Troubleshooting overview

This section contains information to help you identify the faults in devices and the
recommended actions to correct them. Troubleshooting is performed to determine the cause
of the fault by analyzing the device indications (such as device not visible on network or
not able to write values to parameters.)

Device status and faults

The transmitter constantly runs internal background diagnostics to monitor the functions
and status of the device operations. When errors and/or faults are detected, they are
reported in the status bits of certain block parameters, (for example, BLOCK_ERR). The
other parameters can be seen by viewing the status descriptions and/or a value, which may
help to identify a fault.
Device status and operational faults are identified by viewing key parameter values or
status and then interpreting their meaning using the following tables.
ATTENTION
Additional diagnostics are available through supervisory and control
applications that monitor and control fieldbus networks. These diagnostics
and messages are dependent upon the capabilities of the application and the
control system that is used.
