Parameter Description
3.12.3 RS Flip Flops
The reset/set flip flops hold the signal until set/reset.
Par. 13-15
RS-FF Operand S
Par. 13-16
RS-FF Operand R
Illustration 3.42 Reset/Set Flip Flops
2 parameters are used, and the output can be used in the
logic rules and as events.

Flip Flop Output
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.
