In the Logix family, most modules do not come with built-in screw terminals, so Removable Terminal Blocks (RTBs) or Bulletin 1492 Interface Modules (IFMs) must be purchased separately. You should carefully review the wiring requirements for your module using the online Rockwell Automation Literature Library resource (relevant links can be found in the Further reading section of this chapter). We cover RTBs in more detail in Chapter 15, Building a Robot Bartender in Logix, of this book.
Now that we have covered the basic Rockwell module types, we will go through an exercise where we will configure one using RSLogix or Studio 5000.
