**SOLVED** 2 problems within the FBD **SOLVED**

Can't figure now how I should do this.. 2 problems present.

Attached the LSC, and that will also have explanations of things on it.

1. Having some problem with things starting to happen at power on, before user pressing START.

2. Pressing STOP does not put everything to halt if the timers happen to be running.. STOP button only works in case the Q1 or Q2 would at the moment be ON.. 

Thanks for your help

Thanks!

but I suggest that you wouldnt move stuff around like that :D

Its hard to compare it to the old and even see what you did there then.

Also it now would not start at all if i4 is active, or if both i4 & i5 are active. It starts only if the i5 are active.

does those M1 & M2 -flags serve some purpose?

as those connections can be made without flags

Hi,

in LSC you can compare LOGO! programms. 

Open both version in LSC and then select Tool/Compare.

Hope this helps

1. Having some problem with things starting to happen at power on, before user pressing START.

2. Pressing STOP does not put everything to halt if the timers happen to be running.. STOP button only works in case the Q1 or Q2 would at the moment be ON.

to 1.) You negate the limit switch inputs on the NAND edges in your program.
If the LOGO! is started and a limit switch is not on 1 signal, the latching relay is set immediately and thus the time started, which then switches on the output.

to 2.) The STOP command in your program only affects latching on the relays B004 and B005.
But not on the latching relays B010 and B015. 

..I knew I should just go to sleep and look at it tomorrow.. Was I sure I had tried connecting the stop to those other latches too or whaaat the heck :-D
