different OPC servers. Instead, select the new server and add the data points

you want to include.

Generic OPC Data Points

The Generic OPC control connector service is an OPC client and

communicates with an OPC server according to the OPC standards. The

OPC Data Points dialog box allows you to browse a list of the servers

supported by the Generic OPC control connector. If the OPC server supports

tag browsing, then you can browse for the desired OPC items to create data

points. The Generic OPC control connector has full DCOM support, which

allows an OPC server to reside on a remote PC if the DCOM security is set

correctly.

RSView32 Data Points

RSView32 6.10.16 or higher supports transmitting data via OPC. In

RSView32 6.10.16 through 6.3x.xx, an OPC browse was not enabled.

Therefore, if you are using those versions of RSView32, you must use the

FactoryTalk Transaction Manager RSView32 connector to provide the

browsing capability. If you are using RSView32 6.40.00 or later, you can

use the FactoryTalk Live Data connector (recommended), RSView32

connector, or the Generic OPC connector.

To connect to data points from a RSView32 connector when the project is

not on the FactoryTalk Transaction Manager user interface computer,

RSView32 needs to be installed locally to provide the correct registry keys

to allow remote browsing. (The same is true if using RSView32 6.40.00 or

later and using the OPC connector). In the RSView32 project, use the

RTDataServerOn command to turn on the data server and allow FactoryTalk

Transaction Manager to read RSView32 tags. To provide write access to

RSView32 tags, you must issue the RTDataWriteEnable command.
