During normal operation, test routines are run continuously.
menu item
2.1
The display ”OK” appears in the case of error-free operation after
selecting the menu item 2.1 (device status). An error message is
displayed in clear text in the event of an error. The possible error
messages are listed in Table 5-2 and the assignment of the error
messages to the individual outputs specified. The error message can
only be output via the digital outputs 1 and 2 and the analog output if
configured accordingly (selection of ‘Alarm’ function for the digital
outputs or ‘Failure signal’ for the analog output) (see menu items
4.1.2
,
4.2.1
and
4.3.1
).
A flashing ”F” appears for process related errors or a flashing ”D” for
device errors in the first line at the top right of the display when errors
occur. Should errors in groups ’F’ and ’D’ occur at the same time, only
’D’ will flash.
In communication via PROFIBUS the diagnostic message displayed
here is also reported under the extended diagnosis with the diagnostic
bit ”EXTENSION_AVAILABLE” (see section
5.4.3
).
