RSView32 User’s Guide
Once you have created the node, assign it to a tag in the Tag Database
editor. The address tells RSView32 where in the node to get the data.
Address: N7:12
The PLC-5
® programmable controller called
PLC_HVAC1 has been previously set up as a DDE/
OPC topic in RSLinx; N7:12 is the address in the
PLC-5/250.
If you don’t include the Access Path when configuring the node, you
can enter the tag’s address as [PLC_HVAC1]N7:12.
The figure below shows how the tag looks in the Tag editor.
Creating a DDE node
A DDE node allows you to assign a logical name for each DDE
application and topic you wish to communicate with. The DDE node
name can then be used throughout RSView32.
