It is a real-time distributed processing network that enables simultaneous effective "memory sharing (data sharing)" and "I/O control" with reduced wiring and ultra-high speed.
CUnet is a remote I/O control network with a "multi-master: multi-slave" configuration. Up to 64 CUnet ICs can be connected on a single network, and communication between the master and slaves is always automatic. The CUnet ICs are equipped with 512 bytes of memory for both master and slave ICs, and since it is a data-sharing type network, once a communication cycle is completed, the memory information of all CUnet ICs becomes the same (data sharing). Therefore, the CPU connected to the master IC can control the I/O of each slave simply by reading/writing to the memory of the master IC. The network connection uses multi-drop wiring with RS485, but by using a HUB-IC (MKY02), T-branching and wiring extensions are also possible.
