This function only applies to FactoryTalk Live Data and OPC data servers. If you are
using a DDE data server, a Good value is always returned.
OPC Data Points
OPC data points are used by the RSLinx Classic OPC, Generic OPC, and
RSView32 connectors, but can also be used by FactoryTalk Live Data
connectors.
―The OPC Specification is a non-proprietary technical specification that
defines a set of standard interfaces based upon Microsoft’s OLE/COM
technology. The application of the OPC standard interface makes possible
interoperability between automation/control applications, field
systems/devices and business/office applications.‖ For further information,
visit the OPC Foundation’s web site at www.opcfoundation.org.
RSLinx Classic OPC Data Points
RSLinx Classic must run as a service (not as an application) on the computer
that is running the RSLinx Classic OPC control connector. When
FactoryTalk Transaction Manager uses OPC to communicate with RSLinx
Classic, RSLinx Classic 2.52.00 is recommended.
On the RSLinx Classic OPC Data Point dialog box, data points are sorted by
the associated connector, server, and host server. If you select a different
OPC server, only the data points with that server display; this also applies
when you select a new server or connector. You should not create a new
RSLinx Classic OPC control connector to collect data from data points in
