The COMPISO SCADA is an integrated part of the COMPISO P-HIL System Unit. The COMPISO SCADA

(Supervisory Control and Data Acquisition) System has the following roles:

System Configuration:

During system configuration, the complete hardware setup for a P-HIL application is done. It will be defined to what output rail the digital amplifier outputs are set and in which mode the Digital Amplifiers will work.

System Parameterization:

In the COMPISO HIL system, many parameters can be set to prepare the system for a dedicated application. Before the system goes online, those parameters are set and stored.

System Online Operation:

With the help of the SCADA GUI, the system is powered up and guided during operation. After a certain application is finished, the system is shut down by the SCADA.

System Monitoring:

During online operation, the system is monitored by the SCADA. It contains event and error monitoring and it traces system parameters like temperatures, voltages and currents during online operation. In an unsafe condition, the SCADA is able to shut down the system.

SCADA Topology


Every COMPISO System Unit is connected to the SCADA PC via an Ethernet Network. This is a separated network that is a part of the COMPISO P-HIL System. It is not allowed to connect this network to a public office network. The SCADA is connected to the following components:

CDA (COMPISO Digital Amplifiers)

The SCADA PC configures and parameterizes every CDA in the P-HIL System. During operation it monitors the state of the CDA and records process parameters.

HIL (Hardware in the Loop System)

The SCADA PC checks the emulation model that is loaded into the HIL processor. It proves that the loaded emulation model is compatible with selected operation mode (3 Phase AC-Mode, DC-Mode, etc.) of the digital amplifier. After the power path in the system has booted it releases the HIL operation.


Every CSU has an integrated PLC that controls the operation of the power path. The SCADA PC initiates power up und power down cycles driven by the PLC. The PLC reports the state of the power path and occurring alarms to the SCADA PC.

Grid Converter (optional control)

The SCADA PC can be connected to the grid converter. The SCADA PC parameterizes the grid converter and monitors its operation and records process parameters.

Parallel operation


When several COMPISO System Units operate in parallel, the SCADA PC is connected over a Main Switch to all COMPISO System Units within the P-HIL System. The SCADA PC configures the parallel operations and secures that all units are parameterized and operated in safe conditions.

SCADA Remote support (Optional)


As an option, the SCADA PC will be equipped with a second Ethernet interface to be connected to a local office network. This enables the EGSTON Help Desk to have access to your P-HIL System and provide online support.
