"PLZDC received" is a scan from Buffalo, and PLZDC is an internal facility code, most likely a sorting or distribution centre. The scan means your parcel has physically arrived there and been registered. It is a routine checkpoint in the middle of the journey, not a delivery attempt.
This message by itself is normal. It is not an exception or a problem report. Parcels often pass through several sorting centres, and each one adds a scan like this. Only if the parcel stays on this line for longer than the previous steps took is it worth looking into.
The parcel is sorted and moved on to the next stage. That may be another Buffalo facility, a transfer toward the destination area, or a local delivery centre. The next scan will usually show one of these, often with another facility code.
