I have set up a rapid scada server that collecting data from multiple device for electric system. I also calculated some summary info, e.g. quantity of device working normally, quantity of device offline, etc…
My customer has another SCADA system than monitor the whole building.
Option 1. Via external database as manjey73 said. See this link.
Option 2. We can develop OPC UA server or Modbus Slave driver for Rapid SCADA by a custom contract.
