What is theVnet/IP?
Vnet/IP is IEEE802.3 compliant control bus configured with dual-redundant busses. Each dual-redundant bus is configured with a layer 2 switch(*1) with the maximum transmission speed of 1Gps and 1000BASE-T cables and devices in a domain are connected in star connection or tree connection.
Vnet/IP dual-redundant bus 1 is exclusively used for control communication by a various kind of standard protocol based on Ethernet,Bus 2 enables data access by Exaopc OPCinterface and comunications based on TCP/IP protocol.
The Vnet/IP is a real-time process control network used to connect system components. The Vnet/IP supports two types of communictions: control-bus communications and oen communications. The Vnet/IP is always dual-redundant. usually, control bus communications are carried out via bus 1, Open communications are carried out via bus 2.?If a control communications error occurs at the bus-1 side, control bus communications will be carried out via bus 2. The Vnet/IP uses general purpose communications devices for network connection.
