DVIT
Caution on write during RUN
Avoid write during RUN while the DVIT (FNC151) instruction is executed (that is, while a pulse is output).
Note that the PLC decelerates and stops pulse output if write during RUN is executed to a circuit block
including the FNC151 instruction while pulses are output.
Function change depending on the version
The functions of FNC151 instruction are changed depending on the version as shown in the table below.

Outline of function
When M8336 is set to ON, the interrupt input signal corresponding to
Y000 to Y003 is changed to an input number (X000 to X007)
specified by D8336.
When using a transistor output in the main unit, Y003 cannot be
specified.
When "8" is specified by D8336 to the interrupt input signal
corresponding to Y000 to Y003 and M8336 is set to ON, the interrupt
input signal is changed to a special auxiliary relay.
changed special auxiliary relay is set to ON from OFF in an input
interrupt program, the PLC starts the interrupt operation. When this
function is used, however, the logic of the interrupt input cannot be
inverted.
When using a transistor output in the main unit, Y003 cannot be
specified.
