Abstract (EN):
The IEC 61508 standard recognizes the
programming languages defined in IEC 61131-3 as
being appropriate for safety-related applications, and
suggests the use of static data type analysis of the
source code. In this context, we have added a data type
semantic verifier to the MatIEC compiler - an open
source ST, IL and SFC code translator to ANSI C. In
so doing, we have identified several issues related to
the definition of the semantics of the IL and ST
programming languages, as well as with the data type
model defined in IEC 61131-3.
In this paper we describe the issues we uncovered,
explain how the data type static analyzer of the
MatIEC was implemented, explain the options we took,
and suggest how the IEC 61131-3 standard could be
made more explicit.
