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(More)

A library for parallel IO and data management has been developed for large-scale multi-physics simulations. The goal of the library is to provide sustainable, interoperable, efficient, scalable, and convenient tools for parallel IO and data management for high-level data structures in applications, and to provide tools for the connection between(More)

A library called HIO has been developed for large-scale multi-physics simulations, based on the UDM library [10]. The goal of the library is to provide sustainable, interoperable, efficient, scalable, and convenient tools for parallel IO and data management for high-level data structures in applications, and to provide tools for the connection between(More)
