6. Cycle Start Bit and Forced Block End Bit
Cycle Start Bit
Forced Block End Bit
Operation
The Forced Block End Bit is turned ON at the end of block N002, but the down-differentiation of the Cycle Start Bit
takes precedence, so the Forced Block End Bit is ignored. Program execution is restarted when the Cycle Start Bit
is turned ON again.
7. Cycle Start Bit and Forced Block End Bit
Cycle Start Bit
Forced Block End Bit
Operation
The Forced Block End Bit is turned ON to cancel execution of block N002 and stop program execution. Program
execution is restarted when the Cycle Start Bit is turned ON again.
8. Cycle Start Bit and Forced Block End Bit
Cycle Start Bit
Forced Block End Bit
Operation
The Forced Block End Bit is turned ON to cancel execution of block N002 and stop program execution. Even
though the Cycle Start Bit is turned ON again, the Forced Block End Bit is still ON, so program execution isn't
restarted.
9. Cycle Start Bit and Forced Block End Bit
Cycle Start Bit
Forced Block End Bit
Operation
The Forced Block End Bit is turned ON between blocks N002 and N003, so execution of block N003 is cancelled
and program execution is stopped.
