Does the RTU protocol have encryption?

Yes! Encryption function can ensure the security of equipment data, most manufacturers of RTU encryption function can only be to the operator for the special network card, more trouble, the general small business with this can not be done, you must go to the headquarters of the operator to deal with. I know a RTU does not have to be so troublesome, is Xiamen for that production of the WCTU, which has a PLC, RTU, DTU all the functions of its encryption function in the initialization of the preparation of an optional encryption method to ensure security. Moreover, it has the functions of collecting analog variables and logic control data, replacing the functions of PLC and RTU. It can also be dispensed remotely by cell phone SMS, which is convenient for later maintenance. If the center network disconnection or failure can not receive data, WCTU will automatically send the data to the designated cell phone for data backup.
