Description
5466-258 External Storage Devices
5466-258 depending on the system topology. A large number of multiprocessor nodes can be connected to a large (1,000-processor) system via a SAN (“big bus” model) to support distributed, integrated real-time systems for data acquisition, control, and data processing applications. and switching modules (L-modules, B-modules, and S-modules). The cost of communication speed decreases faster than the cost of pins and board space. Traditional communication is based on buses, which limits the number of processors.
Weak interactions between 5466-258 processor modules are based on messaging (Ethernet). Intermediate interactions are based on external storage devices used in the cluster (disks, tapes). Strong interactions between processor cores are based on direct reads to distributed memory and are implemented on SCI, which also supports weak interactions between processor modules.Strong interactions for SCI include small packet transactions (packets sent and responded to separated with echo).5466-258 Packet formatting includes the write xx, read xx, move xx, and lock commands. Here xx indicates the allowed data block length (number of data bytes, to the right of the packet header).
5466-258 through 3G, 4G or, WIFI, mobile phone hotspot, Ethernet networking, the remote PLC and the operator’s computer remote composition of a LAN, directly PLC program remote download and data remote monitoring. Support Siemens PLC, Mitsubishi PLC, Panasonic PLC, Delta PLC, Omron PLC, Schneider PLC, BUEFO PLC, YASKAWA PLC, Huichuan servo and so on various PLC.
