Siemens SIMATIC RF310M Function Manual page 27

On a connected host PC we start a RF-MANAGER runtime with an RFxxxM device
configured as follows. Notice that the reader type and the application mode have to be set
accordingly.
Figure 2-9
As a side node, please bear in mind to set the network address for your runtime under
'Device Settings, RFID/Network Settings'. This is needed as a 'callback' so that your RFxxxM
devices is able to pass read tag data on to the RF-MANAGER runtime.
Figure 2-10
When starting up our application on the RFxxxM and the RF-MANAGER runtime on the host
PC our AlarmHandler is called three times. Fine!
Wait: Did you say three times?
Ok, when the RF-MANAGER configuration is transmitted to the RFxxxM device there will be
the start reconfiguration event, which is signaled by the Boolean RfAlarmArgs member
IsConfigStart as well.
And when reconfiguration is finished there will be another event containing a list of changed
configuration items, which we deal with in a minute.
But what is the third time we are called? Just keep in mind the initial startup event that is
created in all cases telling you if it was an initial startup or a reconnect and whether there is
configuration data available.
