26 I/O Configuration
1. Open the “Controller” folder.
2. Open the “I/O Configuration” folder.
3. Open slot 0 (controller).
4. Select the “embedded I/O configuration” tab.
The input groups are pre-arranged. Simply select the filter time you
require for each input group. You can apply a unique input filter setting
to each of the input groups:
The minimum and maximum response times associated with each input
filter setting can be found in your controller’s User Manual.
Analog Inputs
The MicroLogix 1100 has two 10-bit resolution analog input channels.
These channels are single-ended(unipolar) circuits and accept 0-10V dc.
Input words 4-5 contain the value of analog inputs(Word 4 : analog input
channel 0, Word 5 : analog input channel 1).
Analog Input Filter and Update times
The MicroLogix 1100 analog input filter is programmable. The slower the
filter setting, the more immune the analog inputs are to electrical noise.
The more immune the analog inputs are to electrical noise, the slower the
inputs will be to update. Similarly, the faster the filter setting, the less
immune the analog inputs are to electrical noise. The less immune the
analog inputs are to electrical noise, the faster the inputs will be to
update.
