Hello,

Please, follow our previous discussion in the following link, in general STL is low level programming and it provides all instructions that are necessary for almost all complex tasks with some programming labour.While in SCL, tasks can be implemented with less troubles and it is easier(compared to STL)if programmer is familar to high level programming.

Selection of proper programming Language

difference LAD STL SCL ?

Normally, programs based on graphical representation of logics is ideal for people who are familiar with logical gates (FBD) and others who know relay-contactor control circuits(LAD).These are options that are available for almost all popular PLCs from different manufacturers based on what forced by international standards.

All other graphical languages can be converted to equivalent STL codes, a language close to machine level, but generally all STL codes can not be converted to graphical equivalent.The most important advantage of using STL compare to its graphical counterparts would be ease and speed of development and development of a complex logic in one network(there is aslo a line number limitation for that).When you want to run a timer in STL,you skip all unnecessary parts and just ,concisely, write the important sections.There are also some limitations with graphical languages like indirect addressing and cumbesome implementation of complex logics in LAD(FBD).

Finally, SCL is the high level programming langauge.It is like PASCAL and ,ideally speaking, can help us to implement any possible complex loop,data management and computational algorithms.Despite the fact that SCL is not efficient with conversion instructions but overally, it offers flexible options for experienced programmers(or even starters).
