Abstract-The second edition of the IEC 61499 standard aims to clarify the interpretation ambiguities of function block's execution semantics. This resolves the pivotal issue of realizing portable and interoperable implementations of the IEC 61499 reference architecture. As the IEC 61499 standard is about entering its technology takeoff phase, these clarifications are timely and important. It is hence expected that more innovators of automation software tools, runtime environments, and control hardware will start adopting this technology. To assist such adoption, this paper presents a study of existing IEC 61499 tools' portability issues. In particular, the features of currently active IEC 61499 tools, such as FBDK, ISaGRAF, 4DIAC, and nxtStudio are outlined. Their incompatibility issues due to different execution semantics are exemplified. Moreover, it is also illustrated in this paper how these issues can be addressed by complying with the updated norms.

“…This is the reason, according to [1], for the appearance of several proposals for the execution of IEC 61499 based applications. The synchronous model of execution [2], the cyclic model of execution [25] (see [1,25]), and the ISaGRAF model [20], which is considered close to the cyclic model, are given as examples of this kind of implementation, that is characterized as a cyclic execution model. Moreover, it is claimed that "these models "bend" a bit the fundamental concepts of eventdriven invocation, implemented in the pure event-driven implementations, such as FBRT and FORTE. "…”

“…Moreover, FBRT is not based on the event-driven paradigm, since it implements the event connections between FB instances, as method invocations, and this is why, as also claimed in [20], it cannot be regarded as a reference implementation. Example implementations based on the event-driven paradigm are described in [24,26].…”

The industrial and research activities around the IEC 61499 architecture for distributed automation systems are discussed by Vyatkin, (2011). Research results related to the design of this kind of systems as well as to the execution of IEC 61449 on embedded devices are reviewed. It is claimed that IEC 61499 has been developed to enable intelligent automation through the distribution of software components and that the industry will benefit through its adoption from the promise of the intelligence automation research results. In this paper, several observations are presented on the arguments that are used to prove that IEC 61499 is a solid technology for industrial automation systems development. Portability, interoperability, code modularity, reusability, and reconfigurability as well as determinism and the event-driven execution of IEC 61499 are discussed.

IEC 61499 is a standard architecture, based on function blocks, for developing distributed control and measurement applications. However, the standard has no formal semantics and different interpretations of the standard have emerged. As a consequence, the execution behavior of applications running on different platforms may exhibit different behavior, thus making it harder to transfer applications between the platforms. This paper shows how three different execution semantics, buffered sequential execution model (BSEM), nonpreempted multithreaded (NPMTR), and cyclic buffered execution model (CBEM) can be mathematically defined. The mathematical definitions can be used to analyze an application's behavior when executed using those execution semantics. The mathematical definitions have been used as a basis for implementation of a runtime environment and a software tool that generates formal models suitable for formal verification. Formal verification can be used to help discover execution errors before the application is executed on the factory floor.
