Sharing tag values locally
RSView32 works as both an OPC or DDE server and an OPC or
DDE client. This means you can share tag values with a wide range of
devices and other Windows applications.
4.
The rest of this chapter explains how to use OPC and DDE to
exchange values between different applications on the same computer
(that is, locally). For exchanging tag values between multiple RSView32
computers over a network, OPC is the recommended method. For
details on exchanging values over a network, see “Using OPC for
peer–to–peer network communications” on page 17-5.
Providing tag values to local OPC or DDE clients
When Windows applications request tag values from RSView32, the
requesting applications are OPC or DDE clients and the RSView32
project providing the tag values is an OPC or DDE server.
Enabling RSView32 as a server
To enable RSView32 as a server, do one of the following:
select the OPC/DDE Server check box on the Startup page of the
Startup editor and run the project
issue the RTDataServerOn command (from the command line or
another RSView32 component)
Setting up a local OPC client application
To use OPC, the OPC server must be registered on the computer. The
Node editor lists OPC servers that are registered on the computer
(click the Browse button next to the Server Name field).
