Use the wiring arm (1771-WF) supplied with the QDC module to wire I/O
devices (Figure 2.3). The wiring arm lets you install or remove the QDC
module from the I/O chassis without rewiring. Wiring arm terminals are
numbered in descending order, from the top down, starting with terminal
18 (Table 2.B).
