2) System – Node – Select DDE server as data source
3) Name = VR06 (No gaps )
4) Application = RealTime_Viewer
5) Topic = TagService
6) Check enable in the box. (This node should be selected)
7) Now open the data base
8) Create analog tag with all the details similar to the tag at the recorder.
9) Select VR06 at the NODE
10) Write the tag address, this should be same as tag name at the recorder and Observer software.
For ex: analog input 1 AI1 should be written as _AI1 (Please note that underscore is required
before the name of the tag, otherwise data will be not exchanged.
11) Now open the tag monitor and configure for the above tag for checking of DDE with the tag.
If DDE is configured properly, then tag value should appear correctly at the tag monitor with state as
“VALID”. If any error message is available, then you have to repeat from step 1. Please note that before
checking tag monitor, real time viewer in PC should be in running condition.
