2. Reference CWSERV from a Networked NT Client

Once you have setup the DDE Share on the server and CWSERV is running, you can access CWSERV from a client node. The syntax is slightly different than if CWSERV were running locally. The Service or Application name becomes the node name together with NDDE$. The topic name is the DDE Share name you just created. The Item name remains the same as it would locally.

Example in Microsoft Excel

When accessing CWSERV from EXCEL, you must put the Service/Application and Topic names in single quotes because of the '$' characters.

To access the value of the point, GEF_DEMO_ASETPT, from the node ALBP64, type the following:

'\\albp64\ndde$'|'CWSERV$'!GEF_DEMO_ASETPT.value
