Why does the Input count range for the ADU205 Compact I/O module change after converting from
a Compact 984-A145 PLC to a Compact 984-E275 PLC.
The input count range for the ADU205 Compact IO module is defined as 2049-6143 for an input range of
-20mA to +20mA. When the PLC type is changed to 984-E275, the input count range is changed and the
module input irange s no longer valid for the application.
According to the 'Modicon A120 Seris I/O Modules User Guide', this is a normal behavior for the module.
The problem is due to the different input resolution used for the 984-E2xx Compact PLC.
To resolve the problem:
- Open the rack view
- Click on the BADU205 module in the rack view.
- Clcik on the button that is located next to the 'Card Config' textbox.
1.) Selecti the option for 13-bits resolution with the channel configured as -20mA/+20mA. This will provide an
equivalent input count range with that obtained from the Compact A145 PLC..
