SSC600 has limited amount of resources to ensure stability of the protection and control application. In-built tool estimates the configuration load and ensures that too big applications can't be created. When modifying the Application Configuration, the estimated load can be found from the PCM600 Output Window. If the estimated load exceeds 100%, it is not possible to write the configuration to the device.
As long as the amount of received IEC 61850-9-2LE streams is 20 or less, SSC600 can manage all feasible protection applications. When amount of received streams get closer to 30, the amount of available protection function instances is limited. Even with 30 streams normal protection applications are still possible. For example busbar differential protection, backup current/voltage protection and circuit breaker failure protection in the same application.
