  SITRANS AW210 WirelessHART adapter

  The WirelessHART adapter SITRANS AW210 is a communication component which can integrate a wide range of field devices into a WirelessHART network. On the wireless communication side, the adapter supports the WirelessHART standard. HART and 4 to 20 mA field devices are connected on the field device side.

  The WirelessHART adapter SITRANS AW210

  • Supports the WirelessHART standard (HART V 7.1)
  • Features an extremely high degree of security for wireless data transmission.
  • Integrates a 4 to 20 mA field device into a WirelessHART network
  • Integrates up to eight HART field devices (in multidrop mode) into a WirelessHART network
  • Can be powered with the 4 to 20 mA loop or an external power supply
  • Power management can be activated to minimize energy consumption
  • Easy to configure with SIMATIC PDM, AMS, Handheld 475.

  Область применения

  The WirelessHART adapter can be used in a number of different applications:

  • Access to installed basis
    Diagnostic information is obtained from existing wired HART devices thanks to the permanent electrical connection of a WirelessHART adapter and power from the 4 to 20 mA loop. This information is sent to central system-based asset management software such as SITRANS MDS.
  • Status monitoring of the plant
    Wireless devices are mounted at critical points in the plant which are not usually connected to the control room due to difficult access or high wiring costs. Better data flow and diagnostics increase plant reliability, transparency and safety.
  • Process optimization
    Temporary installation of a 4 to 20mA or standard HART device together with a SITRANS AW210 WirelessHART adapter allows easier, flexible monitoring and plant optimization at lower costs. SITRANS AW210 can also be usefully used where there is already an external power supply, or one is needed anyway.
  • Process monitoring
    Measured values, for example from tanks or silos, are transmitted to a higher-level system at regular intervals together with the device status. SITRANS AW210 is particularly easy to use with 4-wire devices, as they have an external power supply.

  Дизайн

  SITRANS AW210 WirelessHART Adapter consists of:

  • An enclosure with a fitted aerial
  • Electronics

  

  SITRANS AW210 Wireless-HART Adapter, assembly

  The enclosure contains the potted electronics and the wireless module. The aerial is fitted at the top in the enclosure.

  On the base of the enclosure is the connector with a ½" NPT female thread. Six cables run from this connector to connect the adapter.

  SITRANS AW210 WirelessHART Adapter, functional diagram

  The measured values and diagnostic information from the connected field devices with HART communication are transmitted to the WirelessHART adapter over wired connections. The adapter transmits this information as wireless signals to the IE/WSN-PA link, the Siemens WirelessHART gateway. The measured values, all parameters and diagnostic information about the plant network can be accessed from this gateway.

  If a field device with a 4 to 20 mA output signal is connected to the adapter, the current will be converted to a digital measured value and transmitted on the basis of a measuring range specified in SITRANS AW210.

  Following configuration and integration into a WirelessHART network, each WirelessHART adapter is able to recognize its neighbors. It notes the strength of the wireless signal, synchronizes itself, receives network information and then establishes connections to its neighbors in the wireless network. A WirelessHART network organizes itself. Manual settings for organization are not required.

  Two-wire and four-wire field devices can be connected to a WirelessHART adapter. Either up to 2 or up to 8 HART field devices can be connected to the adapter, depending on the selected product version. The adapter either has an external voltage supply or is loop-powered. The WirelessHART adapter can therefore also be connected in parallel to an existing installation consisting of a voltage supply and a HART field device.

  Parameter assignment

  SITRANS AW210 is configured via HART. Configuration can be carried out using handheld communicator 475 or, more conveniently, with a HART modem and the SIMATIC PDM configuration software.

  Initial startup of the adapter is usually carried out via SIMATIC PDM and a HART modem or a handheld communicator. During initial startup, the network ID and join key are set in the adapter. These parameters are used to integrate the adapter into an existing WirelessHART network.

  Following integration into the network, the adapter and HART devices connected can be conveniently operated via the WirelessHART network or locally, as detailed above.

  Siemens HART field devices for the adapter

  In principle, all HART devices certified by the HART Communication Foundation (HCF) can be operated with the SITRANS AW210 WirelessHART adapter. See http://www.siemens.com/automation/service&support for FAQ with the latest information on connectivity for Siemens field devices.

  Note:

  Siemens has only approved the Siemens HART field devices listed there for the adapter, and will only provide technical support for these devices.

  Based on HART specifications, it is generally possible to connect devices that are not listed, however with the following restrictions:

  • All warranties and liability will be excluded
  • No technical support
