Siemens 440 manual P2120 Indication counter, P21503 Hysteresis frequency fhys, 210

Parameter Description Issue 01/06

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.

Level

4

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.
