SITRANS AW200 WirelessHART adapter

Terminal block with 6 screw connection clamps
Parameterization
SITRANS AW200 configured via HART. Configuration can be
carried out using a handheld communicator or, more conve-
niently, 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 communica-
tor. 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 with the local 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.

Siemens has only approved the Siemens HART field devices
listed there for the adapter, and will only provide technical sup-
port for these devices.
Based on HART specifications, it is generally possible to con-
nect devices that are not listed, however with the following limi-
