Overview
Meanwhile, the engineer station can also serves as the normal operator station in real-time monitoring. The server station includes History Data Gather Station, OPC Data Server and Time Synchronization Server. Historical data recording such as trends, alarms and operation records can be performed by a dedicated History Data Gather Station or accomplished by the normal operator station/engineer station as software configured. The recorded historical data will be shared for all the operator station and engineer station over the Process Information Network. As the functionality of historical data recording, can be equipped or configured as redundancy. OPC Data Server is working as an OPC interface, which links Management Information Network and/or third-party system through OPC. By OPC Data Server the system can share the process information with enterprise management system (ERP or MIS), and exchanging data with Application Station (such as APC) or other External Data Source. As the functionality of OPC interface, it also can be performed by a dedicated OPC Data Server or accomplished by the normal operator station/engineer station equipped with OPC package. The various control and automation systems used in the plant shall reference to a common time base to avoid discrepancy in time while comparing data across different system or different operation node within one system. A Time Synchronization Server is used to receive a time synchronization pulse from Global Positioning System and synchronize the time base of all control node and operation node in the WebField ECS-100 system. As the functionality of time synchronization, it also can be performed by a dedicated Time Synchronization Server or accomplished by the normal operator station/engineer station equipped with time synchronization package.

3.2 PROCESS INFORMATION SERVICE AdvanTrol-Pro makes the ECS-100 system implement a process information network with the characteristics of peer to peer C/S on the basis of network strategy and data grouping. Via the process information network, realtime data communication and history data inquiry about realtime data, realtime alarms, history trends, history alarms and operation records can be implemented among operation nodes. 1.
Realtime data service
Server sends data to client: For a data group, the client sends an application for tags to the master server when finding its existence, and the master server sends data to the client at a certain interval; when the client do not need the data, the master server will stop sending them after a certain period time. Client sends data to server (Data write back): client sends data to the master server by using tools such as graphics via process information network. Notes: In the case of a station as client, value-setting action through task is invalid. 2.
Realtime alarming service
For a data group, the master server take the initiative to identify whether there is a client or not and send realtime alarm signals. In addition, the redundant server receives alarm signals from the master server too. An alarm signal involves alarming time and acknowledging time. Signals of realtime alarm acknowledging at master server, redundant server and client is sent via process information network to other master server, redundant server and client for realtime alarm. Realtime alarm whose acknowledging is at local operation node is effective only to the operation node itself. 3.
History trends service
For trends enquiry, if a data group strategy of the station is configured as server-based connection or local connection, then enquiry of trends recorded at the station is available; if the station is client, then enquiry of 3-2
System Software trends recorded by trend master server is available. 4.
History alarm service
For alarm enquiry, if a data group strategy of the station is configured as server-based connection or local connection, then enquiry of alarm recorded at the station is available; if the station is client, then enquiry of alarm recorded by alarm master server is available. 5.
Operation logs service
Operation log is operation node concerned. Operation nodes configured as local connection or server record operation logs generated by the station itself, and operation nodes configured as client send operation logs to master server and redundant server. For enquiry of operation logs, if the station is configured as master (redundant) server or local connection, then enquiry of operation logs recorded at the station is available; if the station is client, then enquiry of operation log recorded by operation log master server is available. 6.
Time synchronization function
The system may receive GPS clock source signal and implements of the time synchronization in the whole control system through SNTP protocol. Otherwise, a time synchronization server can be fixed at the control system, on basis of which implement of the time synchronization.
