Explanation
1. This instruction finds the number of bits in S whose values are ON and stores the number of ON bits in D.
2. When the values of all 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, but not the device E.
Example
When X0.0 is ON, the instruction stores the number of bits whose values are one in D0 in D2.

Additional remarks
If the device exceeds the range, the instruction is not executed, SM0 is ON, and the error code in SR0 is 16#2003.
