Change in Logic of interrupt input Signal (DVIT Instruction)

Turn the "Interrupt signal logic reverse" relay ON or OFF to specify the logic of the interrupt input signal of the
interrupt positioning (DVIT) instruction.

Caution:
If a user interrupt input command (M8460 to M8463) is specified in the interrupt input signal, the logic of the
user interrupt input command cannot be specified. This is because turning on the user interrupt input
command will turn on the interrupt input signal.

A device can only be specified if an FX
When using an FX PLC below Ver. 2.20, if "8" is set and then the specified interrupt positioning

(DVIT) instruction turns ON, an operation error (error code: K6763) will occur, and the instruction will
not cause any operation.

After setting a number in the range of 9 to E for the interrupt input signal, if the corresponding interrupt
positioning (DVIT) instruction turns ON, an operation error (error code: K6763) will occur, and the
instruction will not cause any operation.
