Similar to the XYR 6000 wireless transmitter,the SmartLine Wireless product line is part of theHoneywell OneWireless™ system and is ISA100 -ready.The SmartLine Wireless Temperature transmitterenables customers to obtain data and createinformation from remote and hazardous measurement locations without the need to run wires, where running wire is cost prohibitive and/or the measurement is in a hazardous location. Without wires, transmitters can be installed and operational in minutes, quickly providing information back to your system.The previous generation transmitters primarily were applied to monitoring applications but experienced users know that Honeywell’s wireless products are as reliable, secure, and safe as their wired counterparts. With this knowledge, users are now looking for wireless transmitters for use in specific control applications.Figure 1 — SmartLine Wireless Temperature DITransmitterSmartLine Wireless introduces a step change in performance and most notably, performance suitable for control. SmartLine Wireless performance is improved in these ways:•Fast ½ second publication rate.•Higher radio range coverage.•More powerful 4dBi integral antenna.•Smarter local display with more localdiagnostics and radio signal and qualityindicators.•More input channels and types than earlier.XYR 6000 Wireless Pressure Transmitter Differential Pressure Models 2SmartLine Wireless Temperature retains the following desirable features from the XYR 6000 product offering:•Mesh or non-mesh configuration within each transmitter.•Generic, off-the-shelf lithium ion battery.•Two “D” size batterie s for longer life.•Choice of over-the-air or local provisioning (network security join key).•Over-the-air firmware upgrade capability.•Unique, encrypted provisionng key delivered from the factory.•Remote and integral antenna options.•24 VDC power option.•Publication rates of 1, 5, 10, or 30 seconds, plus new selections of ½ seconds and 1, 15,30, 60 minutes.•Transmitter range (integral antenna) of 1150’ (350 m) under ideal conditions.The STIW400 is a high-performance Temperature transmitter featuring performance over a wide of temperature configurations and applications.The SmartLine family is also fully tested and compliant with Experion® PKS providing the highest level of compatibility assurance and integration capabilities. SmartLine easily meets the most demanding application needs for Temperature measurement applications. SmartLine Wireless FeaturesLocal and over-the-air provisioning capability:All Honeywell wireless devices feature a secure method to join the local wireless network, also known as provisioning. SmartLine Wireless transmitters feature two methods to provision a transmitter onto the network which are eitherby using a handheld device to locally communicate through the IR interface or remotely using the over-the-air function. The over-the-air function is managed by the OneWireless gateway, Wireless Device Manager (WDM). Over-the-air firmware updates:Once joined as a member of your OneWireless network, the WDM can download new transmitter firmware releases to each SmartLine Wireless transmitter over the wireless network. Locating and accessing the transmitter locally is not required thus saving time and keeping your personnel in safe environments.Mesh and non-mesh capability: All SmartLine Wireless transmitters can be configured to operate in either a mesh network or a star (non-mesh) network. The configuration is specific to each wireless transmitter and thus the network can consist of a mixture of meshing and non-meshing devices. Non-meshing is desirable for deterministic communications which is preferred for control. Transmission power setting:To comply with local and regional requirements, SmartLine Wireless transmitters are set at the factory to the maximum transmission power setting allowed for the country of use.Non-proprietary battery:Sourcing lithium thionyl chloride batteries is much simpler since SmartLine Wireless utilizes commercial off-the-shelf batteries. Please see the list of approved battery manufacturers later in this specification. Batteries are housed in an IS-approved battery compartment making battery changes safe and easy. Backward compatibility:SmartLine Wireless transmitters can join existing OneWireless networks and interoperate with existing XYR 6000 wireless transmitters or otherISA100 Wireless compliant transmitters or networks.OneWireless Network FeaturesThe core of the Honeywell wireless solution is the OneWireless Network which consists a gateway, access point(s), and field routers.The Wireless Device Manager (WDM) serves as the gateway function and in this role, manages the communication from the wireless field devices to the process control application. Typically, the WDM connects logically to the process control network (Level 2 or wireless DMZ). As the wireless network manager, the WDM provides easy access to the entire wireless network through a browser-based user interface. The Honeywell WDM can manage devices communicating over theISA100 Wireless protocol and the Wireless HART protocol.The ability to deploy redundant WDMs improves the reliability ensuring no loss of process data which is a requirement for control applications.The Field Device Access Point (FDAP) serves in two roles in the OneWireless network infrastructure, which are: 1) access point, and 2) field router. As an access point, the FDAP directly connects to the WDM via Ethernet LAN cable. More than one access point is permitted and, when more than one is present, it ensures dual path for communications into the WDM from the field devices. As a field router, the FDAP located in the field would communicate to the FDAP acting as an access point. Using the FDAP as a router is more efficient than using field devices as routers since FDAPs are line powered devices whereas field devices are typically battery powered, and the FDAP offers greater range. The meshing capability of FDAPs allows flexibility in the setup of the wireless network to fit the requirements for wireless network performance, in terms of reliable communications, performance, and future growth. The choice of non-meshing network may be desirable for reduced communication latencies with a FDAP serving as a field router.Wireless Specifications*Actual range will vary depending on antennas, cables and site topography.SpecificationsOperating Conditions1 The Ambient Limits shown are for Ordinary Non-Hazardous locations only.

