This code can be used to change the master state.
Note: The parameter should only be set to analyse start problems (e.g. master/bus does not reach the Operational
state). Setting this parameter only sets the state of the master stack. All other nodes remain in their previous states.
Changing the master state via this code may result in an unstable system state.
• A higher bus state than the one initiated by the PLC can never be reached.
• A reload of the master configuration cannot be initiated.
• Loading the PLC program normally stops the bus and sets it to the Pre-Operational state. If this is not possible,
the bus remains in the Unknown or Initialisation state.
• Starting the PLC program normally sets the bus to the Operational state. If this is not possible, the bus remains
in the Pre-Operational or Safe Operational state.

The state is usually requested by the PLC. For possible requested states see
.
• Value "0": Master is not in the requested state.
• Value "1": Master is in the requested state.
