7 Data transfer
Via the system bus interface, for instance process data and parameter values can be exchanged
between the nodes. In addition, the interface enables the connection of additional modules such as
distributed terminals, keypads and input devices or external control systems and hosts (masters).
The system bus interface transfers CAN objects following the CANopen communication profile (CiA
DS301, version 4.02) developed by the umbrella organisation of CiA (CAN in Automation) in
conformity with the CAL (CAN Application Layer).
