Siemens S7 Serial OPC Server




Overview

Siemens MPI/PPI OPC Server 320 was developed by OPCTechs Technology Corporation. According to the standard OPC 3.0 Specification, we developed the packaged software for our extended customers especially in the automation fields. It is suitable in the integration fields in every walk of life. MPI/PPI protocols are a standard communication protocol of Siemens Corp. OPCTechs Siemens OPC Server could connect with all S7 series of Siemems PLC by serial communication.

OPC Compliance

Compliance Testing is a process which verifies that an OPC product implements a specification properly by using a standard software test tool developed by the OPC Foundation. This test tool, called the Compliance Test Tool or CTT, is currently available for several specifications. Vendors can download the CTT from the OPC Foundation website and run the tests at their site. The company’s administrator or designated product manager for the OPC Foundation WEB site can then attach the encrypted file generated by the CTT to the appropriate OPC Foundation Product catalog item. The OPC Foundation Product Catalog will display the results to the public. OPC Users should look for OPC Server products that have passed the compliance tests for all specifications that the product supports and display the “Self Tested” logo.Compliance Testing is only available for OPC Server products.

Integration Different Kinds of PLC

Project Introduction:

Generally, MIS department exists in well-established company to collect instrument operating data to analyze the data and give report, also, of course to write PC program. Data collection is always an annoying trouble for most MIS engineers because all the programs are designed with different programming languages. Now, with the help of OPC Server, all the problems mentioned above can be solved easily rising the efficiency. OPCTechs Technology Corp. provides OPC Server for most popular PLC. Programs written by different programming languages could also communicate through Data Exchange OPC Server.



System Requirement:

  • VB programming language

  • VB.NET programming language

  • OPCTechs Panasonic Serial OPC Server

  • OPCTechs DataExchange OPC Server

  • OPCTechs Yokogawa Serial OPC Server
  • OPCTechs Yokogawa Ethernet OPC Server

  • OPCTechs Koyo Serial OPC Server

  • OPCTechs Fuji Serial OPC Server

  • N-Port

    Conclusions:

    OPCTechs OPC Server support part of popular devices, such as all series of Melsec PLC, Omron PLC and AB PLC. Moreover, we also provide well organized structure of OPC Server and Client, so all the monitoring program and self-developed program could be integrated with each other easily. Time for developing Driver program could be saved.
