Abstract (EN):
Modern industrial environment control programs
are distributed among several devices. The IEC 61499 standard
defines function blocks with which distributed control applications
may be developed, and how these are interpreted and executed. Its
functionality and the inherent support for dynamic
reconfiguration provide the required infrastructure for Industry
4.0 and industrial IoT applications. However, by their distributed
nature new challenges are posed, especially about how modes of
failure are handled. To avoid system malfunctions and
breakdowns due to partial failures, the authors propose a new
framework were the concept of replication can be applied
maintaining internal state synchronised. This paper presents an
example of how the replication framework on the FORTE IEC
6499 execution platform can be developed and voting strategies,
along with the results obtained in the implementation with the
standard communication SIFBs available on the Eclipse 4diacTM.
