From HART to WirelessHART

Wireless Commonly used in consumer

and office world Can be used in industry due

to technological progress Important: must be a standard

page 9

HART Used since 25 years 35% of all field devices use

HART Lot‘s of DCS and AMS have

HART interface Standard in Process

Automation

WirelessHART


From HART to WirelessHART Wireless is a new enhancement to the HART Technology Idea Keep the well known and proven protocol Change the physical layer from the modulated sine on the 4..20 mA loop

to radios and create the first wireless standard for PA

page 10


From HART to WirelessHART Objectives An open and interoperable standard As easy as using wired HART Enable wireless access to existing HART devices Use the same configuration, maintenance, diagnostic tools and

procedures Require little additional training Worldwide usable Hardware (radios) must be available from the shelf

page 11


Elements of WirelessHART As Radio Frequency the 2.4GHz ISM Band has been chosen

Advantages: Worldwide usable without any permission (some restrictions apply) Cheap and freely available hardware due to WLAN standard

IEC802.15.4

Elements of WirelessHART

The Elements of WirelessHART are: Flat mesh network Network management Frequency hopping Time Division Multiple Access (TDMA)

Mesh Network Topology

page 14

Mesh Network All network

participants form a mesh The range Broken paths Self healing


Network Management Network management The Network is organized and controlled by a central component, the

Network Manager The Network Manager

Forms the network

Determines the communication paths between all participants

Determines alternative paths and timings Newly added participants are added to the network automatically

Security and Integration of WirelessHART

WirelessHART is as usable as conventional HART products Therefore, also the layout of a communication structure does

not differ too much

All messages are encrypted with a 128Bit AES encryption key

The encryption keys are distributed and changed in certain intervals by the Network Manager
