The following AutoMate program sequences can be used to interface to an

AutoMate Processor that does not support the AIN block. Over a period of four

scans, the program below inputs four channels from an Analog Rail module in

Rail mode.

Registers Used

0 Register that is configured to be updated at the end of scan.

40 Value input from channel 0

41 Value input from channel 1

42 Value input from channel 2

43 Value input from channel 3

44 Counter to select channel to operate this scan

45 Coils
