Introduction
Rockwell Softwares RSView is one of many HMIs that can be used as an OPC Client to connect to an
OPC Server. There are two versions that we will cover here, RSView32 and RSView SE standalone. The
purpose of this document is to show the user how to make an OPC connection to TOPServer with the
RSView products.
The document is geared to the new user, although the experienced user may find value in this document as
well. We make the assumptions that the user 1) has a valid installation of RSView32 or SE, 2) has a valid
installation of TOPServer, 3) has TOPServer properly configured for communications to the PLC.
TOPServer is a product of Software Toolbox and may be referred to as the server or OPC Server.RSView is a product of Rockwell Software and may be referred to as HMI, client, or OPC Client. You
will also see OPC items referred to as tags or items. Also note that while it is not covered here nor is it
recommended by Software Toolbox, the server can also act as a DDE Server to RSView.

Connecting RSView32
The following steps will show you how to make an OPC connection from RSView32 to TOPServer. This
was done using version 6.50.07 of RSView32.
Start a New Project
First, open a copy of RSView32 and start a new project.
Figure 1
Save the file with a descriptive name.

This will open your new project in Edit Mode.
Figure 3
Create a Device Node
In RSView32 double-click on the System folder and then double-click on Node in the Project Control Panel.
If you have multiple devices in the server project, you may want to create multiple nodes in RSView and link
them to the devices in the server.

This will show your node assignment screen.
Figure 5
Select a data source, in this case OPC Server, check the Enabled check box and give the source a
meaningful name. Then we will browse for the server.

Browse For Available Servers
To browse for the server that you want to connect, click the button to the right of the Name text box.
Figure 7
This will show your list of available servers in the OPC Server Browser window. Select
SWToolbox.TOPServer from the list of Servers and click OK.
Figure 8

Select the Type of connection you are going to make to the server. Select Local for connection to a server
on the same PC. Select Remote to connect to a server running on another PC. This will enable the Server
Computer Name or Address field. You can enter either a computer name or IP address for the PC running
the server. You will also want to set your update rate to 0. This tells RSView that the server will use the
fastest possible rate to send data. If you design a large RSView project with multiple nodes, you may want
to slow down the update rates of your nodes.
Figure 9
RSView allows you to create the node with or without an Access Path. By leaving the Access Path blank
RSView can link to any tag within the server from this node. This means you can access tags from multiple
devices in the server application. Had we entered an Access Path, only tags from a single device could beaccessed through this node. Check "Enabled" so that the node will connect to the server when you run
your RSView project. Click Accept and Close. This will show your server in your node list. Click Close.

Create a Tag
Next, we need to create a tag(s) to access the data in the device(s). Double-click on the System folder and
then double-click on Tag Database in the Project Control and open the Tag Database dialog box.
Figure 11
This will show your tag database dialogue.
Figure 12

Page 10 of 23
In the Tag Database, enter the tag name and description information and select the tag type. Set your
minimum and maximum values as needed. In the Data Source section Click on the Device radio button.Then click the Node Browser button.
Figure 13
This will display your Node Browser window.
Figure 14
8/2/2019 TOPServer to Rockwell Software Connectivity
11/23
Page 11 of 23
Select the node name, in this case TOPServer, and click OK to assign the node to the tag you are defining.
In our example, we have only TOPServer node that we have added. This will bring you back to the Tag
Database tag definition. Click on the Address Browser button located to the right of the Address field.
Figure 15
This will show you the OPC Address Browser.

Expand your server Node and channel that contains the device and highlight the device to show the tags in
the right pane. Then select the tag you want to read in the right pane. Click OK. Remember, we are using
predefined tags from TOPServer in this instance.
Figure 17
This will bring you back to the tag database, showing you the access path to the tag.
Figure 18

Click accept to add the tag to the tag database. This will show you the tag in the tag list in the bottom right
pane. Click Close to close the tag database.
Figure 19
Check the OPC Connection
We need to verify the OPC Connection to the server. To do this, double-click Tag Monitor in the System
Folder.
Figure 20
8/2/2019 TOPServer to Rockwell Software Connectivity
14/23
Page 14 of 23
This will show you the Tag Monitor dialogue.
Figure 21
Enter the Tag Name or names that you want to check. In this case we entered "Tag1" which is the name of
our tag that we added. Hit the Enter key after typing in the tag name. You should see a State of "valid" in
the Tag Monitor window for the tag and a Value that is ramping or incrementing very quickly. If you see
this, you have established a good OPC connection to the server from RSView32.

Connecting with RSViewSE
The following steps will show you how to make an OPC connection from RSViewSE standalone to
TOPServer. This was done using version xxx of RSView Studio.
Open a New Project
Open RSView Studio and choose the appropriate type of application and click Continue.
Figure 23

Create a new application, giving it a descriptive name and any description necessary. Click Create.
Figure 24
This will load your blank Studio screen.
Define an OPC Server
To define an OPC Server, do the following. First, click File|New|OPC
Figure 25

Page 17 of 23
This will open the OPC Data Server Properties dialogue.
Enter a meaningful name and description (optional) for the Server. Select if the server will be on the local
computer or a remote computer. If remote, click the browse button in the Computer hosting the serversection. If not the box will be inactive with localhost populated in the field, then skip to browse for the
server.
Figure 26
This will bring up the network browser. Browse to and select the computer where your OPC Server resides.
The computer name will then show in the text box in the Computer hosting the server section. Now we
can browse for the OPC Server.

Browse For Available Servers
To browse for the server, click the browse button beside the OPC Server Name (ProgID) text box. This will
open the OPC Server browser window.
Figure 27
Select Software Toolbox OPC Power Server and click OK. This will populate the server ProgID in the text
box. Alternatively, you could just type the ProgID, SWToolbox.TOPServer, into the text box without
browsing. Click OK to continue.

You will see an informational message at the bottom of RSView alerting you that the server is now active.
Figure 29
Create a Tag
We now need to create the tags in RSView to read data from TOPServer. At this time, if it is not already
open, then open your Application Explorer by clicking the second icon from the right in the toolbar. Right
click on HMI Tags|Tags and click open.
Figure 30
This will open your tag database window. Here you will need to define your tag.

This will populate the tag address field. Click Accept to add the tag to the database and it will add the tag to
the list in the bottom pane. Click close.
Figure 33
Test the OPC Connection
To test your OPC connection, you will want to set up a new simple display with a single tag with a known
changing value. After creating your display, you will want to launch the runtime to verify the changing data
from your tag.
