48 RSLinx – Training Guide
2. A topic is a pointer to a PLC, much like how your telephone number “points” to your
house. It also determines how fast or when data will be collected.
Topics may be configured in two ways :
• The preferred method is from an RSWho.
Right-click a station and select
“Configure New DDE/OPC Topic.”
• This method will create a NEW topic – to only see
or edit an existing topic, use the menu item called
DDE/OPC - Topic Configuration…
• Another way is to either use the Topic
Configuration icon.
A DDE/OPC Topic Configuration dialog box displays.
Click the help button in the dialog box for additional
information on DDE topic configuration.
Note: Topic Configuration is not available with RSLinx Lite.
