP messaging, SNTP, IEEE802.1x, and radius remote server authentication.
The 1008TX-POE+ is an industrial unmanaged gigabit switch that provides eight 10/100/1000BaseT(X) RJ45 ports, including four PoE+ capable ports (up to 30 watts each), jumbo frame support, and light-emitting diode link/activity and PoE status indication.
The 1000-POE4+ is an eight-port gigabit mid-span PoE+ injector with four 10/100/1000BaseT(X) RJ45 ports (data in) and four 10/100/1000BaseT(X) RJ45 PoE+ ports (data and power out) that support 30 watts per port.
The rack-mount managed Ethernet switch is a layer-3 full gigabit managed switch with 24 100/1000Base-TX ports, eight 100/1000 RJ45/SFP combo ports, and four gigabit SFP ports. With an aluminum fin case without cooling holes, it can be deployed in substations. The JetNet 6828Gf has wire-speed switching, where the full gigabit traffic can be transmitted without packet loss and collision. The eight combination ports allow users to trunk up to 8G uplink bandwidth and allow up to 12 fiber capability. With full gigabit capability, the product can perform as a core switch in the substations for high-bandwidth data transmission.
The switch supports Virtual Router Redundancy Protocol (VRRP) and Open Shortest Path First (OSPF). VRRP provides automatic assignment. When a master router fails to connect, the backup router is automatically switched to the new master router. OSPF is often used in large network-like substations; it can calculate the shortest route for data transmission and make the process more efficient.
The essential valve system series is a modular valve system. ES05 orders are supplied as complete assembly kits. All components are unique, and all fittings are of the same type and tightened with the same torque. The portfolio also includes the essential test box, which can be used to test the correct function and leak-tightness of valves before installing the valve system.
The valves come in a housing made of high-performance polymers. Users connect the end and base plates and can extend the system in pairs up to 12 single or double solenoid valves. The valves are controlled via single wiring with a type CI plug according to ISO 15217, a D-Sub connection with 25 pins, with AES valve electronics, or with an integrated IO-Link interface. AES supports all common fieldbus and Ethernet protocols. If necessary, the pilot coils can also be turned at a later stage for mixed connection configurations. With a switching time of less than 35 milliseconds for all valve functions, dynamic action is guaranteed for short cycles. With single wiring, the ES05 complies with protection class IP65, so the valve system can also be installed in decentral locations, even in environments exposed to splash water. All other connection types comply with protection class IP50.
Direct mass flowmeter
The ST100 air/gas thermal flowmeter has a fast-response direct mass flow sensor for the close ratio control of natural gas and air feeds to support turbine safety and improve efficiency. Combined cycle power plants operate with both natural gas and steam turbines to produce up to 50 percent more electricity from the same fuel as traditional fossil-fuel power plants. The steam turbine is driven by the waste exhaust gases from the natural gas turbine. The ST100 thermal flowmeter allows the operator to achieve a direct ratio of control between the natural gas, the air, and waste gas fuels without any corrections for pressure, temperature, or density.
The thermal flowmeters measure the mass flow rates of both natural gas and air in line sizes from 1-inch gas pipes to air inlet ducts that are 2000 by 2000 mm. The ST100 can be applied not only on cold fresh air intakes, but also at preheated or combustion air feeds to the gas turbines. Their SIL rating is based on certified failure mode effects and diagnostic analysis reports.
The device's standard turndown is 100:1, with an optional 1000:1 turndown available. The in-line style configuration is for line sizes from 0.75 to 2 inches, and it measures flow rates from 0.01 to 3000 kg/hr. The insertion style is for line sizes from 3 inches to 6000 mm, and it measures flow rates from 1 to 1.000.000 kg/hr depending on line size. The ST100 flowmeter is compatible with operating temperatures from -40°F to 850°F (-40°C to +454°C).
