RSLinx Classic Gateway
Quick start
Step 1 Configure a driver
Chapter 1 Welcome to RSLinx Classic
• V4.20 adds an RSLinx Classic Local OPC service to permit 64-bit clients
to access the OPC DA interface from the same workstation.
RSLinx Classic Gateway extends RSLinx Classic-based communication
throughout the enterprise by connecting clients over TCP/IP networks.
Programming and configuration products such as RSLogix and RSNetWorx
use a local RSLinx Classic Lite or better with a Remote Devices via Linx
Gateway driver configured to communicate to the RSLinx Classic Gateway.
Remote HMIs and VB/VBA applications including Microsoft Office can use
remote OPC to communicate to RSLinx Classic Gateway for data collection.
This allows you to have multiple distributed computers performing data
collection without having RSLinx Classic installed on each machine!
In addition to the capabilities provided in the RSLinx Classic Professional
version, RSLinx Classic Gateway offers remote connectivity to:
• Multiple RSView32, FactoryTalk View SE, and FactoryTalk View ME
Station clients accessing data through one RSLinx Classic Gateway
(remote OPC).
• Remote computer running RSLogix connecting to a plant network
over a modem for online program changes.
• Remote Microsoft Office applications showing plant floor data such as
Excel.
• A web page showing plant floor data when the web server and RSLinx
Classic are on separate computers.
This section outlines the main tasks you need to perform to use the RSLinx
Classic software. The quick start information included in this section is
intended to be a high-level, conceptual overview. When you are ready to use
RSLinx Classic software, follow the detailed procedures found in the Quick
Start, which is located in the RSLinx Classic help. To access the Quick Start,
click Help > Quick Start from within RSLinx Classic. For information about
specific controls on RSLinx Classic windows and dialog boxes, right-click any
control.
A driver is the software interface to the hardware device that will be used to
communicate between RSLinx Classic and your processor. To configure a
driver in RSLinx Classic, click Communications > Configure Drivers. The
Configure Drivers dialog box appears, which is used for adding, editing, or
deleting drivers. Click a driver to configure from the Available Driver Types
list, click Add New, and complete the information required in the driver
configuration dialog box that shows. The driver configuration dialog box

Step 2 Configure a topic
After you complete the driver configuration, the driver name will appear in
the Configured Drivers list.
In RSLinx Classic, a project is a storage container for one or more topics, and
a topic represents a specific path to a processor. By grouping topics together
in a project, you can make multiple topics available at the same time. To create
or edit a project in RSLinx Classic, select File > Open Project (opens the Open
Project window). To create or edit a topic, select DDE/OPC > Topic Configuration (opens the DDE/OPC Topic Configuration window). If you
attempt to create a topic without creating a project, RSLinx Classic creates
default project for you.
If you selected Configure New DDE/OPC Topic by right-clicking a station in
RSWho, the Topic Name field is pre-filled for you. RSLinx Classic starts with
the name of the program running in the processor, and if this topic exists, it
adds a number to the end until it finds one that does not exist. If there are any
spaces, it converts them to underscores (_). You can change the topic name
RSLinx Classic selected for you.

on the Windows clipboard. Some packages support the ability to paste links
from the clipboard. The Copy to Clipboard function can be used with these
applications only.
Select the topic you just added in the DDE/OPC Topic Configuration dialog
box, and browse for the address string for your request.
clipboard
Rockwell Automation Publication LINX-GR001W-EN-E - March 2021 13
The Copy to Clipboard function only establishes hot links from RSLinx
Classic, the DDE server, to a Windows DDE client application. The Data Table
Address, Block Size, Columns per Row, and selected topic are maintained
from the last time that you used this function. Changing these values has no
effect on the last established link.
Most Windows applications support a Paste Link operation, and this feature
is generally located in the Edit menu.
Go to your application program that supports the Paste Link function. For
example, in Microsoft Excel, click an open cell in a spreadsheet where you
would like to place the data, click Edit > Paste Special, click Paste Link, and
click OK. The hot link is pasted into the spreadsheet at the location you
selected and begins to update. If you click Paste, instead of Paste Link, the
item string will get copied.
