4.1.1 SC Unit Input Monitoring
Monitoring is carried out by the byte unit. When the host computer gives the necessary address to AVK3, the
address status is returned from the AVK3 to the host computer.
However, even if the monitoring is commanded from the host computer while AVK3 is returning to the origin
of X-Y-Z axes, the program is not executed. The monitoring is executed only after completion of origin
return.
