10.1 Introduction
About This Section
This section contains information about identifying device faults and suggested actions to correct
them. The approach to troubleshooting is determining the cause of the fault through definition of the
symptoms (such as a device not visible on network or not able to write values to parameters).
The information is organized the following way:
Device troubleshooting tables list some of the more commonly encountered faults and sugges-
tions to check in order to find out where the problem is and correct it.
Positioner status tables define some of the conditions that cause critical or non-critical faults in
the transmitter. Critical and non-critical faults are described and suggestions are given on where to
find further information.
Device diagnostics briefly explains about some of the background diagnostics that are active in the
device during normal operation. Device parameters are described that provide information about
hardware and software status within the device.
Block configuration errors summarize conditions within the device which may be caused by
configuration errors and suggestions on where to look to correct the errors.
Simulation mode describes how to set up the transmitter to generate a user-defined simulated
input. This feature is useful in debugging the system when the process is not running.
10.2 Overview
Device Status and Failures
Logix 3400IQ digital positioner is constantly running internal background diagnostics to monitor the
functions and status of device operation. When errors and failures are detected, they are reported in
the status bits of various parameters in each block object, e.a. BLOCK_ERR or ERROR_DETAIL. Other
parameters can be viewed showing a status description and/or a value which may identify a fault.
Device status and certain operational faults are identified by viewing the parameter status or values
and interpreting their meaning using the tables in this section.
