Different causes have contributed to the shift of
paradigm in the automation field from centralized to modular
and distributable. Software and hardware of Programmable
Logic Controllers (PLCs) have evolved to be synchronized with
the demands nowadays and new standards are trying to follow
this trend. One of them is the IEC 61499 standard, which is
intended for modelling distributed industrial solutions with a
vendor-independent format. This shifting is also bringing new
challenges and this paper focuses on the virtual commissioning
of plants, which can become a harder task when the system
is distributed and involves different interconnected modules.
A major problem when doing a virtual commissioning is the
coupling between the different physical systems and controlling
tools since many vendors still offer closed integrated solutions.
Functional Mockup Interface (FMI) is a standard for a cosimulation
interface which intends to fill the gaps between
different modelling tools, by packaging the models into Functional
Mockup Unit (FMU) and allowing a co-simulation master
algorithm to have access to the inside model through the proposed
interface. This paper presents a mapping between IEC 61499
models and the FMI standard and an implementation of a tool
that can export IEC 61499 models into FMUs, which would allow
the co-simulation of physical plants and the PLCs software that
controls it. An experiment is shown where a simple ProportionalIntegral-Derivative
(PID) controller of a tank system is exported
as an FMU and co-simulated together with a tank system
modelled using OpenModelica.
