Analog Input Module
9-4
In the current input modules, the ranges that can be selected are: ±20 mA (default) and 4-20
mA.
In voltage input modules, the ranges that can be selected are ± 5V (default), 0-5 V and 1-5 V.
Keep Last Value (KLV) and Predefined Value (PDV)
Each input can be configured to KLV or to a PDV. This value is shown to the user application
program in the event of AI module failure. The predefined value can also be used during
normal operation to force a value that masks the actual input value. In this case the program
user will get the PDV instead of the actual input value.
AI Module Configuration Options
The AI module features which can be configured are listed in the table below. Some parameters
are per module and some are per input.

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.
