Wireless HART is a Wireless Mesh Network
designed to meet the needs for process
Wireless HART is a key part of the HART Field
Communications Protocol Revision 7
Existing HART applications (e.g., control
systems, PLC's, maintenance tools, and asset
Wireless HART Field Devices (WFD):
connected to the process or to plant equipment
Wireless HART Gateways:
enable communication between Host Applications
support one or more Access Points
A Gateway and its Access Points must included in
every Wireless HART network
A Wireless HART Network Manager:
responsible for configuration of the network
scheduling communication between Wireless HART
devices (e.g., configuring super frames)
management of the routing tables
monitoring and reporting the health of the Wireless
Maximum data rate (250 kbps).
Operating Frequency (2.4 - 2.48 GHz).
O-QPSK modulation and Direct Sequence Spread
transmit Power is 10dBm.
Wireless HART DLPDU (Data Link Protocol Data
Unit) specifies a byte which identifies Wireless HART
TDMA using timeslots organized into super frames
as 100 timeslots per second depending on the
Link between devices specified by super frames,
timeslots and channel offset.
Devices support routing and broudcast.
Configure the shared slots and blocking
provides end-end acknowledgement of
Acknowledged transmissions include automatic
retransmission to confirm successful data transfer.
Supports TCP-like reliable blocking for transmission
of large data sets.
Device status for quality process.
Commands aggregation for multiple
Wireless HART provides new capabilities and
more secure process.
The HART technology becomes the leader of
the wireless industrial networks.
