SCADA (Supervisory Control And Data Acquisition) or HMI (Human Machine Interface) is an application interface that is mainly delivered with a PLC program and allows visualization and management of the automation system, as well as all the parameters necessary for its proper operation.

Along with the basic possibilities there are numerous others:

- Alarming

- Reporting

- Making/managing recipes

- Creating an automatic schedule (starting the process at exactly predefined time)

- Remote control (telemetry)

- The ability to determine the access level to the operator

- and many others

Depending on the needs of the client, additional functions that SCADA/HMI must contain are determined by client himself.
