Structured Text Simulator for PLC in Learning Environment
Authors
Abstract
In the current market context, industries need toconstantly remain technically competitive. Such context in which
customers require personalized products force them to design
better products at shorter development cycles. In this regard, the
process control of manufacturing systems greatly influences these
factors. A simulation tool for process automation and control is
proposed, which can simulate a Programmable Logic Controller
(PLC) that can be programmed in Structured Text language,
using multi-tasking. The simulator can be used to verify
dynamical processes and controllers for discrete-event systems,
discrete-time systems, and mixed systems. A description of the
PLC simulation architectures and its development is provided, as
well as illustrative examples.