iMax(Worldwide Interoperability for Microwave Access),即全球微波互联接入。

WiMAX的另一个名字是802.16。

WiMAX是一项新兴的宽带无线接入技术，能提供面向互联网的高速连接，数据传输距离最远可达50km。

WiMAX还具有QoS 保障、传输速率高、业务丰富多样等优点。

WiMAX的技术起点较高，采用了代表未来通信技术发展方向的OFDM/OFDMA、AAS、MIMO等先进技术，随着技术标准的发展，WiMAX逐步实现宽带业务的移动化，而3G 则实现移动业务的宽带化，两种网络的融合程度会越来越高。

因在数据通信领域的高覆盖范围(可以覆盖25～30英里的范围),以及对3G可能构成的威胁，使WiMAX在最近一段时间备受业界关注。

该技术以IEEE 802.16的系列宽频无线标准为基础。

一如当年对提升802.11使用率有功的Wi-Fi 联盟，WiMAX 也成立了论坛，将提高大众对宽频潜力的认识，并力促供应商解决设备兼容问题，借此加速WiMAX 技术的使用率，让WiMAX 技术成为业界使用IEEE 802.16 系列宽频无线设备的标准。

虽然WiMAX 无法另辟新的市场﹙目前市面已有多种宽频无在线网方式﹚，但是有助于统一技术的规范，有了标准化的规范，就可以以量制价，降低成本，提高市场增长率。

短期而言﹙2004年﹚，WiMAX 论坛将在年底之前，着手开发认证流程，为最后一步的产品测试预作准备。

With a compact design for assigned motor ratings from 0.25 kW to 5.5 kW, M-MAX can offer maximum flexibility. M-MAX also demonstrates how a high level of functionality can be implemented in a simple and user-friendly design. The small and compact book format design also allows a space saving installation. M-MAX is provided with an integrated RFI filter (EMC) and a flexible interface for solving important machine building requirements, for example, the optimization of production and manufacturing processes. It reliably ensures the required motion sequences of the drive motor and thus contributes to operational safety.M-MAX – the “energy optimizer“M-MAX frequency inverters provide an economical solution for several processes in pumping applications. The integrated PI controller and extensive motor-protective functions ensure a high level of operational reliability and allow significant energy savings in the connected process. The lacquered control boards also allow use in highly humid and aggres-sive environments, such as in a sewage treatment plant. The optional MMX-IP21-FS... accessory enables the degree of protection of the M-MAX to be increased to IP21.M-MAX – the “safe operator“Good climatic conditions as well as safe operation in the event of fire (fume removal) are demanding tasks for frequency controlled ventilation systems in buildings. With its internal protective circuits and the automatic restart option (e.g. after a momentary power failure), as well as automatics ynchronization with the running motor (flying restart circuit), the frequency inverters of the M-MAX series ensure the safe operation of fans in air conditioning and smoke control systems.M-MAX – for “dynamic precision“The compact design of the M-MAX saves valuable mounting space in machine building since the RFI filter and the brake chopper are already integrated. Shielded control and motor cable can also be connected with EMC compliance directly to the frequency inverter. The maximum permissible ambient temperature of +50 °C during operation with continuouscurrent and with full overload withstand capability also meets machine building requirements. The performance of the sensorless vector control ensures also a high speed accuracy; even with load deviations and low motor speeds.MMX-COM-PC – the “in-line communicator“The MMX-COM-PC communication module that can be plugged onto the front provides the following without a mains voltage on the frequency inverter (internal battery):Upload and download of all parameters,• Direct link to a PC via USB interface (parameter • assignment),Copying of parameters for series machines or when • exchanging devices.This communication module considerably increases datas ecurity and reduces the time required for commissioning and maintenance.FeaturesIntegrated RFI filter (EMC: C2 and C3 to/EN61800-3)• Dynamic motor control with sensorless vector control or V/f • control (selectable)Integrated keypad and display unit• Electronic reference value potentiometer • Fixed frequencies • PI controller• Integrated brake unit (with MMX34 in sizes 2 and 3)• 6 digital control inputs (24 V DC)• 1 digital output (transistor, 24 V DC, 50 mA)• 2 analog inputs (0...+10 V DC and 0/4.20 mA)• 1 output analog (0/4...20 mA)• Serial interface (RS485 / Modbus RTU)• 2 relays (1x NO, 1x changeover, 230 V AC, 2 A)• International standards (CE, UL, cUL, c-Tick)• Application examplesSpeed control of asynchronous three-phase motors up to • 5.5 kW (400 V)Pump and fan applications in buildings and industrial areas • with quadratic and linear load characteristics.The high speed accuracy (sensorless) allows a whole range • of possible applications in the textile, paper and printing industry, as well as with finishing machines in the metal industry.The compact design with integrated EMC filter offers• maximum flexibility in machine building and saves valuable mounting space.The twofold startup torque and 1.5 overload torque allows • the implementation of applications with demanding speed and torque requirements.Frequency inverters - simple and straightforwardDisplay unitFunction keysSTARTMotor start via keypad(function must be activated)STOPMotor stop via keypad• Acknowledges the display fault message (Reset)• Activates the Startup Wizard (press for 5 s)• OKActivates the selected parameter • Confirm the set value• Parameter group selection (submenu)• BACK/RESETBack in menu.
