Implmenting IF condition in FBD

Hello, I am writing a POU in FBD using CoDeSys. I want to implement an IF condition in one network of FBD editor to jump to another network if result of IF condition is true.

I do not know how to implement IF condition in network and how to assign the result to JUMP label?

You don't explicitly insert an 'IF' statement in FBD, it's more of an implied function when using a combination of AND, OR, NOT, etc. When you place an AND block and connect variables to it, you'll read it as "IF variable1 AND variable2, THEN...".

Insert a jump in FBD using the C-L button, or by pressing Ctrl+L

What I want is that if result of IF condition is TRUE, then my program should JUMP to another network rather than going to next network However, what I am facing is that even if output of AND is false, my program is JUMPING to the other network instead of going to next Network... What should I do to correct it?

Can you upload a screenshot of your program?

What I want is that counter should reset after CV equals PV..and AND condition should then go to label: con

Just place your 'control' variable on counter.Q. Or place counter.Q on the RESET input. Then, network 3 and everything currently downstream of the counter.Q can be deleted.

One other thing..
The AND statement currently in network 4 looks like you're trying to compare counter.Q to 1, to see if it is true and if so, jump to 'con'. The AND statement examines each input to see if it meets certain conditions, ie true for bool, var=# for byte/word/dword, not comparing the two inputs against each other.
