. By
changing this value, and associated with it object 2100h
AI Input Range
, other objects will be
automatically updated by the controller. The options for object 6110h are shown in Table 4, and no
values other than what are shown here will be accepted. The inputs are setup to measure voltage
by default.

– Object 6110h - AI Sensor Type Options
The allowable ranges will depend on the input sensor type selected. Table 5 shows the relationship
between the sensor type, and the associated range options. The default value for each range is
bolded, and object 2100h
