Driver Manual (Supplement to the FieldServer Instruction Manual) FS-8707-06 FST OPC Server for FieldServer APPLICABILITY & EFFECTIVITY Effective for all systems manufactured after February 2012 A Sierra Monitor Company Driver Version: 1.01 Document Revision:...
Access (DAA). The Data Arrays are arrays of typed data memory in the FieldServer. The source of the information in the Data Arrays can be any one of the standard FieldServer I/O Drivers. It is incumbent on the user to configure the ports and the Map Descriptors on the FieldServer.
Before proceeding to configure the OPC Server it is important to have a proper TCP/IP network setup - verify this by PINGing a FieldServer. Refer to the Microsoft documentation for the setup of the TCP/IP networking on the PC. FieldServer Part #...
This Nx connection must be used to connect to the OPC Server machine. Open a DOS box and “PING” the FieldServer from this machine to confirm that the networking is correctly setup. Take note of the IP address.
FS-8707-06 FST OPC Server for FieldServer CONFIGURING THE OPC CLIENT TO USE THE FST OPC SERVER The OPC Client refers to the application using the data available in the FieldServer. Normally this is a SCADA system or other third party software.
This Nx connection must be used to connect to the OPC Server machine. Open a DOS box and “PING” the FieldServer from this machine to confirm that the networking is correctly setup. Take note of the IP address.
Primary Rate The rate at which the OPC Server will poll the FieldServer The rate at which the OPC Server will poll the FieldServer after the access time is expired. If Secondary Rate the access time is less than the primary poll rate, the secondary rate will be used.
Appendix A.1. Locating the “FieldServer.7.16.x” file When Configuring an OPC Client link to the FieldServer OPC, the OPC Client will be browsing for available Servers using the OPC Foundation supplied utility OPCENUM.EXE (Installed with the FST OPC Server for FieldServers) Appendix A.1.1.
Appendix A.5. Fix IO User account The FieldServer OPC server needs to be running continuously if it is being used in an OPC Client application. Since the OPC Server was created off the Intellution Fix OPC system, it is possible to set it up as a Windows Servicethat runs continuously in the background.
The FieldServer limits the speed to about 50 poll blocks/sec (to test set poll rate to 0). e.g.. with 2 FieldServers the total poll rate is ~100/s, if there are 10000 digitals in one Data Array on each FieldServer that translates to 2*50*10000 = 1 000 000 digitals per second.
