Measurement types and measuring ranges of the analog on-
board I/O
Introduction
The analog on-board I/O is set to voltage measurement type and measuring range ±10 V by
default for the inputs on channels 0 to 3. By default, channel 4 is set to resistance measuring
type and measuring range 600 Ω. If you want to use another measurement type or
measuring range, change the parameter settings of the analog on-board I/O with STEP 7
(TIA Portal).
Disable unused inputs to prevent disturbances that cause incorrect behavior (e.g. triggering
of a hardware interrupt).
Measurement types and measuring ranges
The following table shows the measurement types, the measuring range and the possible
channels.
