Description

VARAN is a hard real time Ethernet based industrial network, which uses master/slave communication where only one master is allowed in the network. The manager (master device) sees the whole network as a 4GB RAM, from which every client (slave device) gets its 64 KB address space. The manager administers the network, provides automatic clients addressing and indicates if any kind of failure has happened. From the network user’s point of view, sending and receiving data packets is brought to simple write/read operations from the desired client’s address.

In order to provide easy bus topology realization, a client device might have a splitter-out port, besides the network-in port.
