Hi All,

I have just been asked to help convert S5 STL to ladder but I am having difficulty understanding the branch structure in the STL.

Here is the STL Code. I have just used M0.0 as the address for an example. It is the branch structure I am not sure about. Any help would be appreciated.

A(
O(
A     M      0.0
AN    M      0.0
AN    M      0.0
AN    M      0.0
A(
O     M      0.0
A     M      0.0
)
AN    M      0.0
AN    M      0.0
AN    M      0.0
AN    M      0.0
)
A     M      0.0
AN    M      0.0
AN    M      0.0
AN    M      0.0
A(
O     M      0.0
O     M      0.0
)
AN    M      0.0
AN    M      0.0
AN    M      0.0
AN    M      0.0
O(
A     M      0.0
AN    M      0.0
)
)
AN    M      0.0
=     M      0.0

Hi,

please check the following FAQ - I think it will help you to understand. It contains some examples how STL looks in FBD/LAD.

Why can you not display an STL program in FBD or in LAD?

Hello Professor,

Your network can be converted to LAD and FBD as below:
