● Primary server in the RUN state: Primary server is active, that is, life check,
time synchronization and replication of global objects
● Backup server in RUN state: The backup server is active, that is, time
synchronization and replication of global objects by primary server. The
backup server does not accept changes of global objects by a client.
● I/O scan not active
● Communication with XWP not active
● BACnet communication not active
● Wiring test not possible
● D-MAP program processing stopped
Transitions
Power failure
Power restoration. Operating state before power failure was STOP.
Actions (cold start response):
● Cold start I/O scan: Default values for output modules
● Cold-start variable function blocks: Volatile variables are initialized with
initial value. Non-volatile variables retain their last value.
The STOP state is reached when the I/O scan is finished.
Power restoration. Operational status before power failure was RUN.
Actions (cold start response):
● Cold start I/O scan: Default values for output modules
● Cold-start variable function blocks: Volatile variables are initialized with
initial value. Non-volatile variables retain their last value.
● System event: Power restoration.
D-MAP processing starts when the first I/O scan is finished.
Explicit command via dialog in XWP or BACnet (DeviceObject, Out of service
property [OoServ])
Actions (warm start action):
● Implicit warm start I/O scan: I/O scan continues to run
● Implicit warm-start variables function blocks: All variables retain their last
value
● System event: Change to operating state
D-MAP processing starts.
Explicit command via dialog in XWP or BACnet (DeviceObject, Out of service
property [OoServ])
Actions:
● System Event: Change to operating state
● Stop D-MAP processing at the end of current cycle
I/O scan continues.
Restart of the automation station due to software error.
