Technical Information
WirelessHART Fieldgate SWG70
Intelligent WirelessHART gateway
with Ethernet and RS-485 interface
Application
Fieldgate SWG70 is a gateway for
networks. It enables WirelessHART
cate with each other and manages network security and connectivity. Fieldgate converts and saves the wireless field device data
to a format that is compatible with other systems.
It has Ethernet and serial interfaces to connect to host applications such as SCADA tools.

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.

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.
