Sorry, I checked up with the manual, but I can't get the required information.

Can you tell me how to connect a NPN and PNP type sensor in the above mentioned CPU I/O's

Thanks ivo.maenen, i got the answer this time, as you said only PNP type sensors can be used in the above mentioned CPU, not NPN.
