Flowserve 3400IQ - Manual (Page 2)

Logix 3400IQ Digital Positioner FCD LGENIM3403-00 – 11/07
Scope
This manual is provided for those users unfamiliar with fieldbus devices. It also provides documentation to fill
any gaps in information between fieldbus device user’s manuals and configurator software manuals. This
information is beneficial to those with a good understanding of the new and emerging fieldbus technology
but without experience using it.
This document was written to be used specifically with the Logix 3400IQ digital positioner. It is not meant to
replace the Logix 3400IQ Digital Positioner Installation & Reference Guide, or be a complete guide to the
fieldbus or NI Configurator software. This document will explain the steps necessary to configure and bench-
operate the Logix 3400IQ digital positioner. It assumes the user has the positioner mounted to an actuator,
tubed properly and with a good air supply. This document references the NI Configurator (version 2.3.6) as
the host tool.
Definitions
AI block: Analog Input block. This block receives an analog signal and converts it to a FF signal.
AO block: Analog Output block. This function block produces an analog output signal. This block controls
the input to a transducer block.
Configurator: Software tool used to access data and configure FF devices
DD: Device Description. Files used by configurator software or other FF host, which describes an FF device.
DDs allow for custom manufacturer specific features to be added to a FF device, and the host to have
access to those custom features.
FF: F
OUNDATION ™ fieldbus. Communications protocol used in the Logix 3400IQ digital positioner.
FINAL_VALUE: Fieldbus terminology for the positioner’s command signal.
Function Blocks: All FF device functions are divided into virtual function blocks. For example, if the device
is capable of performing PID control, a PID function exists.
FVPTB block: Flowserve Valve Positioner Transducer block. This block handles the configuration,
calibration and diagnostics for the Logix 3400IQ digital positioner.
Logix 3400IQ digital positioner: Flowserve’s F
OUNDATION fieldbus two-wire valve positioner.
mA: Milliamperes
PID block: Proportional, Integral, Derivative control function block
PV: Primary Variable or Process Variable
RS block: Resource block. This block contains basic FF information and configuration data
SP: Setpoint
VDC: Volts, Direct Current.
