Sleep Mode
Each AI module can be switched by the user application program to Sleep Mode. In Sleep
Mode, the module does not function and the power consumption is minimized. During Sleep
mode the user application program will get the predefined values for each I/O.
Module Status and Diagnostics
In the event of AI Module failure, the I/O module ERR LED will be lit. The event is
registered by the CPU in the Error Logger. AI Module failure status is also visible to the user
application program.
In addition to the ERR LED, the module includes an Underflow (UDF) and Overflow (OVF)
LED for each input.
• When the UDF LED is lit, it indicates that the signal level in the corresponding input is
below the nominal range.
• When the OVF LED is lit, this indicates that the signal level in the corresponding AI is above
the nominal range.
