there is a module with active diagnostics. To remove this diagnostic from the CPU, perform a hot
swap in the module with active diagnostic.
ATTENTION:
One Touch Diag (OTD):
This option is available only in the operation mode.
Diagnostics via LED
Hadron Xtorm Series CPUs contain a LED for diagnostics indication (LED DL). Table 7-2 illustrates
the meaning of each LED state.

Note:
Software Watchdog:
In order to remove the watchdog indication reset the application or turn the
CPU and on again. This watchdog occurs when the user application execution time is higher than the
configured watchdog time
Diagnostics via WEB
In addition to the previously presented features, Hadron Xtorm Series brings to the user an
innovating access tool to the system diagnostics and operation states, through a WEB page.
To access the CPU WEB page, simply use a standard navigator (Internet Explorer, Mozilla Firefox
3.0 or higher and Google Chrome 8 or higher) and type, on the address bar, the CPU IP address (e.g.:
http://192.168.1.1). Initially, the CPU information is displayed as in Figure 7-3:
