  • System and method for controller redundancy and controller network redundancy with ethernet/IP I/O
    Patent number: 9699022
    Abstract: An apparatus includes a first controller having at least one interface and at least one processing device. The at least one interface is configured to communicate with a second controller and with a controlled network having multiple EtherNet/IP-compatible input/output (I/O) modules and multiple EtherNet/IP-compatible controlled devices. The at least one processing device is configured to detect a fault associated with the second controller while the second controller is in communication with at least one of the I/O modules and at least one of the controlled devices. The at least one processing device is also configured, upon detection of the fault associated with the second controller, to resume the communication with the at least one I/O module and the at least one controlled device without the at least one I/O module updating the at least one controlled device to a failsafe condition.
