IEC 61131-3 and IEC 61499 in action

The standard IEC 61499 (Functionblocks) is implemented on several platforms. NXTControl demonstrates a couple of PLCs (from Beckhoff, Siemens, ...) with IEC 61499 at the SPS/IPC/DRIVES Fair in Nuremberg (Germany) this week. 

After discussions with several experts I expect a big move towards more standards in the Automation arena. The financial crisis lets more people think about using well accepted international standards - to get rid of too many vendor specific or even standardized solutions.

IEC 61499 focuses on:

Portability: the ability of software tools to accept and correctly interpret library elements produced by other software tools.

Configurability: the ability of devices and their software components to be configured (selected, assigned locations, interconnected and parameterized) by multiple software tools.

Interoperability: the ability of devices from different vendors operating together to perform the functions specified by one or more distributed applications.

The interoperability is mainly provided by a standardized international information and information exchange standard like IEC 61850. Several people I met at the fair yesterday are looking for the combination of the two standards: IEC 61499 and IEC 61850. More to come soon.
