5.22 Counter
Counters can be created for )any specific event or for multiple events (see
). Counters function similar to an event and are independent of the event, thus
allowing g reater flexibility. You can select a counter for any event and if both channels
are selected you can set the counter to count upstream and downstream. Counters can
be reset providing further flexibility. The counter once set lives in the State. In an
Advance to Sequence state once the action proceeds from one sequence state to the
next, the counter in the preceding state will stop and the counter in the current state will
start.
There are two Counters for the Global State and four Counters for the Sequence State.
Note:
It is an invalid configuration for some events when you try and set a counter and timer
when both channels are selected.
The counters have different colors for the Global State and Sequence State. Each color
signifies a different meaning in the Global and Sequence states.
Note:
Global timers/counters can be used by events from any direction as long as the events occur
more than 380 ns apart. State timer/counters can be controlled only from one direction not
both, meaning starting, reset and incrementing must be done from events occurring in the same
direction of the selected timer/counter.
