6SE6400-5BB00-0BP0
Example:
P2115[0] = 13625
P2115[1] = 2579
P2115[2] = 516
The conversion into binary quantities (U16) results in the following bit pattern:
Seconds + minutes:
-
High byte (MSB) = 00110101 corresponding to the number 53, i.e. seconds 53
-
Low byte (LSB) = 00111001 corresponding to the number 57, i.e. minutes 57
Hours + days:
-
High byte (MSB) = 00001010 corresponding to the number 10, i.e. hours 10
-
Low byte (LSB) = 00010011 corresponding to the number 19, i.e. days 19
Months + year:
-
High byte (MSB) = 00000010 corresponding to the number 2, i.e. months 2
-
Low byte (LSB) = 00000100 corresponding to the number 4, i.e. years 4
This means that the real time displayed in P2115 is 19.02.2004, 10:57:53.

Def:
0
P-Group: ALARMS
Active: Immediately
QuickComm.: No
Max: 65535
Indicates total number of alarm events. This parameter is incremented whenever an alarm event occurs. It
also gets incremented when a warning is cleared or faults are cleared.
This parameter is used by the PC tools.
