RSView Supervisory Edition Installation Guide

• the RSLinx data server is installed on a computer separate from the
RSView SE Server. You might want to do this for performance
reasons, or to locate the OPC server physically close to the process.
You can have multiple data servers accessing topics in RSLinx in an
application. Each data server must point at a different instance of
RSLinx.
Next steps If you are using RSLinx for RSView or RSLinx Gateway,
create an OPC topic in RSLinx for RSView, and then create an OPC
data server in RSView Studio that points at the computer on which
RSLinx for RSView is running. For more information, see step 6.
When to use RSLinx Enterprise You must install an RSLinx
Enterprise activation to enable RSLinx Enterprise. Use RSLinx when:
• the information is being provided by a ControlLogix controller.
• alias topic shortcuts are not required.
Communication with third-party local and remote devices
For communications with non-Allen-Bradley local and remote devices,
RSView supports OPC connections. OPC (OLE for process control)
allows RSView to act as a client to other OPC servers.
Next steps Set up the OPC server according to its manufacturer’s
instructions, and then set up an OPC data server in RSView. For more
information, see step 7.
Accessing values in devices
Once an application can communicate with a device, you need to plan
how the application will access the values in the device. To access
values in a device, you can use data server tags, or HMI tags, or a
combination of both.
