Built-in Positioning Functions
*1. A device can only be specified if an FX
When using an FX
(DVIT) instruction turns ON, an operation error (error code: K6763) will occur, and the instruction will
not cause any operation.
*2. Devices related to Y003 (pulse output destination) are only valid if two FX
connected to the FX
*3. 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.
Example program:
The following program specifies the interrupt input signal for each pulse output destination device as shown in
the following table.
Pulse output

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.
