[V350 with IO-D16A3 output only reacts to initializing]

Hey,

i could resolve the issue with the info mode now.

The problem was, that in the startup routine the set password was overwritten - so i could access it now and actually test it - and it worked.

I then tried the online mode you suggested and i love it - such a handy tool.

Unfortunately now i'm even more confused than before.

The contacts a clearly connect, and i'm not receiving a warning about an unconnected element.

Forcing it to 1 works, so i guess it must be something else..

 

The only guess i have left is, that is has something to do with SB 177, which i imagine should be 1? But on the other hand why  should forcing it to 1 work then, so i kinda doubt this has something to do with my problem..

 

I attached you the current programm.

Once again thanks for you time.

BR, Nico

Hey, 

first off all thank you guys for your answers. I really appreciate you spending your time trying to help me out.

1. Please check subrouting call for used code.

2. Please Find O84 in code if any -(  )- coil used for it - S and -R Coil do not operate correctly.

3. Is it IO module connected to V350? It is not possible to simulate IO not connected to PLC.

4. You can go to Info Mode and try to operate  Outputs via Info Mode menu - Result?

 

1. You mean, whether the subrouting is being called / executed? If that is the case, then yes, i checked this via the "MB 10 light".

2. The only occurences of O 84 are in the subroutine that i posted.

3. The V350 is physically connected to an EX-A2X Extension Adapter which is then connected to the IO modules.

If there were no working connection between the V350 and the IO modules, then i would image that initializing the O 84 with 1 would also do nothing - but it does.

4. I tried entering the Info Mode but could not access it. It is password locked, "1111" did not work and unfortunately my friend does not know the password either. 

Then i tried setting the password via SI 253 - but i'm still not able to access info mode. After entering 1111 ENTER into the password mask, the password mask resets but keeps showing.

If you could provide me with information on how to reset the info password i would appreciate it.

On top of what Kratmel says, I would be changing the entire method.  Use a toggle coil that directly switches a single reference to O84.  Then use a Binary Text for the screen indication, based on MB7 (if you choose to keep that MB).

There might be other factors that make this impractical, but to me you are complicating things and also run the risk of instruction clashes due to using 2 separate MBs as controls.  Think your existing logic through, bearing in mind that the ladder always works on the last instruction that acts on an operand.

 MB7      O84

-(X)------(    )----

 

cheers, Aus

 

 

Thanks for the input, this seems like an smart idea and i changed the logic accordingly.

Sadly it had no effect on the elevator actually turning on.

Hello,

since I'm a developer i was asked by a friend of mine if i could have a look at his Vision 350 controller software.

I'm fairly new to this whole controller programming but decided to give it a try because it mostly seems pretty straight forward and also there is a community and also resources for it.

The setup is as can be seen on this screenshot:

Spoiler

I/Os have already been set up:

 

Now since i'm just getting started with this, my only goal is to get the elevator to run.

Which it does, if i initialize it with 1, like this:

 

However, i cannot manipulate its state via ladder programming.

 

I already checked if the MB 5 and MB 7 are working by adding a binary image switch linked to MB 10.

And the image switches just as i would expect it to, the elvator however always stays on the state that it was initialized at. 

 

I already search the forum but could not find any solution to this, but this seems like something that will be very obvious in hindsight.
