STL Network In Ladder Block

I have a program that has some blocks, written mostly in ladder, that have some networks programmed in STL. So some blocks have a mix of ladder and STL in the same block. How is this done?

I have a new block I'm programming and it's in ladder, but I would like to insert a network in STL in this block. But every way I can see to insert a new network will insert it in ladder.

Here is an easy options for adding STL Code in a LAD Block.

In your LAD Block , switch to STL , add new network, add STL Code, then switch back to LAD

 If I switch to STL, add a network programmed in STL, and switch back to LAD, would it not switch the new network to LAD as well assuming the STL instructions I used are able to convert to LAD? Is the implication that the only networks that will display in a LAD function are networks using STL instructions that are not able to convert to LAD? Is there any way to force a single network to display in STL while the rest are in LAD, even if the STL could be converted to LAD?

TIA or Classic Step7?

 I use both, Step 7 V5.5, TIA V13,14,15,15.1 etc

 In TIA, you can add a STL/SCL network to a  FC/FB.made with LAD, and you will see it always as STL/SCL.

 Thank you, yes I see this option in TIA. How is it done in Step 7?

 Thank you, yes I see this option in TIA. How is it done in Step 7?

 Please be careful. You have Step7 Classic and Step7, TIA Portal. Unfortunately both are called "Step7". But your question is about Step7 V5.x

In Step7 V5.x:
STL will convert to LAD if it can do so, when changing language from STL to LAD. It is however very easy to make an STL network which cannot go to LAD. The code we prefer to use STL does not have LAD equivalent circuits most of the time.

What I have done in the past is to create a STL network that only contains the line

NOP 0

 I used this line to copy/paste where I wanted to have a network with STL. It could even be something like having complicated commentary. So just the NOP with comment lines!

You can leave the NOP (no operation) there and add STL code. But I am sure you will very quickly see which codes do not need the NOP line anymore.

Does this help you?
