RSLinx – Training Guide 47
Training Section 6: Project, Topic and Alias
Configuration
After configuring your communications hardware and verifying its connection, you can
now configure a DDE/OPC Project and Topic to enable RSLinx to provide data to DDE
requests. The Topic contains the information necessary to communicate with the
intended PLC.
1. Click the File menu/Open Project, then click the New button.
Type in a project name, such as TEST and click OK.
Project names are limited to 49 characters. Spaces are converted to
underscores (_). If the Open Project dialog box does not appear, go right to step
two.
• When you create a project, you create a container for a number of topics;
exactly how many topics is up to you and the amount of disk space you have
available.
• It is usually best to add all the topics for a given scenario to a specific project.
You may select to not create projects and use the default only, but there are
advantages to grouping your topics into projects. Less of your computer's
resources are used because instead of loading all of your topics, you might
only load the ones you use for a specific acquisition or report.
Though you can create many projects, only one project can be used at a time.
