The LHC_CIRCUIT component is used by the LHC_CIRCUIT project. This PVSS project is involved in the LHC operation. It allows displaying the QPS, PIC and Power Converters status in a common view based on the Electrical Circuit. It is also the only way for the QPS operators to connect on the QPS servers.
The PVSS component has to be installed via the fwInstallationTool into the PVSS project.
