Fieldbus Device Version Checking
To assure the proper operation of the fieldbus device, always make sure the DDs loaded in the host
configurator’s library are the correct ones for the hardware version. Several different hardware
versions of your fieldbus devices can possibly reside on various segments at the same time. Fieldbus
Foundation has provided a means to tell which version of DD is needed for a particular device in its
resource block.
The resource block contains the following standard parameters:
MANUFAC_ID-- This contains the manufacture’s Fieldbus FoundationÔregistration ID number.
Make sure this number matches the device used.
DEV_TYPE-- This is the Foundation registered device type to designate what kind of device it is.
Make sure the device type is correct for the unit.
DEV_REV-- This is the current revision of the device.
DD_REV-- This is the required DD revision level for this device. Make sure the DD supports this
revision level. An improper DD may cause unexpected operation or inability to use certain
features.
The DD files used with the host have names derived from DEV_REV and DD_REV as follows:
.ffo
.sym
Example: IF DEV_REV is 0x01 and DD_REV is 0x03, then the DD files would be 0103.ffo and 0103
sym.
In addition to these Fieldbus Foundation specified parameters, some manufactures may add
additional device version information. The example below is of the resource block for a Flowserve
Logix 3400IQ digital positioner. The revision array is an optional resource parameter, but gives
additional information about the internal firmware code versions. This array resides at the bottom of
the parameter listing.
MANUFAC_ID: This should always equal a 0x00464c53 (4607059), which is Flowserve’s FF
Manufacturer ID number. Converting this number to ASCII will produce FLS.
DEV_TYPE: This will be 0x0202. This tells the configurator that the device is a Logix 3400IQ digital
positioner.
DEV_REV: This is the revision level of the device.
DD_REV: This is the revision level of the DDs.
REVSION_ARRAY: Three elements can be found in REVISION_ARRAY. Element number 1 (closest
to the top) is the fieldbus (Honeywell) embedded software version. Element number 2 is the boot
code revision level. The final element is the positioner embedded code revision.
