1 Introduction


1.1 Functions

HAT 1400 is a single turn angle sensor for the determination of the absolute angle within a range of 0 to 360°.

 Measuring the current turning angle using:

-

1kHz sample rate

-

Accuracy 0.1 % typ.

- bit

 Conversion of the angle value into a user-scaleable linear process value.

 Sending the current process value:

-

Cyclically, within the range from 1 millisecond to 1 minute

1.2 Interfaces

HAT has a CAN 2.0 B interface and can be operated according to the process defined in the standards SAE-J1939. The interface functions are divided into 3 parts:

 Address Claiming

 Configuration

 Sending process values

2 Address Claiming

2.1 General overview

Each HAT has a name and an address. Both can be configured by the user. The name of the HAT is a 64 bit value and is clearly recognisable worldwide, the address is a 8 bit value which must be clearly recognisable at the bus. This means, it is not allowed to have two devices with the same address connected to the same bus.

During Address Claiming the HAT communicates its address and name to the other bus participants. This is a reaction to eventual address conflicts.

2.2 Name

The name consists of the following parts:

 1 Bit Arbitrary Address Capable

2.2.2 Function specific sections

The function specific sections are configurable.

 3 Bit Industrial Group (i.e. Global, Marine, Agriculture, ...)

 7 Bit Vehicle System (depends on Industrial Group: Tractor, trailer, …)

 4 Bit Vehicle System Instance (sequence number for systems of the same kind)

 8 Bit Function (depending on Industrial Group: i.e. System Display, Levelling System, …)

 5 Bit Function Instance (sequence number for functions of the same kind)

 3 Bit ECU-Instance (sequence number for controllers having the same function)



2.2.3 Manufacturer specific sections

 11 Bit Manufacturer Code

 21 Bit Idendity

The function-related parts are configurable, the manufacturer-related parts are firmly defined. This ensures a worldwide clear address identification.

5

2.3 Address

The address can be set between 1 and 253. The address 254 is reserved for the status "no address assigned", the value 255 is used as broadcast address.

In each message the HAT sends, the address is assigned to the lowest 8 bits of the message ID. The pre-defined address is 1 see chapter 3.2 „Complete list of settings (Object

List

"OL")

“ OL-Index 1.

2.4 Start-up process

After each start-up, the HAT sends an "Address Claimed" message (i.e.: 0x18EEFF01

[<name>]).. Thus, it communicates its address and its name to the other participants. This message can also be requested by other participants using a "request" message.

If an other participant sends an "Address Claimed" message using the same address, the reaction of the HAT depends on the name of the other participant. If the HAT has a name with a higher priority, it again sends an "Address Claimed" message. If the HAT sends a higher address, it sends a "Cannot Claim" message and will then no more be available. In order to carry out a device reset, HAT must be briefly disconnected from the supply voltage.

After sending an "Address Claimed" message, it takes 250 ms until the HAT takes up its regular operation mode. This is one of the requirements of SAE-J1939 to give other devices having the same address enough time to respond.

E

HAT is a "Service Configurable Device". This means, the address is adjustable, but the HAT cannot be assigned a new address in normal bus mode. Going through a configuration process, HAT must be assigned a clearly defined address for its later bus, before it is getting connected to the bus for normal operation. The configuration process is described in the next chapter.

If 3 devices having the same address are connected to the bus, two of them will always send a "Cannot Claim" message which is sent out at the same time in the worst case. This can lead to a bus error. For this reason, the user must make sure that the address at the bus is clearly defined.


6 Protocol description SAE J1939 HAT 1400

3 Configuration

The HAT has different settings which can be read and written by a master using SAE-J1939 messages. This is carried out by means of a so-called proprietary parameter group A with the PGN 61184 (0x00EF00). The data then contain information on which settings must be read or written and information on the values themselves as well.

