10.5 Safecard on Motherboard (SOM)

This application is used to monitor PC hardware (temperature, watchdog and fans) and to

display the current measured values. The application can be configured on a GUI, and

temperature monitoring, the watchdog function and fan monitoring can be enabled.

Your SIMATIC PC is equipped with three thermocouples, which are automatically detected

by the application.

1 Temperature range: You are here shown the current temperature and limit values. You can

toggle the temperature display mode to indicate either the current

temperature, or the min./max. values measured since the start of the

application. You can set a check box to enable polling or interrupt mode

for the temperature monitoring function.

2 Watchdog area: Here, you can configure the watchdog function in your monitoring

application. You can specify the watchdog time, assign an interrupt,

activate a PC reset and activate / deactivate the watchdog.

3 Fan area: In this area you can visualize the current speed of the fans.

The description of the driver and SOM program are available on the CD "Documentation and
