Hello Mahesh; I feel that your last statement is a rash conclusion. Umencho's answer was a response to your first question, which was based on a misunderstanding of OPC standards. OPC is based on a client/server architecture. An OPC server cannot read/write to an OPC client or an OPC server. Only an OPC client can ask an OPC server for information (read/write). An OPC server can only reply to a request from an OPC client. See the following information from Matrikon, a well-known developper of OPC clients and servers: http://www.matrikonopc.com/resources/opc-server.aspx An OPC Server will respond to requests, and provide data to one or more OPC Clients in a standard, consistent manner. Any compliant OPC Client can interface with, and request data from any compliant OPC Server, regardless of the vendor, or the underlying system providing the data. Please review your initial post, and try to re-write it in terms of OPC basics. Then maybe we can discuss if OPC is a useful standard in automation projects. Hope this helps, Daniel Chartier |
