The ACOS ET is VIVAVIS' central engineering and parameterization environment for the ACOS 7 RTU platform. Rather than configuring each field device through separate vendor-specific tools, engineers use one wizard-driven Windows application to define device parameters, map communication protocols, assign I/O, and manage security certificates — then deploy configurations to field RTUs via microSD card or network connection.

How does ACOS ET streamline RTU configuration?

The tool provides a graphical engineering interface with device wizards that guide the user through communication topology, signal mapping, and protocol selection. Hardware diagnostics, online process values, and event logs are accessible from within the same environment — eliminating the need to switch between programming software, terminal emulators, and SCADA editors during commissioning. Mass data import/export via Excel CSV speeds up bulk signal mapping.

How does multi-user engineering work?

ACOS ET supports multi-user workflows through SVN-based version control with an extended role concept. Engineers can work on separate project sections simultaneously, with Active Directory integration managing authentication and access rights. A central certificate repository ensures consistent security credential handling across all users and target devices.

How does ACOS ET integrate with the SCADA system?

The tool exchanges data directly with VIVAVIS' HIGH-LEIT SCADA system — device configurations, signal lists, and communication parameters created in ACOS ET are imported into the SCADA database without manual re-entry. This eliminates a common source of commissioning errors where the RTU configuration and the SCADA database diverge.
