18. Integrate OPC Client and use steps
18.1 Overview

OPC is a protocol that has a C/S structure and is widely used in the industrial field. It briefly introduces the basic situation of OPC in "16. Integrated OPC Server and usage steps. Generally, the OPC Server provides external interfaces for reading data. For example, the device driver of ServerSuperIO can directly write the measured point data to the OPC Server. The OPC Client actively connects to the OPC Server, and read the data information of the server through synchronous, asynchronous, and data change events. OPC Server and OPC Client are many-to-many relationships. OPC Server can provide data sources for multiple OPC clients, and OPC Client can also read data information from multiple OPC servers.

As one way to collect data information, the OPC Client integrates ServerSuperIO with this service. It exists as a service and is different from the hardware data collection method by the device driver. The integration of the OPC Client service only involves the use process and does not involve code development. You only need to configure it to directly Save the read data to the real-time database.

18.2 ServerSuperIO OPC Client use process 18.2.1 OPC server test tool and create measurement points

You can find the OPC Server test tool in the "OPC tool and component \ OPC Server test tool" Directory of ServerSuperIO v3.5. Open the tool to create OPC measurement points and dynamically generate data. For example:

 

18.2.2 use the configuration tool to configure basic information and read measurement points

You need to set the content of the basic configuration menu. The main parameters include: (1) Name of the table written to the real-time database. You can enter an existing table name. (2) set the Data Reading interval, which is applicable to synchronous and asynchronous data reading. (3) set the Data Reading method. When the server data changes, the system automatically triggers the Data Reading event, synchronous data reading, and Asynchronous Data Reading. (4) set whether to save the read data to the real-time database. If you need to save the data, set the configuration information of the real-time database correctly. (5) Whether to enable the OPC Client service. If it is enabled, the host Program Based on ServerSuperIO will have this service, and the secondary development kit will also have this project service.

 

Open the OPC Client configuration menu, read the measurement point data provided by OPC Server according to the hierarchical relationship of service, group, and tag, and save the current configuration information, after the ServerSuperIO main program is started, the data information is automatically read. For example:

Main Program

Real-Time Database

18.3 precautions

If the measurement point created on the OPC Server is named "Random. tag1, then the name saved to the real-time database is changed to "RandomTag1", and ". "removed, mainly considering the compatibility between components.

18.4 application expansion

OPC Client is an independent service component. How can an independent service component be integrated with ServerSuperIO? The framework provides the ServerSuperIO. Service. IService Service interface, and integrates the OPC Client component into the entity class of the IService interface. The ServerSuperIO framework automatically instantiates the IService interface object.

Similar to other services, such as reading data from other data sources, analog output, and LED Display output. The IService interface is defined as follows:

Public interface IService: IServiceConnector, IPlugin {// <summary> // service Key, which must be unique // </summary> string ServiceKey {get ;} /// <summary> /// service name // </summary> string ServiceName {get ;}......}
