Linear Arcnet, Expanded By Active Distribution Units (Active Hubs) - ABB Advant AC500 Manual

Linear ARCNET, expanded by active distribution units (Active Hubs)

Active Hubs amplify the arriving signals. So they stabilize the network configuration and allow especially
for high distances. The Active Hub decouples the station connectors from each other. Therefore, the
entire network does not fail when one of the connections fails.
The maximum length of the network is 6 km.
A maximum of 255 stations can be used.
