Figure 66: 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.
