2.3.4 Generic Data Mode
In this mode, there is no master-slave relationship between the nodes on the sub-network and the gate-
way. Any node (including the gateway) may spontaneously produce or consume a message. Nodes are
not obliged to respond to messages, nor do they need to wait for a query in order to send a message.
In the figure above, the Anybus Communicator ‘consumes’ data ‘produced’ by a node on the sub-net-
work. This ‘consumed’ data can then be accessed from the higher level network. This also works the
other way around; the data received from the higher level network is used to ‘produce’ a message on the
sub-network, for ‘consumtion’ by a node.
