Technical Information
WirelessHART Adapter SWA70
Intelligent WirelessHART interface module
for connection to 4...20 mA/HART devices
Application
WirelessHART Adapter SWA70 is a battery powered,
interface module that connects HART and 4...20 mA
devices to a WirelessHART network. The adapter is
suitable for several applications, for example:
• Tank and silo monitoring/Inventory control:
Measured values together with device and battery
status are transmitted at regular intervals to a higher
level system
• Access to installed base:
Additional diagnosis information is extracted from
existing wired HART devices and sent to a plant asset
management tool, e.g. FieldCare
• Condition monitoring of equipment:
Wireless devices are added at critical points in the plant
not normally connected to the control room due to
accessibilty or wiring costs. Improved data flow and
diagnostics increase plant reliability and safety.
• Process optimization:
Temporary connection of the WirelessHART Adapter
allows plant sections to be monitored and optimised at
little cost and effort.
Features and Benefits
• HART devices quickly upgraded to WirelessHART
technology
• 4...20 mA devices quickly integrated into the
WirelessHART network
• One 4...20 mA or up to four HART devices can be
connected (in multidrop mode) to one adapter
• Burst mode and event notification supported for
adapter and connected devices
• Remote and difficult-to-access HART devices
connected to the plant control room without
expensive cables
• Tanks and silos integrated at minimal cost into
e.g. SupplyCare Inventory Control software
• Endress+Hauser and 3rd party devices maintainable
with open FieldCare Plant Asset Mangement software
• Network configuration also done within FieldCare
Plant Asset Management software
• Supports configuration with FDT and DD-based
network tools

WirelessHART Adapter SWA70
Function and System Design
WirelessHART
WirelessHART is a HART Communication Foundation specification for use in process automation. It adds
wireless capabilities to the HART protocol while maintaining compatibility with existing HART devices,
commands, and tools.
A WirelessHART network comprises:
• Wireless field devices
• Non-wireless field devices enhanced by using a WirelessHART adapter
• Gateways that enable communication between devices and host applications
• A Network & Security Manager responsible for configuring, managing and monitoring the network
WirelessHART Adapter
SWA70
Endress+Hauser’s SWA70 WirelessHART Adapter has been designed to act as an add-on interface for any
HART or 4...20 mA device. It supports the following functions:
• Powering of one HART or one 4...20 mA device;
alternatively, connection of up to four externally powered HART devices in multidrop mode
• Scaling of current signal supplied by a connected 4...20 mA device
• Burst mode and event notification for both itself and the connected devices.
The battery has been specially selected to give long life when used in monitoring applications.
System design
WirelessHART Adapter SWA70 transmits its information to a host application through a WirelessHART
Fieldgate. The figure below shows a typical meshed WirelessHART network architecture.
