Abstract: To indroduce the international standard IEC 61131-3 briefly and discuss the
essentiality, feasibility, superiority and deficiency of applying the standard IEC 61131-3
Especially, to discuss the capability of gradual migration from existing PLC applications to
IEC 61131-3-compliant programs. Giving the examples of automation project , the
plans and practices for modularization and repetitional production of PLC applications
are introduced.
