This protocol allows communication with most Ethernet I/P devices. To create channels, you select the new device you created with the Ethernet/IP protocol, then select an I/O Type and put the tag name in the Quick Note / Special / OPC column of the channel table. The D# and Channel # parameter does not matter. For outputs you have to select the data type in the I/O Type. For inputs it does not matter and you can just select Read Input as the I/O Type as the PLC tells DAQFactory what the data type is in the response. Output channels can be read using the same channel if you don't want a separate read and write channel for each tag.
Tag names (a.k.a. "Request Paths") need to be something like this:
Program:MainProgram.Timer_1.ACC
For Allen Bradley PLCs most tags often will start with:
Program:MainProgram.
but it depends on the scope in the PLC. Figuring out the naming is probably the hardest part, but once you get one, the rest usually fall in place. Note that what you type in the Quick note / Special / OPC column is exactly what is requested using Ethernet/IP. DAQFactory does not massage the tag name at all.
