GE PQMII-T20 general module
Technical data of product parameters
The receiving node PQMII-T20 evaluates each of the redundant transfers. If no errors are detected in the first transfer, it is used to update the on-board memory and the second transfer is discarded. If however the first transfer does contain an error, the second transfer is used to update the on-board memory provided it has no transmission errors. If errors are detected in both transfers, the transfers will not be used and the data is completely PQMII-T20 removed from the network. The Bad Data bit (Bit 01 of the LCSR) will be set if an error is detected in either transfer. Redundant transfer mode greatly reduces the chance that any data is dropped from the network. However, the redundant transfer mode also reduces the effective network transfer rates. The single Lword PQMII-T20 transfer rate drops from the non-redundant rate of 43 Mbyte/sec. to approximately 20 Mbytes/sec. The 16 Lword (64 byte) transfer rate drops from the non-redundant rate of 174 Mbyte/sec. to the redundaA rogue packet is a packet that does not belong to any node on the network. Recalling the basic operation of Reflective Memory, one node originates a packet on the network in response to a memory write from the host. The packet is transferred around the network to all nodes until it returns to the originating node. It is then a requirement of the originating node to PQMII-T20 remove the packet from the network. If, however, the packet somehow gets altered as it passes through another node or if the originating node begins to malfunction
