Load HMI and executing a FB with the same button

Recommended Posts

Hi everyone!

I'm having a problem when I try to make the line I attached works. 

MB151 is just a simple graphic button (that's not toggle). When I press it, it doesn't fill the vector with zeros, it only load the HMI display.

But if I delete the command to load the HMI display, it works properly. What can be wrong?

Thanks in advance!

 

PS: I'm using a V350

Break your logic up into two rungs. I have regularly seen problems with HMI calls interfering with the rest of the logic in a single ladder rung. There is no reason not to place the HMI call in the next rung, also preceded by MB151.

Thanks Flex, but I've already tried that and it didn't work.

Anyway, I replace the FB with a Direct Coil (MB152), and I assigned in another rung, a Positive Transaction Contact (Rise) of the MB152 to the FB and it's working now!

I think it's a kind of bug of the VisiLogic.

Thanks again Flex!!

Cheers
