When attempting to add a downstream device to an SSC the error "exception of type \'Feenics.Keep.DomainModel.KeepException\' was thrown"
EcoStruxure Access Expert

The SSC has a limitation of 32 downstream devices no matter what port(s) are being used
either RS485 or virtual.
The SSC specification data sheet indicates the SSC can manage up to 64 downstream devices. However, R&D has corrected our understanding of this limitation which is only 32 downstream devices.
Attempting to add a 33rd downstream device will result in the \'Feenics.Keep.DomainModel.KeepException\' error.
An additional SSC or Mercury upstream controller will be necessary to commission greater than 32 downstream devices.
"The SSC can support a Total of 32 downstream devices no matter what port they are connected to
either RS485 or Virtual. The SSC can also support 64 doors total."
