instruction is already used in another instruction.
2) The interrupt signal device for a DVIT instruction is
outside the allowable setting range.
1) Check to make sure the input (X), as specified by a
DSZR, DVIT or ZRN instruction, is not being used for
the following purposes:
- Input interrupt (including the delay function)
- High-speed counter C235 to C255
- Pulse catch M8170 to M8177
- SPD instruction
2) Check the contents of D8336 for the correct interrupt
signal specification for a DVIT instruction.

Pulse output number is already used in a positioning
instruction or pulse output instruction (PLSY, PWM,
etc.).
Check to make sure the pulse output destination is not
being driven by another positioning instruction.
