Broken wire

[M.R.Faiz]

Hello all, help me.

I'm trying to make a close-loop control for motor speed with a labview-multisim co simulation. For open loop it works well, but if I add a summation for close loop / feedback, the wire is broken by the cross marking wire. What's the solution?

Source codes are in the attachment.

Hello Faiz, 

If you can post screenshots of your code and the broken wire that would be more helpful.
