Master Functionality; Control Boot-Up Sequence, Network Management - BONFIGLIOLI Vectron ACTIVE Manual

4.8
An external control or an frequency inverter defined as a master (node ID = 0) can be
used as a master. The fundamental tasks of the master are controlling the start of the
network (boot-up sequence), generating the SYNC telegram and evaluating the emer-
gency messages of the slaves.
Further, there can be access to the parameterization of all the frequency inverters on
the system bus by means of a field bus connection via the client SDO of the master
frequency inverter.
4.8.1
The Minimum Capability Boot-Up method defined according to CANopen is used for
the state control of the nodes (nodes).
This method knows the pre-operational, operational and stopped states.
After the initialization phase, all the nodes are in the pre-operational state. The system
bus master transmits the NMT command Start-Remote-Node. With this command,
individual nodes or all the nodes can be started together. An frequency inverter de-
fined as a master starts all the nodes with one command. After receipt of the Start
Remote Node command, the nodes change into the Operational state. From this time
on, process data exchange via the PDO channels is activated.
A master in the form of a PLC/PC can start the nodes on the system bus individually
and also stop them again.
As the slaves on the system bus need different lengths of time to conclude their ini-
tialization phases (especially if external components exist alongside the frequency
inverters), an adjustable delay for the change to Operational is necessary. The setting
is done in an frequency inverter defined as a system bus master via
904.

Start-Remote-Node is cyclically transmitted with the set delay time by an
frequency inverter defined as a system bus master, in order to put slaves
added with a delay or temporarily separated from the network back into
the Operational state.
