Param Name Config Var Type Description
EN Enable no - The state of the rung (off/on)
received from the left.
ENO Enable
Out no - The state of the rung (off/on)
passed to the right.
IN1 Input
Value 1 req any integer*
T_DONE
T_VALUE
T_PREVAL
The first input value.
IN2 Input
Value 2 req any integer*
T_DONE
T_VALUE
T_PREVAL
Numeric
The second input value.
OUT Output
Value req any integer* The result of a bit-for-bit XOR
comparison between the input
values.
* Any Input, Output, or Memory tag except 32-bit Real (F). For more information, see “ Defining Input,
Output, Memory tags ” on page 114 .
NOTE: No restrictions are placed on the sizes of inputs or output variables. If the
inputs differ in size (for example, an 8-bit byte compared with a 16-bit word),
then the smaller input is bit-extended with zeros to match the size of the larger
input.
Furthermore, if the result is larger than the output variable (for example, a 16-bit
result to be placed in an 8-bit output variable), then the high-order bits of the
result are discarded and the low-order bits are placed in the output.
C.5.4 Not (NOT)
When used in a Ladder Diagram, the NOT block performs a bit-for-bit inversion
upon an input and sends the result to output.
Select the tool (from the Logical and Bit Shift Blocks toolbar) and click on a
ladder rung to insert the following block:
Once the block is inserted, you can double-click on it to configure it.
