Configuration Service selection

The LIN Configurator supports eight configuration service requests (0xB0 to 0xB7) to select for automatic handling:

  • Service 0xB0

    – "Assign NAD" – An optional service per LIN 2.2 and ISO17987 specifications. This is a service request where a new NAD value is assigned to the slave node.

  • Service 0xB1

    – Assign frame identifier" – An obsolete service per LIN 2.2 and ISO 17987 specifications. It is available only if the LIN 2.0 Compatibility checkbox is selected on the

    General

    subtab.

  • Service 0xB2

    – "Read by identifier" – This service is mandatory per LIN 2.2 and ISO 17987 specifications. This request is used to allow the LIN master to read the slave's identification information (Supplier ID, Function ID, and Variant). This middleware only supports the LIN Product Identification version of this request.

  • Service 0xB3

    – "Conditional change NAD" – An optional service per LIN 2.2 specifications. Also, this is an optional obsolete service in the ISO 17987-3 specification.

  • Service 0xB4

    – "Data dump" – This service is optional per LIN 2.2 and ISO 17987 specifications and is not supported by this middleware.

  • Service 0xB5

    – "Assign NAD via SNPD" – This service is not supported per LIN 2.2, and ISO 17987 specifications. However, when the Enable J2602-1 Compliance checkbox is selected on the

    General

    subtab, this service’s meaning changes to "Targeted Reset", which is supported by this middleware.

  • Service 0xB6

    – "Save configuration" – An optional service request per LIN 2.2 and 17987 specifications.

  • Service 0xB7

    – "Assign frame identifier range" – A mandatory configuration service per LIN 2.2 and ISO 17987-3 specifications. This service allows the LIN master to change the volatile frame PID values for the slave’s frames.

Slave information

If the user selects the Automatic Configuration Request Handling option, three fields become available to enter values used in the configuration service requests. These fields are as follows:

  • Supplier ID

    – This is a 16-bit value, but its valid range is from 0x0000 to 0x7FFE.

    Note:

    The supplier ID default value is 0x00C3.

  • Function ID

    – This is 16-bit value, and its valid range is 0x0000 to 0xFFFE.

  • Variant

    – This is 8 bit-value and its valid range is from 0x00 to 0xFF.

Automatic Configuration Request Handling​

All the other options on the subtab are available only if the Automatic Configuration Request Handling option is selected. Deselect this option to handle these requests with your own custom application code. Whenever any automatically-handled request occurs during the LIN bus operation, the corresponding MRF and SRF frames will not be available to the application through the Transport Layer API. If this option is not selected on this subtab, then the corresponding MRF and SRF frames of the configuration service request are received or sent by the application using the Transport Layer API.
