3.1.2 Bus Node
The task of the Cube67 System is to combine decentrally the signals of the I/O level and provide this
information over the field bus network (e.g. PROFIBUS). The central unit is the bus node, which
interconnects the Cube67 I/O modules and the field bus.
The bus node is powered via a 7/8“ power cable.
The bus node also has four connections for the internal system connection with connectivity for up to
four I/O modules. In this way, it is possible to connect up to 16 I/O modules to one bus node.
Table 3-1 : Bus nodes
It is possible to connect up to 16 I/O modules to one bus node. Up to four I/O modules
can be attached to each terminal of the internal system connection.
3.1.3 I/O Modules
These modules are connected to the bus node via the internal system connection. I/O modules can be
either compact or expander units.
3.1.4 Compact Modules
A compact module has no extension interface for the internal system connection; consequently it is the
only, or the last module in a branch of the internal system connection.
The DIO 16 C 8xM12 also has a connection for an external actuator supply.
