For example, the group might represent items in a particular report or operator display. The OPC groups provide a way for clients to organize data. The OPC group object maintains information about itself and provides the mechanism for containing and logically organizing OPC items. The OPC server object maintains information about the server and serves as a container for OPC group objects. Specifics on naming conventions are supplied in a subsequent section.Īt a high level, an OPC server is comprised of several objects: the server, the group, and the item.

Vendor supplied code determines the devices and data to which each server has access, the data names, and the details about how the server physically accesses that data. Different vendors provide OPC servers, and an OPC client can connect to OPC servers provided by one or more vendors. This specification describes the OPC COM objects and their interfaces implemented by OPC servers. Products by OPC members offer a wide range of tools for people who prefer "off-the-shelf" products, to mid-level engineers who like the efficiency of building with a toolkit, to the developer who prefers to build the entire application. OPC standards are based on technologies of the general computing market.

There are now hundreds of OPC Data Access servers and clients.

The COM/DCOM technologies provided the framework for software products to be developed. Originally based on Microsoft's OLE COM and DCOM technologies, the specification defined a standard set of objects, interfaces, and methods for use in process control and manufacturing automation applications to facilitate interoperability. The first OPC standard specification resulted from the collaboration of a number of leading worldwide automation suppliers working in cooperation with Microsoft. Interoperability is assured through the creation and maintenance of non-proprietary open standards specifications. OPC is open connectivity in industrial automation and the enterprise systems that support the industry. Interoperability, open solutions, and freedom of choice have helped automation professionals around the globe realize the advantages of incorporating OPC into their industrial applications.

This is an exciting time in the industry. OPC has helped automation suppliers provide solutions that are truly open, which in turn has given users more choices in their automation applications. OPC has led to improved cooperation between technology providers and users alike. Even when the hardware and software are from different vendors, OPC compliance makes continuous real-time communication possible. An OPC server can communicate data continuously among PLCs on the shop floor, RTUs in the field, HMI stations, and software applications on desktop PCs. OPC is a widely accepted industrial communication standard that enables the exchange of data between multi-vendor devices and control applications without any proprietary restrictions. One application acts as the server providing data, and the other acts as a client using data. There are no stubborn bugs, There are only stubborn Debuggers.OPC Interoperability: Open Connectivity Through Open Standards There is no such thing as the last bug in a program So Theoretically at least if the OPC supports this then it should work. What I understand from this is that the HMI / OPC that you plan to use should support S7-200 Protocol on Ethernet. In "Connections", select the "SIMATIC S7 200" driver. In the TIA portal, you can select the required "Communication driver" with the following menu

Is not in the list, select the "SIMATIC S7 200" driver. In the "Connections table", select the "SIMATIC S7 200 SMART" driver. In the WinCC Flexible software package, you can select the required "Communication driver" – Peer-to-peer (GET/PUT) connections: Eight connections to support S7-200 SMART – PG connections: One programming device (PG) connection. – HMI/OPC connections: Eight dedicated HMI/OPC connections. Ethernet programming port: The CPU provides the following connections:.The CPU supports the following maximum number of simultaneous, asynchronous
Opc server kepware manual#
Here is an Extract from S7-200 Smart Manual : Kepware supports S7 protocols over TCP/IP with many families of s7 PLCs:Ī small paragraph in the catalog suggests that a Siemens OPC server (PC Access) will connect to the S7-200 Smart over TCP/IP I would be enclined to believe that the connection to the Kepware OPC should be established without problem. In the catalog it is mentionned that the S7-200 Smart CPUs have an integrated Ethernet port that supports S7 protocols. Here is a catalog that could help answer your questions: The S7-200 Smart PLCs are a development of the origninal s7-200 CPUs for the Indian market, and there is little information available for us on these units.
