What is the Maximum Number of NI 9144 Chassis That Can Be Daisy Chained Together?Hardware: CompactRIO>>Controllers>>cRIO-9074
Problem: I know the NI 9144 chassis can be used in a daisy chain. Is there a limit to the amount that can be connected together? Solution: The theoretical maximum number of NI 9144 chassis that can be connected together is 65,535, as specified by the real-time Ethernet protocol. However, the number of chassis does not matter as much as the number of I/O channels being deployed. More I/O channels means that more data must be pushed over the network, which will slow down the scan rate of the system. In general, the processing power of the master controller for the NI 9144 will directly impact the number of I/O channels it can handle for a given scan rate.
