    The user program is notified that the command reply is ready when the scanner sets an input image bit (I:s/15, where s is the slot number of the 1747-SDN). When this bit is set, the user program COPies the reply from the scanner’s M1 file. Allen-Bradley Publication 1769-UM001B-EN-P - October 2002...
