Publication GMLC-5.2 - November 1999
Using the Dedicated Discrete Inputs 689
The recommended ladder logic for homing axes is shown below. Only
axes 0 and 1 are shown, but axes 2 and 3 are handled in the same manner.
The Rack Address in the motion controller is set to 5 and the Starting
Group parameter to 0. Thus the dedicated discrete RIO bits appear in I/O
group 1 of rack 5 (I/O:051).
