4 : When using a special high-speed output adapter for the pulse output destination in an FX
direction signal must be used by the following table output.
When using a built-in transistor output for the pulse output destination in an FX
direction signal must use transistor output.

FNC150
DSZR
Caution on writing during RUN
During RUN, avoid writing while the DSZR (FNC150) instruction is executed (that is, while a pulse is output).
Note that if writing is executed during RUN to a circuit block including the FNC150 instruction while pulses are output,
the PLC decelerates and stops pulse output.
Function change depending on the version
The function of FNC150 instruction is changed depending on the version as shown in the table below.
