FAQ
Q: What are the absolute maximum ratings for the MAIN RFID
Architecture (CEB-A)?
A: The power supply (logic) should not exceed 30 Vdc, and
digital inputs (24Vdc) should stay below 28.8 Vdc.
Q: What are the electrical characteristics of the MAIN RFID
Architecture (CEB-A)?
A: The supply voltage ranges from 19.2 to 28.8 Vdc with a
typical supply current of 50 to 80 mA when all digital outputs are
turned off. Digital inputs have turn-on voltages between 14.85 to
16.2 V, turn-off voltages between 11.8 to 13.5 V, and a switching
frequency of up to 500 KHz.

4 Firmware Description
MAIN RFID Architecture (CEB-A)
4.1 State machine operation
4.1.1 Enqueue pallet
As soon as a pallet is recognized from the antenna, its ID is inserted into the queue (4 elements deep), only if it is not already present, and the rfidCnt timer is preset.
4.1.2 Pallet photocell events
The photocell generates events on the rising / falling edges, respectively when a pallet arrive to / depart from the photocell.
4.1.2.1 On the rising edges (a pallet arrives at the photocell)
1. The first ID is picked and removed from the queue.
2. This ID is processed. The value of rfidCnt is compared to determine if the antenna is too close / far.
3. If the pallet takes too much time between the antenna identification and the photocell detection, the next valid ID is processed.
4.1.2.2 On the falling edges (a pallet leave the photocell)
1. If the gate is opened, the time between the rising and falling edges of the photocell
determines the pallet speed.
If the speed is in bounds, the delay used to generate the deviation signal is
calculated using the following formula:
palletDimension palletTime
=
gatePhotocellDistance delay
else one of the following errors is generated : “PALLET_FAST”, “PALLET_SLOW”, “PALLET_TOO_FAST” or “PALLET_TOO_SLOW”.
2. If the pallet is in the action-list, received from the master, the associated action take place:
(a) If the command is “ADD_EMPTY_PALLET”
i. “PASSEMPTY” flag is active (that means you didn’t enable the tube present photocell while the pallet passed) : if the skipCnt counter is expired, the “DIVERTED” message is sent, else the “PALLET_TOO_SLOW” error is sent.

MAIN RFID Architecture (CEB-A) ii. “PASSFULL” flag is active (that means you have activated the tube present
photocell while the pallet passed) : the “TUBE_PRESENT_WHEN_NOT_EXPECTED” error is sent.
(b) If the command is ADD_FULL_PALLET
i. “PASSFULL” flag is active (that means you have activated the tube present photocell while the pallet passed) : if the skipCnt counter is expired, the “DIVERTED” message is sent, else the “PALLET_TOO_SLOW” error is sent.
ii. “PASSEMPTY” flag is active (that means you didn’t enable the tube present photocell while the pallet passed) : the “TUBE_ABSENT_WHEN_NOT_EXPECTED” error is sent.
3. If the pallet is in the action-list but there is no room for the pallet on the destination lane, the “NO_ROOM_TO_DIVERT” error is sent.
4. If the pallet is in the action-list but the node is offline, the “NODE_STATUS_OFFLINE” error is sent.
5. If the pallet is not on the action-list, and there aren’t pending errors, then it is diverted and the “PASSFULL” / “PASSEMPTY” message is sent respectively on presence or absence of the tube on the pallet.
4.1.3 Start motor logic
The startMot signal activation occurs when the counter PulseDelayCnt expires, and remains active for a fixed time of 20 ms. PulseDelayCnt is preset by the deviation delay calculated above.
4.1.4 Photocell tube
The photocell is used to set the flags “PASSFULL” or “PASSEMPTY” according to the presence of the tube. If the tube photocell signal is active but pallet’s one is not, the “UNEXPECTED_TUBE” error is sent only for the first occurrence. From the second onwards the “TOO_MUCH_UNXP_TUBE” error is sent (indicating the eventual photocell light interference).

4.1.5 Gate Management
The gate’s electrovalve is activated when :
1. HomeMot signal = 0 (the motor is performing homing). 2. Receiving “EMERGENCY_GATE_OUT” command. 3. Receiving “HOME_GATE” command.
Deactivated when : 1. HomeMot signal = 1 (the motor isn’t performing homing). 2. Receiving “EMERGENCY_GATE_IN” command.
4.1.6 Engine Management
4.1.6.1 The motor board MSV
When the motor board turns on, it automatically starts the homing procedure (homeMot is set to zero). When this procedure is correctly completed, with the pad aligned to the track the homeMot goes to 1.
4.1.6.2 The RFID board CEB-A
1. When the RFID turns on it sets the state variable homeMotStt to “HM_BOOTUP”.
2. When in “HM_BOOTUP” state, it waits for the homing completion by the motor board through NRZ communication. If within 5 second the homing isn’t performed, then the procedure is requested 4 more times. If the homing isn’t correctly done, the “HOMING_TMO_ALIGNED” or “HOMING_TMO_NOT_ALIGNED” error is sent, according to the pad position, else the state is set to “HM_READY”.
3. In the state “HM_READY” when the signal homeMot goes to zero (meaning a position lost of the pad) the “HOMING_GATE_IN” or “HOMING_GATE_OUT” error is sent according to the gate state. Then it goes into the “HM_WF_TMO” state waiting for homing (homeMot = 1).
4. When in the “HM_WF_TMO” state, if the homing procedure isn’t completed within the time homeMotTmo (5 seconds) the “HOMING_TMO_ALIGNED” or “HOMING_TMO_NOT_ALIGNED” error is sent, according to the pad position. If the homing finish properly it send a null message (all zeroes).
