Figure D.1: NPN Interface to an MDI Sinking Input

'set IO1 to Limit+, Active LOW, sinking
'enter program mode at address 100
'label program AA
'move relative x distance
'hold program execution until move completes
0 'call subroutine AB if I1 = 0 (limit reached)
1 'branch to AA if I1=1
'Label Sub AB
'Absolute move to Pos. -10000
'hold program execution until move completes
'end program
'exit program.
