Which IEC 61131-3 programming language is best?

LD remains a great language for which it was originally intended – complex Boolean logic. Staying within this realm, LD logic is simple to design and simple to debug. Figure 3 illustrates this point by showing the same Boolean logic in several IEC 61131-3 languages. Say we are expecting “Inspect” to be TRUE.

How many PLC languages are officially part of IEC 61131-3?
