11.7 Communication phases/network management
Regarding communication via the system bus, the controller distinguishes between the following
statuses:

Tip!
Part of the initialisation or the entire initialisation can be carried out anew in every status
by transferring the corresponding network management telegrams.
The current CAN status is displayed in
C00359 for diagnostic purposes.
Status Explanation
"Initialisation"
(Initialisation)
After switch-on, an initialisation run is carried out.
• During this phase, the controller is not involved in the data exchange via
the bus.
• The standard values are re-written to all CAN-relevant parameters.
• After initialisation is completed, the controller is automatically set to the
"Pre-Operational" status.
"Pre-Operational"
(before being ready for operation)
Parameter data can be received, process data are ignored.
"Operational"
(ready for operation)
Parameter data and process data can be received!
"Stopped"
(stopped)
Only network management telegrams can be received.
