(Note2) If an attempt is made to remove the check from parameter and write sequence programs during PLC
is running, the prompt "PLC is running. Do you want to force write of the files?" is displayed.
The CNC only supports writing during RUN from the [Compile] menu; if [Yes] is clicked, an error
dialog is displayed and sequence programs are not written.
Click [No], and click [Yes] to the prompt: "The CPU status must be STOP to perform a write
operation. Would you like to perform write operation?"
