Important: When using RCLSs, you must also use the hardware
motion detector for the subject chassis (A or B or both). Do NOT
delete the motion detector switch (I/O module group 2, Figure 3.4
or 3.16) and do NOT write ladder logic for motion detection with
a resolver input (Figure 4.10).
Important: To set up your real or simulated ACAM, BCAM, and
TCAM on/off positions according to Figure 7.1 and Table 7.B, go
