Some modes require a separation of the bus, as all of the gen-sets has to run. The bus tie breakers are controlled separately with ComAp controllers with bus tie applications. The entire application does not have a master controller, so in case any of the ComAp controller fails, another controller takes care over control. The system is also fitted with CAN bus redundancy, where the inter-controller communication plays a major role in entire power management. Once any of the can wire breaks, another CAN line takes care without any interruption.
