24-Bit Counters Non-Quadrature Mode Outputs (continued)
In non-recycle counting mode, Compare, Carry , and Borrow pulses are not
generated. Carry Toggle and Borrow Toggle signals are the cycle completion
indicators. At the end of a cycle, additional input count pulses are ignored.
One of the following conditions is required to restart the counter:
• An external INDEX pulse (when WY21.07, or WY27.07, or both are
set).
• A PLC counter reset (WY19.02 or WY19.06).
• Setting the program flag (WY20.01).
In Divide-by-N counting mode, Compare, Compare Latch, or Compare
T oggle signals are not generated. The counter starts at the preset value and
counts to an overflow or underflow, generating a Carry or Borrow .
W e recommend that Divide-by-N counting be done in the down count
direction only , with the Borrow T oggle signaling the underflow event. In the
non-quadrature, recycle counting mode, the Carry and Borrow pulses are
externally available, and can be used to cascade to another counter input.
