Figure 7 shows another example of connecting an event counting
application to the STP340 screw terminal panel using user counter 0.
In this example, a software gate is used to start the event counting
operation.

Terminal Panel without an External Gate Input (Shown for Clock Input 0)
Figure 8 shows an example of how to externally cascade two counters
to perform an event counting operation using user counters 0 and 2.
Note that you can also internally cascade counters using software; if
you internally cascade the counters, you do not have to make the
external cascading connections. Note also that this example shows
the use of an external gate; however, this connection is not required.
