PNP is sourcing. NPN is sinking. You generally connect NPN to ground and your PLC(or any load)input. With PNP you connect to V+ and to your PLC. Your PLC (load) should have the same ground or V+. Sourcing (PNP) provides a path to +24DC generally. Sinking (NPN) provides a path to 0V DC.

What do you mean by sourcing and sinking?
A sourcing output supplies current or voltage to the load. The output would be hooked to one side of the load, and the other side is grounded. A sinking output works by pulling the voltage or current to ground. In this case, the load is connected to the 'hot' power supply terminal, and the other end is connected to the sinking output. When the output goes active ("goes low"), current flows from the power supply, through the load, then to ground via the output terminal. Sinking outputs are sometimes called 'open collector' outputs. You can visualize it this way: Take a light bulb and hook one lead to the chassis of your car. You just grounded the load. Now take a wire and hook it to the positive battery terminal. When you touch the battery wire to the bulb, it lights. You are 'sourcing' current to the bulb. Now, connect the bulb to the positive battery terminal. Take a wire and connect it to the car's frame (ground). The bulb already has a voltage supply - the positive battery terminal. When you touch the ground wire to the bulb, sinking current to ground, the bulb lights. The big deal here is IC's that sink current typically have much greater current capability than those with sourcing outputs. So why even bother with sourcing outputs? Their main claim to fame is the load can be ground-referenced, which is very desirable in some situations.

Describe the difference between a sourcing input and a sinking input?
An NPN or sinking output accepts voltage and sinks it to ground to complete the circuit. A PNP or sourcing output sources voltage and the external circuit sinks it to ground to complete the circuit. A sourcing circuit would be drawn as voltage->switch->load->ground. A sinking circuit would be drawn as Voltage->load->switch->ground. In these cases, the switch could be a transistor.
Sinking and sourcing capability of microcontroller?
Sinking and sourcing current refers to current going into and out of the MCU (respectively)
What is the difference between npn and pnp proximity sensors?
No worries. The important thing here is that this module is simply reading a voltage from the sensor with reference to the ground of that sensor. This means that this module is always going to be a sinking device, and will be always be sinking small amounts of current from that sensor. This means, that your sensor is going to be powered externally and we will simply be reading the output voltage from it. Here is a link to a knowledgebase article about sinking and sourcing current. I hope this helps to clarify.
Would a relay be wired differently for a sourcing and sinking output module?
Yes. For sourcing output, the relay coil is wired to (common or ground) and the output terminal. For sinking output, the relay is wired to (voltage supply or hot) and the output terminal.
