Overview of online diagnostics
Online diagnostics means diagnostics during ongoing operation. During operation of the
positioner, a few important values and parameters are continually monitored. In configuration
mode, you can configure that monitoring so that the fault message output will be activated if,
for instance, a limit is exceeded.
Information about what events can activate the fault message output can be found in the
table in section "Overview of error codes (Page 224)".
This section contains particular information about the following situations:
● Possible causes of the fault message.
● Events which activate the fault message output or alarm outputs.
● Settings of parameters needed for event monitoring.
● Cancelling an error message
When the fault message output is triggered in "Automatic" or "Manual" mode, the display
shows which fault triggered the message. The two digits on the lower left show the
corresponding error code. If multiple triggers occur at the same time, they are displayed one
after the other cyclically. The device status, including all fault messages, can be called up
using command "#48" over HART.
