In communication networks, a self-contained data unit consisting of user data and control data is referred to as a datagram or data telegram.

Datagrams are referred to as telegrams in fieldbuses. The fieldbus telegrams, just like the postal telegrams known from postal technology, contain the user data in addition to the sender and destination address. In most fieldbuses they also have a data field for the cyclic block check (CRC).
