Trigger-Based Logging

Clicking the trigger icon displays the trigger window.

Click on the 'New trigger' to add a new trigger action.

'Start logging' and 'Stop logging' can be added as trigger actions.

‘Log Time (sec)’ enables the logger to log for the given time after a trigger occurs.

‘Pre–Trigger Time (sec)’ specifies the duration for which pre-trigger data must be saved.

‘Debounce (msec)’ time is when the switch does not register another click, relevant when you use Digital I/P.

Click ‘Next’ to select the trigger type.

Select bus and trigger type and click ‘Next’.

Defining Trigger Conditions

1. Trigger by CAN identifier (Ident)– This option will enable the user to specify the CAN/CAN FD ID on which the trigger should be active.

ReXdesk allows the user to specify the CAN manually/CAN FD ID or import a DBC file.

1. Trigger by parameter– This option will enable the user to specify the parameter/signal value on which the trigger should be active.

ReXdesk allows the user to import signals from a DBC file.

1. Trigger by DM1 J1939 counter– This option will enable the user to set up a trigger based on the increase, decrease or change in the DM1 counter.

ReXdesk allows the user to specify the source address of the DM1 message, which the logger should be monitoring.

1. Trigger by digital channel– A digital trigger will be enabled only when the digital input is present in the configuration. Refer to Appendix 4 for setting up digital triggers in ReXgen.

Drag and drop the ‘Dig In’ tool to the channels in the configuration window.

Select the digital channel and sampling rate, and then click add.

Now, you can proceed with creating triggers based on the digital input.

This option will enable users to set up triggers based on the rising or falling edge or digital input changes. The default state of the digital bus is high.

When a trigger is present in the configuration, the Storage icon will change to indicate it.
