LAD to SCL

H P Posts: 18 Rating: (0)	Hello, I need to convert a few Ladder circuits to SCL. In one of the LAD, there is a timer defined which is being used in another LAD. How can I convert it to SCL. I am attaching a very basic version, comprising of 2 networks, as an example. Thank you. H Attachment LADtoSCL.zip (755 Downloads)

SCL is a much higher level language than LAD, so the system will not do it for you. The only way is to do in manually, which will be quite difficult and time consuming. In STL it would be no issue, as you can view code written in any language as STL.
