5 SEQUENCE INSTRUCTIONS
5.2 Association Instructions
• The INV instruction operates based on the results of calculation made until the INV instruction is given.
Accordingly, use it in the same position as that of the AND instruction. The INV instruction cannot be used at
the LD and OR positions.
• When a ladder block is used, the operation result is inverted within the range of the ladder block. To operate
a ladder using the INV instruction in combination with the ANB instruction, pay attention to the range that
will be inverted.
For details of the ANB instruction, refer to Page 138 Ladder block series connection, ladder block parallel
connection.
