Configuring the DQ operating mode

DQ operating mode
1. Select the DQ operating mode for the required channel at interface X142.
Figure 9-12 DQ operating mode
Inversion
You can invert the 24 V signal to adjust it to your 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).
The rated load is reduced from 0.5 A to 0.4 A with this operating mode.
Interconnections
The technology objects that are interconnected with the channel are listed in the
Interconnections area.
If technology objects are interconnected, you can reach the respective technology object
through links (arrow icons).
Use the corresponding button to update the selection list. Updating may be required, for
example, if changes have been made to technology objects elsewhere in the project while
the channel configuration is open.
Further information
You can find more information on the DQ operating mode in Assignment of the control
interface (Page 191) and Assignment of the feedback interface (Page 192).
