Inputs The input data type is selected by the user.
Input (I): INT, DINT
Number of bits (BITCNT): INT; DINT
Outputs Output (O): INT; DINT
SHR
(10016)
Illustration
Execution time 0.80 µs
Operation Input bits (I) are rotated to the right by the number (N) of bits defined by BITCNT. The N
least significant bits (LSB) of the input are lost and the N most significant bits (MSB) of
the output are set to 0.
Example: If BITCNT = 3
Inputs The input data type is selected by the user.

Number of bits (BITCNT): INT; DINT
Outputs Output (O): INT; DINT
XOR
(10017)
Illustration
Execution time 1.24 µs (when two inputs are used) + 0.72 µs (for every additional input). When all
inputs are used, the execution time is 22.85 µs.
