Create a Wonderware InTouch project using RSLinx Classic

Install RSLinx Classic and configure the hardware you will use to connect to the processor. Configure at least one topic in RSLinx Classic for each PLC, with which your project communicates.

Start

InTouch WindowMaker

.

Select

Special > DDE Access Names

. A dialog box opens containing configured access names. If none of the access names are configured, click

NEW

. Enter

RSLINX

as the DDE Access Name to communicate to RSLinx Classic, and a topic name to match that configured in RSLinx Classic.

Select each access name and click

Modify

. A dialog box opens containing the application and topic name for that access name. Do not change the DDE Access Name, DDE Topic Name, Handling of initial data values, or when to advise server settings. Only modify the DDE Application/Server Name from whatever it is to

RSLINX

. Complete this process for each DDE Access Name in the project.

Start

InTouch WindowViewer

. If configured correctly, the project should be running using RSLinx Classic. If DDE errors occur upon WindowViewer start up, check the topics' configuration in RSLinx Classic and the DDE Access Names in InTouch. Make sure all application and topic names are spelled correctly and the topic is configured properly to communicate to a PLC. If no DDE errors occur upon WindowViewer start up but no data appears, the DDE configuration is probably correct. Check the hardware, cables, and configuration in RSLinx Classic for problems.
