Each input port is provided with its Pin number 
 
 
 
 
 
 
 
 
 
in Mach3/UCCNC at Ports & Pins has to put a hook in Active Low. 
When the limit switch is actuated, it internally switches to ground and Mach3 detects a 
response at the input. PNP sensors switch with the switching voltage so they are also direct 
connected.
