Binary Outputs
The Binary Outputs button in the Preferences view of an added I/O communication module BPlus or I/O module supporting device profile CiA® 401 or CiA® 404 opens the Binary Outputs view.

Note that changes in this view are not saved and applied by the I/O module until you exit the view. Use the drop-down list to link the I/O module's binary outputs displayed in the Channel column to the desired function:
- Not Used
The binary output is not linked to any function. - Error Output, Warning Output
The binary output of the respective I/O module is assigned to the binary output Error or Warning of the EasyNOₓ. If the binary outputs of the EasyNOₓ are activated (see Devices), the EasyNOₓ switches the assigned binary output of the I/O module if a corresponding monitoring function of an added device requires it. - Cat. Temperature Error NOx1 / NOx2
If the respective NOX monitor of the EasyNOₓ has detected a temperature error on the respective engine at at least one of the configured exhaust gas temperature measuring points near the catalytic converter, the EasyNOₓ switches the assigned binary output of the I/O module. - NOX Exceedance NOx1 / NOx2
If the provisional daily average of the nitrogen oxide concentration currently exceeds the configured level limit of the engine monitored by the respective NOX monitor, the EasyNOₓ switches the assigned binary output of the I/O module.
- Normal Operation NOx1 / NOx2
If, for the respective engine, normal operation has been detected by or signalled to the respective NOX monitor of the EasyNOₓ, the EasyNOₓ switches the assigned binary output of the I/O module.
