The IEC 61499 architecture is a new standard proposed to replace current PLC technologies. This paper aims to develop a guide to migrate from IEC 61131 PLC technologies to IEC 61499 function blocks, especially for PLC programmers. Multiple PLC platforms are chosen as examples and transformed function block system is provided. Beyond migration rules, current limitation and cautions during migration are discussed on the final section of this paper.
