Configuring
9.9 Configuration of digital inputs/outputs (X142)
Configuring an oversampling DQ
1. Select the operating mode Oversampling DQ for the required channel.
Figure 9-24 Oversampling DQ
Note
Extending the configuration limits
A maximum of eight oversampling DQ can be configured at the inputs/outputs of the X142
interface. If the oversampling DQ at X142 are not sufficient for your needs, you can increase
the configuration limits with time-based IO modules, for example:
• ET 200SP distributed I/O system: TM Timer DIDQ 10x24V
(https://support.industry.siemens.com/cs/ww/en/view/95153951)
• ET 200MP distributed I/O system: TM Timer DIDQ 16x24V
(https://support.industry.siemens.com/cs/ww/en/view/95153313)
Inversion
You can invert the 24 V signal to adjust it to the process. By default, the signal is not inverted.
High-speed output (0.4 A)
If you select the high-speed output option, the digital output is switched alternately to
24 V DC and ground. Allows for extremely steep edges (output delay in the 1 μs range).
To allow signals pending very briefly to be output by oversampling DQ (for example level of
0.1 ms), you must operate the output as a high-speed output.
The rated load is reduced from 0.5 A to 0.4 A with this operating mode.
Further information
You can find more information on the Oversampling DQ operating mode in Assignment of
the control interface (Page 191) and Assignment of the feedback interface (Page 192).
