Limit Comments
32 When the limit is exceeded, an error indica-
tion is output by the device. Consequently,
the device starts monitoring. The red
ERROR-LED lights up.
16 Only error message
(Evolving error in processing procedure)
400 When the limit is exceeded, an error indica-
tion is output by the device. Consequently,
the device starts monitoring. The red
ERROR-LED lights up.
400 Only error message; 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 indica-
tion is output by the device. Consequently,
the device starts monitoring. The red
ERROR-LED lights up.
