Overview
EN 15430-1:2007/FprA1 (CEN) defines a standardized protocol for in‑vehicle data acquisition in winter and road service area maintenance equipment. The standard specifies the interface, message format, variables, records and reports used to download data from an equipment control box to an in‑vehicle board computer. Its primary goal is to ensure interchangeability between a vehicle and different implements (spreaders, sprayers, etc.) so that one vehicle can carry and communicate with many equipment types reliably.
Key topics and technical requirements
- Message structure and framing: Records are text lines terminated by CR+LF and framed with SOH (start) and EOT (end) control bytes to avoid synchronization issues.
- Handshaking: Receiver validates CRC and replies with single-character ACK or NAK. Sender retries a failed message up to two times; lack of handshaking is supported for legacy devices (no ACK/NAK).
- Data integrity:
- CRC-16 (CCITT, polynomial 0x1021, init 0xFFFF) used for record validation.
- CRC-32 (CCITT polynomial specified in the amendment) available for stronger integrity checks.
- Two-level integrity model introduced: CRC_REC (CRC over a record) and CRC_STREAM (rolling CRC including previous CRC_STREAM) to detect manipulation and deletion of data.
- Time synchronization: A Time Sync record (sent first and periodically) lets the receiver compute clock offsets and align data from multiple equipment sources; board computers must maintain a real time clock.
- Numeric and encoding rules: Numerical values are transmitted as ASCII decimal; CRC values are ASCII hexadecimal uppercase.
- Variable and record definitions: Standardized list of variables (Version, SysTime, SysDate, Source, ManufID, EquipID, DriverID, RunHrs, BeaconOn, device identifiers, free definable fields) and specific spreader/sprayer fields (mode, width, dosage, material codes, brine %, simulation speed).
- Error and data‑loss handling: Causes such as no handshaking, buffer overflow or repeated retransmission failures are identified and guidance given (e.g., user notification, synchronization practices).
Practical applications
- Ensure interoperability between vehicles and different winter maintenance implements (spreaders, sprayers, combi units).
- Support fleet data logging for audit, compliance, billing and performance analysis (e.g., material usage, treatment coverage).
- Enable real‑time monitoring and post‑event reporting in municipal winter services and road maintenance operations.
- Provide a standard integration layer for board computer software, office reporting systems and telematics providers.
Who should use this standard
- Vehicle manufacturers and upfitters integrating multiple implements.
- Equipment suppliers (spreader/sprayer control systems) implementing data transmission handlers.
- Fleet managers, municipal road authorities and contractors requiring standardized data capture and reporting.
- System integrators and software developers building board‑computer or back‑office applications for winter maintenance.

2 Modification to Clause 3, Terms and abbreviations
Add the following abbreviation under CRC-16 reference:
"CRC-32 Cyclic Redundancy Code with 32 bits".
3 Modification to 4.2.3, Communication protocol
Delete the existing text in 4.2.3 until Figure 3 and replace it with the following:
"Transmission of a record.
In this definition a message to be communicated consists of one record. Records are terminated by CR+LF (a
record is one line of text). In general, a message is sent by the sender (e.g. the “Data transmission handler” of
a spreader) and received by the receiver (e.g. the Board-computer). After power up, communication is always
started by the vehicle/equipment “Data transmission handler” sending its first message (this is the time
synchronisation record). Refer to Figure 4 for flow charts of the sender and receiver algorithms.
The receiver will check the validity of a message by testing if the CRC-16 value corresponds to the data in the
message received. If the data is valid, the receiver sends an ACK. The sender can now send a new message.
If the data is invalid, the receiver sends a NAK. Then, the sender will try to send the same message again for
a maximum of 2 times. If the message still fails, the message is considered to be lost. Preferably, a notification
is given to the user (operator) that data has been lost by the sender and/or the receiver.
Remark: The receiver sends an ACK or a NAK as a single character without other data. The ACK or NAK
refers to the latest message sent by the sender. To avoid record synchronisation problems between sender
and receiver, the sender must ignore any ACK or NAK received during the transmission of a message until the
last byte is sent (EOT character). Also, the receiver is not allowed to send an ACK or NAK during the
reception of a message until the last byte is received (EOT character).
Remark: Numerical values have to be transmitted with ASCII characters in decimal code.
Calculation of the CRC-16 value.
The CRC value is calculated according to the CCITT definition. The CRC value is calculated over all record
16 12 5 0
bytes, starting with the record code, ending with CR+LF. The polynomial used is x + x + x + x = 11021
h
(i.e. XOR mask 1021 ) and initial value FFFF .
h h
Remark: The value is written in ASCII characters in hexadecimal code with capitals (0.9,A.F).
Calculation of the CRC-32 value.
The CRC-32 value is calculated according to the CCITT definition. The CRC-32 value is calculated over all
record bytes, starting with the record code, ending with CR+LF. The polynomial used is
32 26 23 22 16 12 11 10 8 7 5 4 2
x + x + x + x + x + x + x + x + x + x + x + x + x + x + 1
Remark: The value is written in ASCII characters in hexadecimal code with capitals (0.9,A.F).
Sender without receiving options for handshaking.
For old vehicle/equipment “Data transmission handlers”, it may be impossible to receive data. In this case the
sender cannot respond to an ACK or NAK, i.e. there is no handshaking feature. Hence, the sender will send a
new message. This may cause in the result that data gets lost, e.g. in case the Board-computer was not
started up yet or if transmission failed. It is up to the user to handle this problem (for example to connect
power supply such that power-up is always at the same time for sender and transmitter).
Synchronisation of communication.
To synchronise communication between sender and receiver, a message always starts with an SOH and ends
with an EOT. If the receiver is not synchronised yet but the sender is already transmitting a message (e.g.
when the Board-computer starts up while the spreader “Data transmission handler” is sending), all data before
the first SOH will be ignored. If the receiver is synchronised but detects an SOH before an EOT, the previous,
unfinished message is ignored.
Time synchronisation between sender and receiver.
In general, the sender system time and the receiver system time are not equal. To synchronise messages to
the system clock of the receiver, a time synchronisation record is introduced. This Time Sync record (refer to
5.5.1) contains the actual system time of the sender at the start of record transmission (with a maximum error
of ± 0,5 s). The receiver must record its system time at the moment of reception of a message. In case of the
reception of a Time Sync record, the receiver can calculate the difference between its own system clock and
the system clock of the sender. Now, the receiver can time-synchronise every message received from the
sender and thereby synchronise this data to other data generated by other sources. The board computer must
contain a real time clock which runs even if the board computer has no power. The electronic system on the
vehicle/equipment must have a real time clock which runs even when this system has no power, or, a
software clock must be implemented made which starts at date 1-1-2000 and time 00:00:00 and is updated
every second.
A Time Sync record, is sent by the sender:
as the first message starting the communication;
after 10 s if the receiver does not respond to a message with an ACK or a NAK; after a successful
transmission of this record, the latest message before the time synchronisation record is transmitted
again;
if the system clock of the sender is adjusted, reset or set to any value which would cause a jump in
time.
Loss of data.
Data will get lost in case of:
a “Data transmission handler” without handshaking feature which is sending while
