GX Developer Special Relays

14 posts in this topic

HELLO TO EVERONE!!
Could someone please help me find a special relay command (not a real relay) that stays activated when it receives a pulse from a NO contact (X0), and desactivies when it receives a second pulse from the same NO contact (X0)?
So en conclusion I need to control a relay with only button.

I hope you understand me... Help please....

It's not a special relay, it's a program command.  There's an instruction for that.  Depending on the model Mitsubishi PLC, look for ALT or FF.

I redrew the ladder diagram to better understand it. I tried FF @Crossbow but for some reason my simulator goes into error. Q50UDEH CPU set on the project. Instead this seems to work just fine.

Easy peasy. Use ALTP. Will alternate M10:
-[M0]-----[ALTP M10]-

Thanks for the example kaare_t!!!

But I  have an other question... Why do you put a M0? Could I use a X0 instead of the M0?

Perhaps it's time for you to review some of the online training materials Mitsubishi offers.  Many of the questions you are asking can be learned in the online classes.  And they are free.
