Special Feature of the Measuring Range Selection and Output Range Selection
You select the measuring type (current measuring or voltage measuring) of an
input channel via the wiring of the analog inputs (see Figure 13-10 ). You select the
output type (current or voltage output) via the wiring of the analog outputs (see
Figure 13-10).
