OLE for Process Control (OPC)
In this appendix
OLE for Process Control (OPC) provides a standard mechanism for
communicating with numerous data sources. It is immaterial in this case whether
these sources are machines in your factory or a database in your control room.
You can use the OPC server provided with the SIMATIC Computing software to
communicate with the control engine and thus provide access to the process data.
SIMATIC Computing provides an OPC server that allows any OPC client
application to access data in the control engine. SIMATIC Computing does not
provide any OPC client application.
SIMATIC Computing implements the mandatory interfaces, as defined in the OPC
documentation, version 2.0, from the OPC Foundation. SIMATIC Computing also
implements the IOPC BrowseServerAddressSpace interface.
OPC is based on the OLE/COM technology from Microsoft. For more information
about OPC, refer to the OPC specification
OLE for Process Control Data Access
Standard, version 2.0 from the OPC Foundation.
