2 parameters are used, and the output can be used in the
logic rules and as events.

Illustration 3.43 Flip Flop Outputs
The 2 operators can be selected from a long list. As a
special case, the same digital input can be used as both
set and reset, making it possible to use the same digital
input as start/stop. The following settings can be used to
set up the same digital input (for example, DI32) as start/
stop.
