D
Symbol:
Explanation:
1. The number of bits whose values are 1 in S is stored in D.
2. When the values of the bits in the source device specified by S are 0, the zero flag SM600 is
ON.
3. Only the 32-bit instructions can use the 32-bit counter.
Example:
When X0.0 is ON, the number of bits whose values are 1 in D0 is stored in D2.
Additional remark:
If the device exceeds the range, the instruction is not executed, SM0 is ON, and the error code in
SR0 is 16#2003.
