Function and system design
WirelessHART WirelessHART adds wireless capabilities to the HART protocol, while guaranteeing compatibility with
existing HART devices, commands and tools.
A WirelessHART network comprises:
• WirelessHART field devices
• Wired field devices with a connected WirelessHART Adapter
• Fieldgate
The WirelessHART protocol may not be used to replace the wiring in the case of safety applications
with a control function.
WirelessHART Fieldgate
SWG70
System design The WirelessHART Fieldgate stores information received from the WirelessHART Adapter SWA70
The WirelessHART Fieldgate SWG70 acts as an interface between the WirelessHART network and a
system that has an Ethernet or RS-485 connection.
The WirelessHART Fieldgate SWG70 supports the following functions:
• Wireless network configuration and management
• Acquisition of data from the field devices and presentation to connected systems
• MODBUS, HART, HART-IP, OPC and EtherNet/IP support for system integration
• Configuration of network, Fieldgate and field devices via Web interface or FDT/DTM.
Fieldgate is designed for installation in hazardous areas Zone 2. You can mount the antenna directly
on the Fieldgate or remotely depending on the requirements of the application.
or other WirelessHART field devices in a buffer which can be accessed by a host application via an
Ethernet or RS-485 connection. The figure shows a Fieldgate operating in a typical meshed WirelessHART network architecture.

Accessories
Antenna accessories Note the following when selecting accessories for the antenna:
• The Ex approval for Fieldgate SWG70 is only valid for the 2 dBi antenna supplied.
• The antenna must comply with the rules for the usage of 2.4 GHz equipment that apply in the
country of installation. In case of doubt, please contact a regional expert for radio approvals.
• The gain is calculated from the difference in the antenna gain and the losses of the individual
components such as the cables and surge arrester. The gain may not exceed the 2 dBi limit.
• The WirelessHART range of the Fieldgate SWG70 depends on the coaxial cable used (attenuation)
between the Fieldgate and the antenna.
