SITRANS AW200 WirelessHART Adapter

The SITRANS AW200 WirelessHART adapter is a battery-powered communication component, which integrates HART and 4 ... 20 mA field devices into a WirelessHART network. On the wireless communication side, the adapter supports the WirelessHART standard. HART and 4 ... 20 mA field devices are connected on the field device side.

The SITRANS AW200 WirelessHART adapter

  • support the WirelessHART standard (HART V 7.1)
  • features a very high degree of security for wireless data transmission
  • integrates one 4 ... 20 mA field device or up to four HART field devices (in multidrop mode) into a WirelessHART network
  • features intelligent energy management for the power supply of connected field devices
  • can be easily parameterized using SIMATIC PDM
Особенности
  • High quality and service life
  • Save on wiring costs for difficult installation conditions (e.g. moveable equipment parts) or for temporary installations
  • Subsequent integration of an installed field device with HART interface into maintenance and diagnostic systems if the control system does not feature the required communication mechanisms. This application is described in Section 9 of this catalogue under "WirelessHART - Technical Description".
  • Proven HART devices can continue to be used for wireless communication, without any limitations .
  • Field devices with a 4 ... 20 mA interface (without HART) can also be connected.
  • Intelligent energy management to achieve the best possible life time for the installed battery unit.
  • Optimum addition to wired communication and expansion of solution options for system solutions in process automation.
  • Burst mode and event notification parameterization for the adapter and connected field devices.
Область применения

The WirelessHART adapter can be used in a number of different applications, e.g.

  • Access to installed basis
    Diagnostic information is obtained from existing wired HART devices through a permanent electrical connection of a WirelessHART adapter, and is sent to an asset management software near the system, e.g. 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 accessibility or extensive costs for wiring. Better data flow and diagnostics increase the system’s reliability, transparency and safety.
  • Process optimization
    A temporary installation of a standard 4 ... 20mA or HART device together with the WirelessHART adapter SITRANS AW200 allows flexible monitoring and plant optimization at lower costs and reduced effort.
  • Process monitoring
    Measured values from e.g. tanks or silos are transmitted to a superordinate system in regular time intervals, together with the device and battery status.
Дизайн

The SITRANS AW200 WirelessHART adapter consists of

  • a housing with mounted antenna
  • electronics
  • a high-performance lithium battery unit

SITRANS AW200 Wireless-HART Adapter, assembly

The housing can be opened by loosening 4 screws. This allows to access the electronics and battery unit. The battery unit can be removed without the use of tools, since it is connected to the housing with clips.

The back of the housing features a connection part with a fixing nut onto which different replaceable connecting pieces can be screwed to mount the adapter directly on a field device.

The bottom of the housing contains an optional cable opening which can be used for a cable gland. In the case of an offset mounted adapter, it is possible to feed up to 2 cables.

SITRANS AW200 WirelessHART Adapter functional diagram

Measured values and diagnostic information of connected field devices with HART communication are transmitted via a wired connection to the WirelessHART adapter. The adapter transmits this information in the form of wireless signals to the

IE/WSN-PA LINK, the Siemens WirelessHART gateway. From here, the information is available to the network of the system.

Where a field device with a 4 ... 20 mA output signal is connected to the adapter, only the measured value will be transmitted.

Following parameterization 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 the neighbors in the wireless network. A WirelessHART network organizes itself. Manual settings for organizational purposes are not required.

Two- and four-wire field devices can be connected to a WirelessHART adapter. In the case of a connected two-wire field device, power can be supplied by the adapter. Where multiple two-wire field devices are connected (multi drop operation), the adapter must be connected to an external power supply.

The WirelessHART adapter may also be connected in parallel to an already existing installation which consists of a power supply and a HART field device.

Parameterization

The SITRANS AW200 configured via HART. This can be done using a handheld communicator or even more conveniently with a HART modem and the SIMATIC PDM parameterization software.

Initial start-up of the adapter is usually carried out via SIMATIC PDM and HART modem or a handheld communicator. During initial start-up, the network ID and join key is set up in the adapter, among others. Using these parameters, the adapter is then integrated into an existing WirelessHART network.

Once it is integrated into the network, the adapter and connected HART devices can be conveniently operated via the WirelessHART network or with the onsite HART modem.

Siemens HART field devices for the adapter

HART and 4…20mA field devices can be connected to the SITRANS AW200 WirelessHART adapter. Depending on the electrical data of the field devices, they can receive their power supply from the WirelessHART adapter or will require an external power supply. The table below illustrates the different options for Siemens HART field devices.
