  This paper introduces the concept of plant model generation from the recorded
traces of events using the process mining technique. The event logs are
obtained by visually simulating a simple distributed manufacturing system using
the OPC UA communication protocol. The process discovery alpha algorithm is
used to extract the process model in Petri net format. The system behavior
represented in terms of Petri net is then fed to construct the ECC of the basic
function block in compliance with IEC 61499 standard using the proposed
notation. Finally, the formal verification of the closed-loop system is done
with the help of a tool chain that consists of fb2smv converter, symbolic model
checker NuSMV, and other tools for representing counter-examples.
