NOTE
Becarefulaboutthenoiseontheeldbuslink.Iftheeldbusisnoisy,thedownloadingmaytake
a very long time or fail.

Downloadleshavethefollowinglenames(withthelenameextensionof“.󰀨d”).Takecareto
choosethecorrectdownloadleforthetargetelddevice:
“594543” + device family + “_” + device type + “_” + domain name + “_” + software name +
“_”+softwarerevision+“.󰀨d”
Forexample,thenameofthedownloadleforFLXA21-PHmayhavethefollowingname:
5945430402_0402_FLXA21PH_ORIGINAL_R101.󰀨d
Referto(3)DOMAIN_HEADERinpageApp.2-8abouteachkeywordofthelename.
The device type is “0402” for FLXA21-PH, and is “0403” for FLXA21-SC.
Thesoftwarenameis“ORIGINAL”or“UPDATE.”Theformerindicatesanoriginalleandthe
latteranupdatele.Wheneverperformingadownloadtoupdatethedevicerevision,obtainthe
originalle.Ingeneral,anadditiontotheparametersorblocksrequiresadevicerevisionupdate.
n Steps after Activating a Field Device
Whenthecommunicationwithaelddevicehasrecoveredafteractivatingthedevice,check
usingthedownloadtoolthatthesoftwarerevisionoftheelddevicehasbeenupdated
accordingly. The value of SOFT_REV of the resource block indicates the software revision.
The PD tag, node address, and Sensor transducer block calibration parameters that are retained
in the nonvolatile memory inside the target device will remain unchanged after a software
download. However, after a software update which causes an addition to the block parameters or
blocks, or to the system/network management VFD parameters, some parameters may be reset
to the defaults, thus requiring parameter setup and engineering again. For details, see the table
below.
Also note that a change in the number of parameters or blocks requires the DD and capabilities
lescorrespondingtothenewsoftwarerevision.
Table 1 Actions after Software Update
