21.4 Warning Status and Warning Status Application
The current warning is displayed by a message in the warning status and can be
used for an early message of a critical operational condition. If a warning is present,
this is indicated by the flashing red LED and the display f
ield WARN of the control
unit. If several warnings are present, the warning status is displayed as the sum of
the individual warning codes.
The warning masks created through parameters Create warning mask 536 and Cre-
ate warning mask application

have no influence on the warnings displayed. Via
the actual value parameters Warning 269, Application Warnings 273, Warning
status
356 (in error environment) and Warning status application 367 (in error envi-
ronment), all warnings present at the time of the error are always displayed.
