“…It also involves IEDs at the Bay level responsible for receiving and sending data and control from/to HMIs and other IEDs in the Process bus. Communication between IEDs is carried out through Generic Object Oriented Substation Events (GOOSE) messages while communication between an IED and an HMI is carried out via MMS [12] messages. The Process level involves Merging Units (MUs) responsible for digitizing analog data (e.g., voltage, current) from primary equipment (e.g., current transformers, potential transformer) and sending Sampled Values (SVs) to IEDs.…”

“…The interoperability of industrial devices is thus of crucial importance. Communication interoperability is achieved by means of a specific standard at the Application Layer, the ISO 9506 Manufacturing Message Specification (MMS) [3], [4]. The MMS standard provides a common communication platform for different types of devices, by means of abstract models which defme their externally perceived characteristics and behavior.…”

The great diversity of the devices that need to be interconnected in the industrial environment creates the need for interoperability. Communication interoperability is dealt with by using the Manufacturing Message Specification ISO 9506 standard in the Application Layer of industrial networks, which provides an abstract representation of the external characteristics of real manufacturing devices. In addition to the communication interoperability, the need for device interoperability has led to the defmition of the User Layer: an eighth layer in the OSI-RM for fieldbuses. The ISA/IEC 5P50 emerging standard on fieldbuses defmes the characteristics ofthe User Layer functionality and the required objects. This paper presents an integrated solution for problems associated with industrial communications and control being developed at the University of Patras, Greece. Specific object oriented tools are being developed for the User Layer. The Function Block Builder tool allows the defmition and creation of Function Block objects according to the emerging fieldbus standard. The Graphical Editing tool provides an integrated environment for the creation of Logical Node objects by means of interconnecting Function Block objects. The above tools are part of an integrated environment consisting of the Application Layer (MMS) and the Network Management software. Furthermore, the Graphical Editing tool provides the capability of mn-time monitoring as well as of dynamic reconfiguration of the industrial application. Finally, the complete system has been installed in industrial test-bed applications.

This paper deals with the definition of a device description model which takes into accountthe most significant features of the fieldbus devices currently available on the market and included in the EN501 70 European standard. The basic concepts that can be found in the relevant international standards have been taken as a basis for the development of the model. The model is formally described in Express since it is a well assessed data modeling language for which a graphical subset also exists. Several tools for processing Express models are widely available nowadays on different platforms. Hence, the model can be translated into a corresponding representation for a specific host language with relatively little effort. The basic aim is that of providing a common understanding of the device features through the structured organization of data, parameters, event and actions so that interoperability is guaranteed independently of the specific fieldbus technology used in the network. Each device is described using the entity -relationship approach and takes advantage of the inheritance property which leads to a simple and immediate description of new device features which can be added to the hierarchy without affecting the existing structure of the model. As an example the paper also shows how the proposed general model can be refined to describe a particular class of real devices including more specific attributes and events.
