Designation Description
STS_ND Status zero crossing
Set on crossing zero in counter range when
counting without main direction.
STS_UFLW Status lower count limit
Set if the count value goes below the lower count
limit (→ “Object 6C01hex - Work Area Low Limit“).
STS_OFLW Status upper count limit
Set if the counter goes above the upper count limit
(→ “Object 6C02hex - Work Area High Limit“).
STS_CMP2 Status comparator 2
This status bit indicates a comparison result for
comparator 2 if:
The output DO2 is released with CTRL_DO2 = 1
and via Function DO2:
001: On when cnt. value f ref. value
010: On when cnt. value F ref. value
011: Pulse if cnt. value = ref. value
A comparison is executed.
Otherwise STS_CMP2 simply indicates that the
output is or was set. STS_CMP2 is also set if DO2
SET_DO2 = 1 when the output is not released.
