8.3 Determining the boot−up master for the drive system
If the bus initialisation and the related state change from "Pre−Operational" to
"Operational" is not carried out by a higher−level host system (PLC), another node can be
determined as boot−up master to carry out this task.
The master functionality is only required for the initialisation phase of the drive system.
C0356 serves to set a boot up time for the master for the initialisation phase (
^ 90).
By means of the NMT telegram start_remote_node (broadcast telegram) all nodes are
shifted to the NMT−state "Operational" by the master. A data exchange via the process
data objects can only be effected in this state.
The configuration is carried out via C0352.

Note: After the setting, a reset node is required.

Save changes with C0003 = 1.
The settings are only accepted after carrying out one of the following actions:
ƒ Renewed switch−on of the 24 V low−voltage supply
ƒ Reset node via the bus system (by the network management (NMT))
ƒ Reset node with C0358 = 1

Note!
If reset node is executed via GDC, communication will be interrupted. You
therefore have to log in again manually or find the devices connected to the
bus once again (fieldbus scan).
