Fuel Dispensers TATSUNO EUROPE ‐ Installation and User Manual , revision 10, January 2022
4.1.10. DISPLAYING THE PROGRAM VERSION AND CHECK SUMS (P05)
This function shows the number of the program version of the dispenser counter and
different check sums. These values are intended for metrology authorities and
authorized service engineers. The meaning of the individual parameters is described in
the table below.
Parameter
Meaning
P05‐1
Version of the metrologically relevant part of the program. It is specified in the type certificate (e.g., 102 = version V1.02)
P05‐2
CRC (check sum) of metrologically relevant part of the program. It is specified in the type certificate (e.g., dbd2 FFA4)
P05‐3
Version and release of the whole program (e.g., 1.02 release 14)
P05‐4
CRC (check sum) of the whole program (e.g., 27E6 622d)
P05‐5
CRC (check sum) of the temperature sensors unit PDEINP1 program (for temp. sensors 1 to 4). If not present „ ‐ ‐ ‐ ‐ " is displayed
P05‐6
CRC (check sum) of the temperature sensors unit PDEINP1 program (for temp. sensors 5 to 8). If not present „ ‐ ‐ ‐ ‐ " is displayed
P05‐7
Date and time the program compilation. The first line shows the time (hhmmss) and the second the date (DDMMYY).
P05‐8
CRC of the program of the pressure sensors unit PDEDPS with address 1. If not present, "‐ ‐ ‐ ‐" is displayed
P05‐9
CRC of the program of the pressure sensors unit PDEDPS with address 2. If not present, "‐ ‐ ‐ ‐" is displayed
P05‐10
CRC of the program of the pressure sensors unit PDEDPS with address 3. If not present, "‐ ‐ ‐ ‐" is displayed
P05‐11
CRC of the program of the pressure sensors unit PDEDPS with address 4. If not present, "‐ ‐ ‐ ‐" is displayed
NOTE
Metrologically relevant data P05‐1 and P05‐2 also appear on the display for a while after the power on.
NOTE
The calculated CRC (cyclic redundancy sum) values from sub‐parameters 1 and 3 are checked after switching
on. If the calculated checksum is different from the stored correct sum, the dispenser is blocked and error message
E13 is displayed. Higher cyclic checksum orders are displayed on the amount line, lower orders on the quantity line.
The CRC of the peripheral unit programs (PDEINP and PDEDPS) is checked before each delivery is enabled. If the
calculated value of the peripheral unit checksum does not match the correct value, delivery (fuelling, pumping) is not
started and the corresponding error message is displayed.
4.1.11. MODBUS INTERFACE ACTIVATION (P06)
The modbus interface (diagnostic data line) allows service organizations to remotely diagnose dispensers.
Parameter P06 allows to activate the Modbus interface by entering a valid key (eight‐digit
code).
Parameter
Meaning
P06=0
The Modbus license is not valid. Modbus interface is not active
P06=1
The Modbus license is valid. Modbus interface is active
4.1.12. MANAGER MODE ACCESS PASSWORD (P08)
This function allows to view and change the password to the manager mode. The setting is made by pressing
the <E> key by entering a new password in <PPPP> format and confirming <E>.
Parameter
Meaning
P08 = 1 to 9999
Manager mode access password
