Function

SITRANS AW210 WirelessHART Adapter, functional diagram

The measured values and diagnostic information from the

connected field devices with HART communication are trans-

mitted 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, synchro-

nizes 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 instal-

lation 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 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 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
