Convert a Wonderware InTouch project to RSLinx Classic

Start the Wonderware driver and select

Configure > Topic

to open a list of configured topics.

Select each topic name, and click

Modify

to open the actual topic configuration dialog box. Note the

PLC Node Number (Station Number)

and the

Update Interval (Poll rate)

for each configured topic. Disregard any other information.

Install RSLinx Classic and configure the driver you will use to connect to the processor.

Configure a topic in RSLinx Classic to exactly match each topic configured in Step 1 (misspelled topic names result in errors when attempting to run the project).

Start InTouch WindowMaker and select

Special > DDE Access Names

. A dialog box opens containing configured access names. There is at least one DDE Access Name for each Application\Topic name combination.

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.
