### Trace Values

Trace values are used for debugging purposes. You can set these values in your script and view them in real-time in the Cronus Zen software to see what is happening inside your script.

Code-Snippet

```
main {
    set_val(TRACE_1, get_val(XB1_RT));
}
```

In the example above, the value of `XB1_RT` is being sent to `TRACE_1`, which can then be monitored.
