Explanation of function and operation

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.
