  • Patent number: 10027747
    Abstract: A terminal communication apparatus has a terminal communication control portion rendering an immediate communication control portion sequentially transmitting serial data to another terminal communication apparatus bitwise when receiving a packet as bitwise serial data and a normal communication control portion performing processing on the packet after accumulating the serial data until the serial data reaches a packet length when receiving the bitwise serial data switchable, performing processing with the immediate communication control portion in a case of receiving a time adjustment packet containing time adjustment data posting a timing of synchronization in the other terminal communication apparatus and performing processing with the normal communication control portion in a case of receiving a packet other than the time adjustment packet. Thus, synchronization of control object devices can be enabled without previously investigating communication delay times.

  • Patent number: 9841739
    Abstract: A motion controller device and a communication method for the motion controller device are provided to reduce the large number of man-hours that are required for making communication settings and wiring design in large-scale systems. The motion controller device and communication method improve the degree of freedom for communication line connections by switching the two transmission paths on the transmitting and receiving sides of the communication ports contained within a central communication device and a terminal communication devices for full duplex communications. The motion controller device and communication also ensure the response performance required in the devices being controlled by way of the terminal communication device that autonomously and dynamically switches the communication paths according to the volume of communication data on the communication line along this type of network.

  • Patent number: 9459617
    Abstract: A motion controller is provided which improves system responsiveness without having to raise the arithmetic capacity of a master controller or to boost the communication speed of a network. The master controller 1 uses a program analysis unit 1g to separate, from a control program designating a tolerable delay time for operating control target apparatuses, a slave use program to be executed by a slave controller in a manner not to exceed the tolerable delay time, and to create slave-to-slave communication setting information needed by the slave controller to execute the slave use program. Through slave-to-slave communication, the slave controller 2 acquires input/output information from another slave controller. The slave controller 2 also uses a slave use program execution unit 2f to execute its own slave use program.
