With version 9 of the Aqasys process control system from Schraml, water supply and wastewater disposal plants can protect all data communication between the process control system, the visualization devices (workstation PCs, mobile devices and HMI touch panels) and the telecontrol stations against malware and hacker attacks. To achieve this, all sending and receiving components must identify each other with system- and device-specific digital certificates. Data transmission between the components of the central process control system and the telecontrol stations is SSL/TLS-encrypted. This is possible for GPRS/DSL connections, in the LAN and for DSL/VPN connections.
