rung position question (by Alex)
hello i am making a ladder for a specific proyect, for this question i want you to see rung 1(ladder attach ldmicro5.4.0.4) , that rung doesnŽt work until i change to a higher rung number, i just want to mention that the only 3 elements in rung 1 are :
xlevanta_pata (it is used only there) yhabilitar (its main coil is only in rung 5) yarriba(this one is also declared in rung 7)(so i have 2 yarriba outputs declared in the ladder)

LDmicro runs from top to bottom, so Yarriba takes always the state of rung 17.
If rung 1 is true then /yarriba is only true until ldmicro arrives at rung 17. You need a oscilloscope to see that puls.

Thanks for your reply, I don't have an oscilloscope, I guess I can simulate one

I think you better change your program, do not use the same relay twice unless it is a set/reset relay, or if you intend to make a very short pulse.

thanks for your reply, yes iŽll change it
