ain8pt 
Generic 8 point AIN module 
Description 
The ain8pt I/O module provides eight I/O channels from Generic 8 Point Analog input 
hardware. Data for each of the eight I/O channels may be connected to user-defined 
variables with the I/O connection editor. Connected variables are updated continuously with 
data from the Generic 8 Point Analog input hardware. 
Set the ain8pt module_address to match the address switches on the Generic 8 Point 
Analog input hardware. 
The ain8pt I/O module may be used in place of any other 8-point analog input-type module. 
The ain8pt module type is a useful selection early on in the system design stage before the 
final selection of the specific analog input module is known.
