BCC stands for blind carbon copy. ... The difference between the two is that, while you can see who else has received the email when CC is used, that is not the case with BCC. It is called blind carbon copy because the other recipients won't be able to see that someone else has been sent a copy of the email.

Cyclic Redundancy Check (CRC) Error indicates when data is corrupted. Calculating from all data, CRC validates packets of information sent by devices and verifies it against the data extracted, ensuring its accuracy. When sending packets over,BACnet automatically calculates and stores a CRC value for the packet.
