Pulse Log Entry

The Omnipod maintains a log in flash memory of 32-bit entries for each pulse delivery event during its operation. During normal use with a PDM, up to 100 of these pulse log entries (i.e., the last 5.0U of delivered) are read out by the PDM during Pod deactivation using the Status Request Type 80 and Type 81 which will return the 02 Response, Type 80 (0x50) and 02 Response, Type 81 (0x51) respectively. The Omnikit Command Tester will display the results of these pulse log entries which can be manually captured using the Read Pulse Log command or automatically captured when deactivating a faulted pod.

The 32-bit (dword) pulse log entries have the following form:

eeeeee0a pppliiib cccccccc dfgggggg
  • eeeeee0a
    • eeeeee = 6-bit unsigned encoder count (byte_71 & 0x3F)
    • a 1-bit pump driving flag, LOAD1=0 or LOAD2=1 (byte_11E & 1)
  • pppliiib
    • ppp = 3-bit pulse mode: 000=None, 001=basal, 010=temp basal, 011=bolus, 100=extended bolus (byte_35F & 7)
    • l = 1-bit low reservoir signal value ((PTBD & 8) != 0)
    • iii = 3-bit unsigned immediate bolus tick counter / 2 ((byte_280/2) & 7)
    • b = LoadCountVal & 1 (i.e., the low bit of the LoadCountVal)
  • cccccccc
    • cccccccc = LoadCountVal / 2 (if ppp != 0) or 0
  • dfgggggg
    • d = 1-bit last analog comparator read (byte_27B & 1)
    • f = 1-bit fault flag for validate_encoder_count() $4n fault with Tab5[0x10] == 0 (byte_B96 & 1)
    • gggggg = signed 6-bit last computed encoder value (last value from byte_BE3[] & 0x3F), 0 is nominal value

byte_280 is incremented on each 1/8 of a second tick during an immediate bolus and then reset to 0 when the pulse is delivered and the pulse log entry created. Since iii is byte_280/2, each higher value represents a quarter of a second and since iii is a 3-bit value, it can represents between 0 and < 2 seconds (which is the timing between pulses when delivering an immediate bolus).

LoadCountVal is an unsigned 9-bit adjusted & rounded load count value as given by the following calculation which essentially adjusts LOADCNT up by 2.45% and rounds up the result.

LoadCountCal = (((LOADCNT & 0x1FF) * 1000) + 488) / 976

byte_B96 is set in main_loop_control_pump() on a Pod fault where validate_encoder_count() returns a error which is not a 0x40 error with a non-zero Tab5[0x10]. Possible validate_encoder_count() errors:

  • $40 - count too high (> 30 or 34)
  • $41 - last 10 counts either too low or too high by 13
  • $42 - count too low (< 20)
  • $43 - other error

byte_BE3[10] is an array of 10 bytes which is indexed by byte_73. byte_73 is updated atomically and has a shadow verifier value. All of byte_BE3[] and byte_73 are summed and its complementary value saved in word_BED and used as for verification. byte_BE3[] is updated with byte_71 - 25 in validate_encoder_count() (nominally the encoder count should be 25). The last 10 counts are stored in byte_BE3[].

Example #1 0x6a basal fault with PDM

The Pod pulse logs reads are the largest messages returned from the Pod. Many of the capture logs are missing one of of the CON packets for these messages and thus do not have the full 50 32-bit pulse log entries. This analysis of the PDM request for the Pod pulse log entries at Pod shutdown was taken from 0.05 Insulin not delivered with deactivation after a 0x6a fault had occurred:

Since cccccccc = 62 and b = 1, LoadCountVal was 62 x 2 + 1 = 125 and LOADCNT was (125 * 976) / 1000 = 122. Since the last normalized encoder count (byte_71 - 25) was 0, the last byte_71 would have been 25.
