Counts the number of bits in the ON state (1) in the 32-bit data specified by s if the trigger EN is in the ON-state.

Parameters

Input

s (DWORD, DINT, UDINT, DATE, TOD, DT)

Source

Output

d (INT)

Destination area for storing the number of bits in the ON (1) state

Remarks

• Instead of using this F instruction, we recommend using the corresponding FP7 instruction: FP_COUNT_TRUE_BITSFP_COUNT_TRUE_BITS

• The number of 1 (ON) bits is stored in the 16-bit area specified by d.
