For bulk configuration, one cannot calculate PLDOS like it is done for device configuration. As I said you may still get atom- or atomic layer resolved DOS, meaning that you can get dependence of DOS in certain directions by projecting on atomic layers, i.e., calculating a set of PDOS plot for each layer (given with a tag).
Alternatively, you can build a perfect device from your unit cell and do device calculations. In this case, you will be able to compute PLDOS as usual.
