Limit Comments
32 When the limit is exceeded, an error message is output by the
device. Consequently, the device is put into monitoring mode. The
red ERROR-LED lights up.
16 Only Error Message
(record in device fault log, evolving fault in processing procedure)
400 When the limit is exceeded, an error message is output by the
device. Consequently, the device is put into monitoring mode. The
red ERROR-LED lights up.
400 Only fault annunciation (record in device fault log); here the
number of elements of the left border per task level is counted.
Since the same information is indicated at the border several
times, only unequal information is to be counted.
350 When the limit is exceeded, an error message is output by the
device. Consequently, the device is put into monitoring mode. The
red ERROR-LED lights up.
Limit Comments
50 When the limit is exceeded, an error message is output by the
device. Consequently, the device is put into monitoring mode. The
red ERROR-LED lights up.
