61499 compliance confirmations are reported on their website:
as described in (2012) The IEC 61499 Function Block Standard: Software Tools and Runtime Platforms:
In December 2005, ICS Triplex ISaGRAF, a Rockwell Automation company, released version 5 of its wellknown and widely used ISaGRAF Workbench for IEC 611313 programming with support for IEC 61499, thereby becoming the first commercially supported software tool for IEC 61499.
In May 2007, ISaGRAF announced the certification of its IEC 61499 solution compliance by TÜV Süd . The TÜV Compliance Report does not confirm portability of IEC 61499 library elements produced by the ISaGRAF Workbench to or from any software tool other than itself, not does it confirm configurability by the Workbench of any runtime platform other than the ISaGRAF runtime.
Currently, ISaGRAF is shipping Version 6 of its Workbench, built on the Microsoft Visual Studio Shell, which enables value-adding extensions by hardware and machine vendors.
