Siemens MICROMASTER 440 - Indication Counter; Hysteresis Frequency F_Hys; Time-Constant Frequency Filter

Parameter Description Issue 01/06
MICROMASTER 440 Parameter List
210 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.
P2120 Indication counter Min: 0
CStat: CUT Datatype: U16 Unit: - 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.
P2150[3] Hysteresis frequency f_hys Min: 0.00
CStat: CUT Datatype: Float Unit: Hz Def: 3.00
P-Group: ALARMS Active: Immediately QuickComm.: No Max: 10.00
Defines hysteresis level applied for comparing frequency and speed to threshold as illustrated in the
diagram below.

P2153[3] Time-constant frequency filter Min: 0
CStat: CUT Datatype: U16 Unit: ms Def: 5
P-Group: ALARMS Active: Immediately QuickComm.: No Max: 1000
Specifies time constant of first-order frequency filter. The filtered frequency is then compared to the
thresholds.
