Since we are emulating a quarter rack, consisting of Group 2 and 3, the input bit addressing is from
I:012/00 to I:012/17 and I:013/00 to I:013/17. The output bit addressing is from O:012/00 to O:012/17
and O:013/00 to O:013/17. You also have two input words I:012 and I:013, and two output words
O:012 and O:013.
Configuring for Block Transfer Operations
You now have the choice of selecting any of the four slots and each slot can be a Block Transfer Read
(BTR), Block Transfer Write (BTW) or both. For this example, both BTW and BTR for Group 2, Slot
0 will be used.
First, we set up the BTR by clicking the check box in Group 2, Slot 0. The following menu will appear.
Always use this tool for building RIO tags. Do NOT attempt to build these tags while creating panels
in the Panel Editor.
If you click the Auto name check box, the tag name will be generated by the system and appear in the
Tag name field. Note that the tag name is cryptic, it describes the variable as a BTR, located at rack 01,
Group 2, slot 0. The naming scheme will help you remember the racks that are in emulation mode. See
the following example.
Click the OK button to accept the Tag Name. The check box now appears with a check mark inside,
indicating it has been checked.
