The SINUMERIK HT 8 operates according to the Thin Client principle. The operator software is installed on a SINUMERIK NCU/PCU. An Ethernet link is used to transfer screen contents from the NCU/PCU to the HT 8 and key information from the HT 8 to the NCU/PCU. The HT 8 display shows the same operator interface that is displayed on the standard operator panels of the SINUMERIK control system.

Hot swapping is available with the PN Plus connection box.

The operator interface can be customized if required (see SINUMERIK Integrate).
