Output type and output ranges of the analog on-board I/O
Introduction
The analog on-board I/O is set to voltage output type and output range ±10 V as default for
the outputs. If you want to use another output range or output type, you need to change the
parameter settings of the analog on-board I/O in STEP 7 (TIA Portal).
Output types and output ranges
The following table shows the output type and the corresponding output ranges.
Table 5- 4 Output type and output ranges

Parameters of the analog on-board I/O
Parameters of the analog on-board I/O
You specify the properties of the analog on-board I/O during parameter assignment with
STEP 7 (TIA Portal). The tables below list the parameters that can be set for inputs and
outputs, respectively.
When parameters are assigned in the user program, they are transferred to the analog on-
board I/O via data records with the WRREC instruction, see section Parameter assignment
and structure of the parameter data records of the analog on-board I/O (Page 150).
