Sample AutoMate Program
The following AutoMate program sequences can be used to interface to an
AutoMate Processor that does not support the AIN or AOUTblocks. Over a
period of four scans, the program below maps registers 40 through 43 to the
four channels of an Analog Rail module in Rail mode.
Registers Used
0
Register that is configured to be updated at the end of scan.
40 Value to output to channel 0
41 Value to output to channel 1
42 Value as input to channel 2
43 Value as input to channel 3
44 Counter to select channel to operate this scan
45 Coils
Beginning of the Scan
If channel 2 was selected at the end of last scan, read the data that has now
come back into register 42. The channel select bits are cleared, but the
underĆrange and overĆrange bits are left for later testing.
