Abstract (EN):
During the development of a new parser for the
grammar defined in the latest edition of IEC 61131-3, the authors
came across many inconsistencies between the main body of the
standard and the formal definition of the grammar. This paper
explains the inconsistencies that were uncovered, and suggests
corrections to the formal grammar.
