9.1.1 Input Parameters for the Shift Left Instruction
This table lists the inputs for the SL instruction and the variable type and data
type/range that each input supports.
Parameter Description Variable Type Data/Type Range
EN While this input is true, the instruction executes. When this
input is false, the instruction is not executed and ENO is
false.
Connect a Boolean input or output.
In Enter the name of the variable containing the bits you
want to shift.
D Boolean array
D simple integer or
double integer
D element of an
integer or double
integer array
D 1 or 0
D integer (0ĆFFFF)
D double integer
(0ĆFFFFFFFF)
BIT This input provides the state of the least significant bit
after the shift occurs.
To place a 1 in the least significant bit location, the
Boolean parameter connected to BIT must be true.
To place a 0 in the least significant bit location, the
Boolean parameter connected to BIT must be false.
If no Boolean parameter is programmed, a 0 is loaded
into the least significant bit location.
Connect a Boolean input or output.
