Execution time 1.55 µs (when two inputs are used) + 0.60 µs (for every additional input). When all
inputs are used, the execution time is 19.55 µs.
Operation The output (OUT) is 0, if all connected inputs (IN) are 0. Otherwise the output is 1.
Truth table:
The inputs can be inverted.
Inputs The number of inputs (2…32) is selected by the user.
Input (IN1…IN32): Boolean
Outputs Output (OUT): Boolean

Execution time 1.28 µs
Operation Input bits (I) are rotated to the left by the number (N) of bits defined by BITCNT. The N
most significant bits (MSB) of the input are stored as the N least significant bits (LSB) of
the output.
Example: If BITCNT = 3
Inputs The input data type is selected by the user.
Number of bits input (BITCNT): INT, DINT
Input (I): INT, DINT
