Control Block Description
ADDvantage-32
4-14
4.11 ASM AUTO SHEET MARKER
This block sets an output bit high when the number of sheets cut equals an operator-
entered setpoint (MARK STPT). The output bit also goes high when the number of
sheets cut equals integer multiples of the setpoint. Therefore, every nth sheet sets the
output bit high. The output bit remains high for the number of sheets entered in
calibration as MARK HOLD; then the bit goes low. The internal counter resets when the
MARK RESET bit is high.
