PROFIBUS DP-V1 uses the general alarm and event handling provided with the
system. Alarms and events are generated only via the status interface. The
CI854/CI854A influences the generation of alarms/events by setting/resetting the
individual status bits. For every status bit in ErrorsAndWarnings and
ExtendedStatus a fixed configuration information is available that defines if a
change of a status bit shall generate an alarm or event. The generated alarms/events
are of the type system alarm or system event. With the generation of the alarm/event
the status interface also adds the severity and the time stamp.
Hot Swap
The CI854A supports hot swap. It can be replaced online, without any disturbance
to other units connected to the CEX-Bus. After hot removal and the subsequently
insertion the unit gets configured automatically.
In a redundant configuration, the backup unit can be replaced without any
disturbances to the primary unit. This includes that the unit can be replaced online if
it becomes faulty.
For support of hot swap no configuration is necessary.
Hot Configuration in Run (HCIR)
With hot configuration in run a slave can be configured online without initialization
the PROFIBUS communication. The new or changed configuration is downloaded
to the slave while the cyclic communication keeps active.
If a slave supports HCIR I/O-units can be added or deleted online. During
reconfiguration the cyclic data transmission between CI854/CI854A and the slave is
stopped. The CI854/CI854A keeps the input values and the slave the output values.
After finishing the reconfiguration the cyclic data transmission will proceed based
on the new configuration data.
