Software 3 OPC data server software OPC Factory Server

Transcription

1 Presentation Presentation Based on the OLE for Process Control (OPC) standard, Schneider Electric's OPC Factory Server (OFS) software allows client software s, such as supervisors/scada and customized interfaces, to access the data of Schneider Electric automation system and electrical distribution devices connected to networks or fieldbuses in real-time. It also allows communication with third-party devices supporting Modbus and Modbus/TCP protocols. At the heart of the Transparent Ready offer, OFS enables simpler, more open and transparent communication between your software s and your devices. These are just some of the advantages that ensure a complete interoperability solution that is central to your process. In version V., the OFS data server integrates the most recent specifications of the OPC Foundation: b OPC-DA (OPC Data Access) b.net API interface b OPC XML-DA V.0 (OPC XML Data Access) The OFS V. offer is available in two levels: b OFS Small: Data server for 000 items () that does not support the OPC XML-DA protocol b OFS Large: Complete data server Devices and protocols supported OFS software is a multi-device data server: it allows simultaneous use of several communication protocols, and it provides client s with a set of services for accessing control system items that may be local or remote, via physical address or via symbol. Devices supported: b Modicon Quantum, Premium, Micro, Compact and Momentum PLCs b TSX Series and April Series 000 Schneider Electric PLCs b Modbus Serial devices connected via Schneider Electric gateways: TSX ETG 0pp, EGX ppp ranges, etc. b Uni-Telway serial devices connected via Schneider Electric gateways (TSX ETG 00) Networks and protocols supported: b Modbus: Modbus Serial, Modbus Plus, Modbus/TCP b X-Way/Uni-TE: Uni-Telway, Fipway, ISAway, PCIway Openness The development of specialized interfaces is simpler with OFS V. software, which is aimed at two types of user in particular: b End users who want either to interface their supervision or Human Machine Interface s with Schneider Electric equipment, or to develop s on a PC (supervisory control screens, Excel tables, etc.) requiring access to control system data. b Suppliers of automation system or industrial data processing software (supervision, Human Machine Interfaces, etc.) seeking to develop, within their standard products, an OPC Client interface capable of accessing data in Schneider Electric equipment via the OFS server.

2 Presentation (continued) 0 Supported architectures The OFS server allows four access modes: b A purely local mode b Remote access from an OPC-DA client b Remote access from an OPC.NET client b Remote access from an OPC XML-DA client Local access The client and the OFS server are on the same PC.

3 Presentation (continued) 0 Supported architectures (continued) Remote access from an OPC.NET client The.NET client and the OFS data server are on remote stations. Communication between the client station and the OFS server is conducted through the DCOM layer (Microsoft) via the OPC-DA protocol. DCOM Intranet Ethernet Modbus/TCP network.net client Server OFS station The.NET Microsoft compatibility of the OFS server has been developed to allow an OPC.NET client to access OFS server items on an Intranet network via the OPC.NET API interface. This interface ensures interoperability between existing OPC s and s developed in the standard.net environment. Remote access from an OPC XML-DA client via HTTP The client and the OFS server are on remote stations, using the SOAP protocol to communicate via the Internet in conformity with the OPC XML-DA V.0 specification of the OPC Foundation. The OFS data server is based on an HTTP server installed on the same station. Symbol data (Unity Pro, Concept or PL) Site server and OFS station Internet Industrial network IIS Firewall Remote client Industrial PLCs The OPC XML-DA V.0 specifications are designed to overcome the limitations of COM/DCOM by providing: b An OPC interface for Windows and non-windows client s b Beyond the Intranet perimeter, remote access via the Internet through firewalls The OPC XML-DA specification is based on Web Services standards such as SOAP, XML and WSDL (). A SOAP client can access data on the OFS server via Intranet or Internet using the SOAP protocol in conformity with the OPC XML-DA V.0 specification of the OPC Foundation. 0 () SOAP: Simple Object Access Protocol XML: Extensible Markup Language WSDL: Web Services Description Language page / / page / page /

4 Setup Setup Ethernet Modbus/TCP OPC client Quantum OFS server (V.0) Database Symbols.xvm (Unity Pro) Symbols.prj (Concept) Symbols.scy (PL) Unity Pro project station Ethernet Modbus/TCP Premium Momentum TSX Micro The OFS server is the centre of data exchanges. The direct dynamic link between the OFS server and the Unity Pro project station results in productivity gains for designers and users of the devices. OFS has direct access to the items in the Unity Pro project. In addition, it performs a consistency check between these items and those of the Premium and Quantum PLCs. Note: Depending on the software used for setting up Modicon PLCs: - PL software generates PLC variables symbols export files. These export files (symbols.scy) must be integrated in the OPC server. - Concept: The variables can be accessed directly in the project (file.prj) of the Concept. This direct link requires Concept (version.0 or later) to be installed on the OFS station. - If the Unity Pro project development station is not accessible via the OFS station, the PLC variables symbols export files (symbols.xvm) generated by Unity Pro must be integrated into the OPC server. 0 Presentation: page / page / page / /

5 Functions Functions Development of client s OFS software has types of interface: b OLE Automation interface (OPC-DA) Particularly suitable for end users, this enables the development of OPC client s in Visual Basic, in Visual Basic for Excel, and in C++. b OLE Custom interface (OPC-DA) Used primarily by suppliers of automated control system or industrial IT products, it enables the development of s in C++ in order to access the OFS software OPC server. This interface is particularly aimed at software development experts, so that they can integrate the client into their standard products. This is the interface offering fastest times for accessing data stored in the OPC server. It requires extensive knowledge of C++ ming to set up. b OPC.NET API wrapper interface The.NET Microsoft compatibility of the OFS data server gives an OPC.NET client standard access to OFS server items via an Intranet network, thus ensuring greater interoperability with standard.net environments. Note: In this case, communication between the OPC.NET client and the OFS server is conducted through the DCOM layer (or COM layer in a local configuration) via the OPC-DA protocol. b OPC XML-DA interface () The OPC XML-DA V.0 specifications are designed to overcome the limitations of the OPC-DA specification and COM/DCOM by providing: v An interface for Windows and non-windows client s v Remote access via the Internet through firewalls (beyond the Intranet perimeter) The OPC XML-DA specification is based on Web Services standards such as SOAP, XML and WSDL. A SOAP client can access data on the OFS server via Intranet or Internet using the SOAP protocol in conformity with the OPC XML-DA V.0 specification of the OPC Foundation.
