To add an enable input and enable output to the instruction, select [With EN/ENO] from the
"Instructions" pane (LD, FBD or IL editor). To reuse an instruction select "Recently used" from the
context menu or press <Ctrl>+<Shift>+<v> in the programming window.
For SR declare the following:
SET (S1) Set
The output Q is set for each rising edge at SET
RESET (R) reset
The output Q is reset for each rising edge detected at RESET, except
when SET is set (see time chart)
Q (Q1) signal output
is set if a rising edge is detected at SET; is reset if a rising edge is
detected at RESET if SET is not set.
 The names in brackets are the valid parameter names of the ST-editor.
 Q is set if a rising edge is detected at both inputs (Set and Reset).
 Upon initialising, Q always has the status zero (reset).
