    • An information processor capable of ensuring time synchronization accuracy, ensuring EtherCAT command consistency, and easily developing the software based on a 2-port configuration even when a communication path error occurs includes: an arithmetic section; at least two communication sections each including a transmission section and a reception section; and a redundant communication control section that controls a communication path between the arithmetic section and the communication section. The redundant communication control section includes: a communication path state determination section that determines a network path state; and a redundant path switching section that switches connection between the arithmetic section and at least two communication sections. The network provides a logical ring topology for a packet communication path. The redundant path switching section functions based on the communication path state determined by the communication path state determination section and changes a connection path between the communication sections and a communication path between the communication section and the arithmetic section.
    • 一种信息处理器,能够确保时间同步精度,确保EtherCAT命令一致性,并且即使发生通信路径错误,也可以容易地开发基于2端口配置的软件,包括:运算部分; 至少两个通信部分,每个通信部分包括传输部分和接收部分; 以及控制运算部和通信部之间的通信路径的冗余通信控制部。 冗余通信控制部分包括:通信路径状态确定部分,其确定网络路径状态; 以及冗余路径切换部,切换运算部与至少两个通信部之间的连接。 网络为分组通信路径提供逻辑环形拓扑。 冗余路径切换部基于由通信路径状态判定部确定的通信路径状态起作用,并且改变通信部之间的连接路径与通信部与运算部之间的通信路径。
