| OPC Alarm and Event Server
The OPC Alarm and Event Server generates a stream of information, mostly event notifications, and distributes them to the Alarm and Event clients. OPC Alarm and Event 1.02 standard is supported. For more information, see Section 5, Alarm and Event . When running with a third part OPC client in an 800xA, it is important to only connect to the 800xA System OPC interface. Thus you must not connect to the OPC Server for AC 800M. It is only the 800xA System OPC interface that is adequate enough to handle security issues, band width, performances etc in this type of 800xA configurations with a third part client. System Configuration Section 1 Introduction 14 3BSE035983-510 Figure 1. OPC Server configuration in a system. System Configuration The following basic rules apply to system configuration and OPC servers: • One OPC server can receive data or event notifications from multiple control systems, • A maximum of three OPC servers are allowed to subscribe to Data Access and/or Alarm and Event from one controller, • A control system can send data or event notifications to multiple subscribing OPC servers, • Multiple OPC clients can subscribe to data or event notifications from the same OPC server. • A maximum of five third-party OPC clients are allowed to subscribe to Data Access and/or Alarm and Event from one OPC server, Controller OPC Server for AC 800M Control Builder Controller Ethernet Controller OPC Client MMS server COM/DCOM MMS Section 1 Introduction Network Considerations 3BSE035983-510 15 • A maximum of four Ethernet links (two redundant) are supported via Ethernet cards. • A third-party OPC client should, if possible, be installed on the same PC as the OPC server. Otherwise, there is a potential risk that communication will not restart after a communication failure (only for CCB Users). For details regarding the maximum number of supported controllers from which the OPC server subscribes data, refer to Compact Control Builder AC 800M Product Guide (3BSE041586*). tải về 0.83 Mb.
