IEC 61131-3 is the third part (of 10) of the open international standard IEC 61131 for programmable logic controllers, and was first published in December 1993 by the IEC. The current (third) edition was published in February 2013. Part 3 of IEC 61131 deals with basic software architecture and programming languages of the control program within Learn from PLC Programming Examples. Another reason to make use of ladder logic examples is, that you can learn from them. Let’s say you have a specific functionality, you want to implement in your ladder logic, a PLC timer function for example. ST has been designed to work with the other PLC programming languages.
