You must set the PROCESSOR TYPE to Logix5000. Refer to the RSLinx on-line

help for a discussion of each of the parameters on the form. Next select the

DVANCED COMMUNICATION tab on the dialog box. The following is displayed

after selecting the tab.

The C

OMMUNICATION DRIVER should be set to the ETHIP driver. Make sure the

OCAL option is selected in the LOCAL OR REMOTE ADDRESSING section of the

dialog box. You should not have to alter any data on this tab, as RSLinx knows

the communication path. Now click the A

PPLY button to implement the options

and to establish the topic.

You are now ready to use the DDE link in a DDE client application. The following

example shows how to define a DDE link in an Excel Spreadsheet. It is also

possible to define a DDE link in a Visual Basic program. Any other Windows DDE

client application could be used including SoftLogix and RSSql.

Defining a DDE link in Excel

This is the simplest DDE link to define and should be used to make sure the

Topic is defined correctly before using more advanced applications. Before

attempting to make the link, verify that RSLinx is running and that the DFNT

module is seen. To make a DDE link in Excel, enter the application, topic and

item elements as a formula into a cell. The format for the formula is as follows:

=APPLICATION|TOPIC!ITEM

The "|" character (piping symbol) separates the application and topic fields and

the "!" (exclamation symbol) separates the topic and item fields. For our example

topic of ProLinx1, the entry into the cell is:

=RSLinx|CIP_Sample!'RealData[500]'
