  • Remote I/O system and synchronization method in the same
    Patent number: 8369308
    Abstract: The object of the present invention is to provide a synchronization method that enables more accurate synchronization on a clock included in each I/O node, in a node that forms a remote I/O system where a master node and I/O nodes communicate each other.
    Type: Grant
    Filed: June 28, 2010
    Date of Patent: February 5, 2013
    Assignee: Sanritz Automation Co., Ltd.

  • I/O device, network system with I/O device and communication method in network system with I/O device
    Patent number: 8028112
    Abstract: An I/O device is provided to accurately synchronize clocks between nodes to have a device driving signal directly made out from the clocks, so that operation timing can be synchronized between the nodes regardless of a processing flicker on a host computer and a delay in a communication channel, and so that sending and receiving of a communication frame between the nodes, updating of contents of the communication frame, etc. can be efficiently performed.
