Reset (EL5151 only)

The counter can be reset via “Enable C reset” (index 0x8000:01) or via “Enable extern reset” (index 0x8000:02). “Extern reset polarity” (index 0x8000:10) defines whether the reset takes place on a positive or negative edge at the external latch input.

“Enable C reset” (index 0x8000:01)

  • For activation the bit in “Enable C reset” (index 0x8000:01) is set to TRUE.
    The counter value is reset to zero if the zero pulse is present on channel C.

“Enable extern reset” (index 0x8000:02),

  • For activation the bit in “Enable extern reset” (index 0x8000:02) is set to TRUE.
  • “Extern reset polarity” (index 0x8000:10)
    • Bit not set: the counter is set to zero with a negative edge at the external latch input.
    • Bit set: the counter is set to zero with a positive edge at the external latch input.

The simultaneous activation of the functions “Enable C reset (index 0x8000:01) and “Enable extern reset” (index 0x8000:02) is not possible.
