ABSTRACT:
A multipoint data collection system uses multiple parallel data buses connecting a central controller to addressable sensor interfaces to permit any sensor to be connected to a central controller over any one of the data buses. Both ends of each data bus are connected to the central controller, allowing sensor interfaces to be addressed even if all data buses are cut. Faults on a data bus and defective sensor interfaces may be bypassed through one or more bypass buses that may be addressably switched into use as desired.
