Los bits de control són códigos validadores, si un bit falla se indica con un 1 en la posición del bit erróneo.
Actualmente para perfiles de telegestión se comprueba lo siguiente:

Bit 7: Invalid measure
Bit 6: Synchronized meter during period
Bit 5: Overflow
Bit 4: Time verification during period
Bit 3: Modified parameters during period
Bit 2: Intrusion detected
Bit 1: Incomplete period due to power failure
Bit 0: No checks
