*1 If an operating module in which "Not Detected" is selected in the parameter is removed, a module verification error is not detected;
however, a stop error may occur if accessing the removed module by using programs, etc. Since the removed module is not accessible
even if it is mounted again, accessing the module by changing the module status from STOP to RUN may result in a stop error.
