MVME6100 Decentralized Control System

The core modules of the MVME6100 decentralized control system are encapsulated in robust engineering plastic housings with good heat dissipation. The modules have passed the strict electromagnetic compatibility test, which is in line with the level 3 standard and locally reaches the level 4 standard. It can work stably for a long time in the complex electromagnetic environment. Decentralized control system control network eNet adopts peer-to-peer industrial Ethernet, structured on two physically isolated redundant industrial Ethernet networks, supporting redundant ring or redundant star network topology;

The MVME6100 system supports eight network domains, each of which connects up to 64 pairs of controllers and 64 operating stations, and data transmission between all network nodes does not need to be passed through a server. Data security transmission between network domains is realized through three-layer switches or routers, and the authority and data flow direction of data communication between any network domains can be set. Each network device has two independent and completely isolated network interfaces, the redundant network works simultaneously, the sent data is processed by data filtering and redundancy at the receiving end, if network switching occurs, the switching time is equal to zero, there is no interruption and delay in data application, so there is no problem of network redundancy switching.

The MVME6100 network adopts multicast-based network communication technology. The distributed network management system automatically monitors network changes and manages process data communication, and any eNet network node can be taken offline and online at any time. eNet adopts an active sending mechanism based on the exception report type, which is carried out by the KM950 controller in accordance with the data change situation. No matter how many operator stations there are, the controller only sends data once, which greatly reduces the network load and controller load.
