IEC 61131 on IEC 61850 platform *

IEC 61131 / 61499 is regarded as the first vendor independent standardized programming language for industrial automation, and is being used in a variety of applications which requires advanced logic computations. IEC 61131 is quite popular in Europe, as well as in North America and Asia.

IEC 61131 defines the same for centralized I/O based architecture while IEC 61499 is a related standard which caters to decentralized & distributed communication based architecture.

IEC 61131 and its sub-section IEC 61131-3, reduces the development lead time of systems that are today increasingly centered around complex softwares for control and automation. Being vendor independent, IEC 61131-3 supports multiple languages within a control program. Moreover, the programming is completely independent of the hardware platform, thus providing a greater degree of flexibility and reusability, as well as better pricing and reduced maintenance costs.
