When con ertin a COL ECTION into a Stru tDataGroup, the DataItems s al b identical to

the COL ECTION memb rs with:

The SemanticInfo for HART protocol related p rameters is directly related to the protocol

The s ntax of the p rameter ad res inf ormation is as folows:

HART s p orts variou typ s of ph sical layers l ke HART FSK, HART over Ethernet, HART

that a HART Network contain a gateway device whic con ects nodes s p ortin diff erent

ph sical layers One example for s c gateway device is the Wireles Ada ter whic al ows

con ectin HART FSK devices in a Wireles HART network

Another example for s c gateway device is a HART Inf rared Ada ter, whic may con ect a

HART FSK device to a HART Inf ared Network

It is p s ible that some ada ters a p ar to b tran p rent, i.e they do not act as HART

Nodes on the network They act as ph sical layer ada ter, imp rsonatin the device they are

con ected to Althou h, c r ently there are no Tran p rent Gateway in the market, the HART

protocol do s not restrict the p s ibi ty of s c Tran p rent Gateway /Con erters in the

network

IEC TR 6 4 3-4 req ires that s c tran p rent gateway /ada ters are re resented by a

DTM

With the def i ition of new protocol Id for e c of the HART typ s in order to cre te a

HART network

It is man atory that every p rticip tin node in the ph sical network s al have a DTM
