System bus CAN on board
The controller features an integrated CANopen system bus interface to exchange process
data and parameter values between different nodes and to connect further modules as
e.g. distributed terminals, operator and input devices (”HMIs”) and external control units.
Further information can be obtained from the Communication Manual.

24 V supply
The supply voltage for the control electronics should be fed by a mains-independent 24 V
source. Thus, the control functions remain active even after power is removed.
As an option, the controller can generate the supply voltage for the control electronics
from the DC-bus voltage. Then, the control functions will not be active when power is
removed.
