Parameterising The Controller As Can Master - Lenze L-force HighLine C 8400 Series Reference Manual

10.7.3

Parameterising the controller as CAN master

If the initialisation of the system bus and the associated status change from "Pre-
Operational" to "Operational" is not effected by a superimposed host system, the
controller can instead be defined to be a "quasi" master to execute this task.
The controller is configured as CAN master in C00352.
 Being the CAN master, the controller sets all nodes connected to the bus (broadcast
telegram) to the "Operational" communication status with the "Start remote node"
NMT telegram. Only in this communication status, data can be exchanged via process
data objects.
 A delay time can be set in
the controller transmits the "Start remote node" NMT telegram.

Note!
The changes of the master/slave operation in
• another mains switching of the controller
or
• the "Reset node" or "Reset communication" NMT telegram has been
transmitted to the controller.
The "CAN reset node" device command (C00002/26) is provided as an alternative
to the "Reset node" NMT telegram for the reinitialisation of the CAN-specific
device parameters.

Tip!
Master functionality is only required during the initialisation phase of the drive
system.