All settings are managed in an object list OL (similar to CANopen). All configuration objects in this list have a clear index, by means of which they can be addressed individually. Some of the objecs represent device settings which can also be changed by the operator. In the table described in the following, all the objects or settings with their corresponding index are listed. The object access can only be defined as "read only" (ro) or "read and write" (rw).

Objects representing the device settings are generally changeable (rw).

The device configuration process will be defined in detail in chap 4 "Carry out configuration"

E

3.1 Short description of the configuration message

The configuration message serves to read or write entries in the object list. Here, the data range of the configuration message (PGN 61184) is subdivided as follows:

Index r/w dc ack Value

(Byte 1) (Byte 2) (Byte 3) (Byte 4) (Byte 5) (Byte 6) (Byte 7) (Byte 8)

Name Byte Content

Index 1 Index of the object in the object list "OL" r/w 2 Read or write access, 0=read, 1=write dc ack

3

4

"Don’t care", always 0

Acknowledge code, see table 4.1.4 description of "Acknowledge

Code"

Value 5-8 Used data, "Little Endian" format

The user data range "Value" of the configuration message will be defined using the data type of the OL (object list). The data type defines the number of used data bytes. The number is represented in "Little-Endian" which means the least significant data byte (LSB) will be located at the lowest address (byte 5).

In a uint16 value, for example, only the first two bytes (byte 5 and byte 6) of the value range of the configuration message are used and interpreted as unsigned 16 bit integer value.

3.3 Process value transmission

The following tables describe how the process values (measured values) are transmitted as groups within a PGN. The specific PGN for the group is defined via the OL (Object List), see for example chapter 3.2.4 Process value transmission, OL Index 23 and 24.

The used data format is "Little-Endian", which means the least significant data byte will be located at the lowest data block byte address.

3.4 Process value visualisation

The process or measured value sent via SAE J1939, is always positive

(0..0xFFFFFFFD). If the factory-set upper or lower measuring range is negative, an offset must be set in order to enable sending of the measured value.

The values 0xFFFF and 0xFFFE are reserved for SAE J1939. This means, the measured value at the lower measuring range limit must be greater than or equal to 0 and the value at the upper measuring range limit must be lower than or equal to 4294967293. If the value 0xFFFE is sent, this means "Error" according to SAE J1939 and the device mode and the device status will be set accordingly.



3.5.2 Send process values (on request)

11

The device sends its process values (measured values) on request via a request message

(PGN 59904 (0x00EA00)) by means of the PGN which has been set in the user setup

(Object List).

4 Carry out configuration

To read or write the settings, the master sends a message with the PGN 61184 (0x00EF00) to the HAT's address. HAT responds by the same PGN (parameter group number) and sends an acknowledge code.

In case of reading requests the requested data are written into the value range of the response.

Procedure for the permanent change of settings must be strictly adhered to:







„Start editing mode“, see commands chap. 4.3.1

 Reading and writing of the desired Object List Entries

"Saving the settings", see commands chap. 4.3.2

"Restart", see commands chap. 4.3.4

Please note:

The reading of entries from the Object List (OL) can be carried out directly.

4.1 The design of the configuration message is PGN 61184 (0x00EF00) .

HAT uses the PGN 61184 „Proprietary A“ for the configuration of the device settings. This special PGN is intended for the customised communication according to SAE J1939-21.

The PGN is part of the specific parameter groups which means the "PDU Specific" part of the PGN contains the address of the target device, in our case the device address of the

HAT.

Commands are a special function with the configuration They are handled via the PGN

61184 as well. In contrast to the general entries in the Object List (OL), writing on a control command index triggers a function in the device.

E

4.3.1 Start editing mode

Before the settings are written, the master must set the HAT to an editing mode. This is carried out by writing the string "edit" into the Index 101. In the editing mode, HAT reacts exclusively to configuration commands. In the editing mode no measured values can be sent. The editing mode therefore always has to be finished by a restart.

Prior to restarting, the changes must be explicitly saved (Index 102). If restart is carried out without saving, all changes will be lost!
