The SIMATIC HMI Thin Client Ex is designed for use as an operator station for terminal and client applications in hazardous areas, and in particular for applications for which the performance of the SIMATIC HMI Panel PC Ex is insufficient, or when the server is located in a protected area of the plant. The widely-used RDP and Real VNC protocols are supported.

Together with the digital KVM Box, the device functions as a flexible monitor with touch functionality for PCs e.g. in control rooms.
