Using PCIS-DDE With InTouch
The last step is to define the DDE item name. In this field, type the item
name for the desired data value in the PCIS-DDE server. Please refer to
the chapter 4 for the valid item names of each NuDAQ PCI-bus data
acquisition cards. For example, to access the digital input value of
PCI-7200 module, type PDI in this field.
Note: It is important to understand that the "tagname" is the name used
within InTouch to refer to a data value. The Item is the name used by
I/O DDE Server program to refer to the same value. These names
do not have to be the same, however, it is recommended when
applicable to use the same names.
