Other machinery (that is not visible) now automatically removes the object and the
proximity switch becomes inactive. At CV1 the drill-motor turns OFF and at CV0
the feed-motor is switched to move slowly until it reaches the limit switch and is
switched OFF (via the ladder program). At this moment a new object is placed in
position again. At this moment the feed-motor stays switched OFF for as long as
the proximity switch has detected a new object, initiating the whole cycle again.
The limit switch is connected to Digital Input I0 which is assigned function 05 (i.e.
Reset Rising Edge). Activation of the limit switch when the drill-motor is in the
home position causes Counter 1 to be reset and the feed-motor to be switched to
its initial state (slow/forward). An Output Reset Pattern (m+61, m+62) has been
defined to switch the feed-motor to its initial state.
DM-configuration
The Machine Number of the High-speed Counter Unit is 0. The High-speed Coun-
ter is allocated 40 CIO-words starting from CIO 2000 (n = CIO 2000 + 0 x 10) and
400 DM-words starting from D 20000 (m = D 20000 + 0 x 100). The Comparison
Data of Counter 1 is stored in EM starting from EM 1500. To configure the Unit the
following DM-settings must be made.
