Greetings,

You can add a Jump command, via Right Click and add "Jump" function. After that you have to specify "Label Name".

Each network has a label that can optionally be left empty. This label is edited by clicking the first line of the network, directly next to the network number. Now you can enter a label, followed by a colon.

Please see attach picture for details.

Hope it helps you.

thanks titus... for the support. I really appreciate it. By the way, do you have to do the return after each jump?? how does this work? could you please elaborate this a little bit. Found no manuals on this. thanks

It would be so nice if you could pass on the manual for control builder plus programming " codesys technically"...

Titus, when i turn on "val1 & Val2" ---"Value" will be deactivated. when i turn off Va1 and val2, "value will" be activated. But when i turned back "val1 and Val2" ON, the value remains activated. Shouldn't it be deactivated?? it should skip that rung, right? Could you please shed light on this one...

Thanks Titus

Rung No.2 will be skipped during Jump condition and its output status will remain in the previous state.

hi govinda thanks for the comment. Also, how do we end the block unconditionally?

here is the code that i want to have on the last rung (at the end), copied from s7 rung. Do we need to do that on codesys after each jump instruction?

run: A M 1.5
L DW#16#FFFFFFFF
T MD 64
tstn: BEU

"BEU = BLOCK END UNCONDITIONAL" IN s7 IS COMPARED TO WHAT IN codesys?

Jump will be used to skip execution of some instructions/rungs based on condition. Iam not sure, what your requirement is about in the above example. Generally RETURN will be used in subroutine (to leave the POU and return to call function)
