Out and OutNot
z OutNot
The OutNot instruction takes the inverse of the logical result from the previous instruction and outputs it
to a specified BOOL variable.
The following figure shows a programming example and timing chart.
• The Set and Reset instructions operate only when the input value changes to TRUE. They do not
operate when the input value is FALSE. When the input value is FALSE, the output does not change.
• The Out and OutNot instructions affect the output whether the logical result of the previous instruction
is TRUE or FALSE.
