Alternate activation of two functions
An implementation option of alternate activation of two functions with each positive edge of
an input signal is shown by the following listing:
OB 1 (excerpt)
CLR
U E 1.3 // (1) If positive edge of user softkey U2?
FBD G 102.1
= G 102.3
UN G 102.3
SPB M007
CLR // (1) THEN
U G 102.2 // (2) IF Flip-Flop == 0 ?
SPB M006 // (2) THEN
..... // Activate Function 1 (e.g. display)
I G 102.2 // Flip-Flop = 1
SPA M007
// (2) ELSE (Flip-Flop == 1)
M006: .... // Activate Function 2 (e.g. switch-off)
R G 102.2 // Flip-Flop = 0
// (2) ENDIF
M007: NOP 0 // (1) ENDIF
