Technical Assistance
If the user encounters a problem with the Logix 3400MD digital positioner, the configuration of the Logix 3400MD digital positioner should
be checked to verify that all selections are consistent with the application. If the problem persists, call your local Flowserve representative or
Flowserve Digital Products support listed in the contact information at www.valvesight.com.
Do not return a Logix 3400MD digital positioner without authorization from Flowserve Product Technical Assistance, or until an RGA (Return Goods Autho-
rization) has been issued by Flowserve.
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:
<DEV_REV><DD_REV>.ffo
<DEV_REV><DD_REV>.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 ex-
ample below is of the resource block for a Flowserve Logix 3400MD 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.
