Information about the status of up to two sensors and the initiator of the
message.
The second sensor is not implemented yet.
For special applications, the reading process of the RFID reader is triggered
by two sensors. In this case it is necessary to distinguish between the two
sensors. The initiator represents the number of the sensor that has caused
the message.
Default: Only sensor 0 is defined.
Sensor 0:
bit 0 - bit 2
The current status of sensor 0 is described in three bits.
0
Sensor not occupied
1
Sensor occupied
7
Sensor not defined
Sensor 1:
bit 3 - bit 5 (defined for future developments)
The current status of sensor 1 is described in three bits.
0
Sensor not occupied

Initiator:
bit 6 - bit 7
The initiator represents the number of the sensor that has caused the
message.
