Abstract: |
Proposed in this paper is the
architecture of a PLC programming environment that enables a visual
verification of PLC programs. The proposed architecture integrates a PLC
program with a corresponding plant model, so that users can intuitively
verify the PLC program in a 3D graphic environment. The plant model includes
all manufacturing devices of a production system as well as corresponding
device programs to perform their tasks in the production system, and a PLC
program contains the control logic for the plant model. For the
implementation of the proposed PLC programming environment, it is essential
to develop an efficient methodology to construct a virtual device model as
well as a virtual plant model. The proposed PLC programming environment
provides an efficient construction method for a plant model based on the DEVS
(Discrete Event Systems Specifications) formalism, which supports the
specification of discrete event models in a hierarchical, modular manner. |
