how to toggle a bit using ladder logic?

MINKU

hello
i am using 1214c cpu and programming through TIA v11 sp2,
[schnippschnapp]
[3] how to toggle a bit using ladder logic, i am facing problem in this logic of toggeling the bits. will you give me some tip or program for that, it will be appreciated.


thanks and regards

in LAD

Toggle_Bit                             TOGGLED_BIT        BTmp
-----|P|----------------------------------|\|---------------()
FP_TOGGLE_BIT             |              BTmp     TOGGLED_BIT
                          |---------------| |----------(S)
                          |
                          |              BTmp     TOGGLED_BIT
                          |---------------|\|----------(R)

 BTmp is a bool Temp

TOGGLED_BIT is STAT or Memory Bit or DB

FP_TOGGLE_BIT is STAT or Memory Bit or DB which is used for edge detection

Thanks Piotr.M for the diagram. 

There needs a little change in your diagram. I tried it and it works well.

Hi there,

Just for fun :)

Two other solutions:

Hello. Here is the way i do it.

- The P_TRIG needs to be a global memory, not a local one.
- Every application of this code needs a individual memory bit for P_TRIG.
- The tag i have named #output cannot be an actual output memory, like Q0.0.
