if (alarmArgs.IsConfigStart)
{
// Reconfiguration has started
// => disable UI
}
else if (alarmArgs.InfoItems != null)
{
// Reconfiguration has finished
if (alarmArgs.InfoItems[0].Name == "Reconfiguration" &&
alarmArgs.InfoItems[0].Value == "Initial")
{
// This is the very first startup of the application
// where no configuration data is available
}
else if (alarmArgs.InfoItems[0].Name == "Reconfiguration"
&& alarmArgs.InfoItems[0].Value == "Reconnect")
{
// The reader service was already running and we
// only reconnected => reinitialize, e.g by rereading
// configuration data
}
else
{
// A configuration was received from RF-MANAGER and
// has been activated.
// => The list of RfInfoItems contains the changed
// configuration items
}
