uds.message.service_identifiers

Service Identifier (SID) data parameter implementation.

Note

Service Identifiers values and their meanings are defined by ISO 14229-1 and SAE J1979 standards.

Module Contents

Classes

RequestSID	Request Service Identifier values.
ResponseSID	Response Service Identifier values.

Attributes

ALL_REQUEST_SIDS	Set with all possible values of Request SID data parameter according to SAE J1979 and ISO 14229 standards.
ALL_RESPONSE_SIDS	Set with all possible values of Response SID data parameter according to SAE J1979 and ISO 14229 standards.

uds.message.service_identifiers.ALL_REQUEST_SIDS: uds.utilities.RawBytesSetAlias

Set with all possible values of Request SID data parameter according to SAE J1979 and ISO 14229 standards.

uds.message.service_identifiers.ALL_RESPONSE_SIDS: uds.utilities.RawBytesSetAlias

Set with all possible values of Response SID data parameter according to SAE J1979 and ISO 14229 standards.

exception uds.message.service_identifiers.UnrecognizedSIDWarning

Bases: Warning

Warning about SID value that is legit but not recognized by the package.

Note

If you want to register a SID value, you need to define members (for this SID) manually using add_member() method (on RequestSID and ResponseSID classes).

You can also create feature request in the UDS project issues management system to register a SID value (for which this warning was raised).

Initialize self. See help(type(self)) for accurate signature.

class uds.message.service_identifiers.RequestSID

Bases: uds.utilities.ByteEnum, uds.utilities.ValidatedEnum, uds.utilities.ExtendableEnum

Request Service Identifier values.

Note

Request SID is always the first payload byte of all request message.

Initialize self. See help(type(self)) for accurate signature.

classmethod is_request_sid(value)

Check whether given value is Service Identifier (SID).

Parameters:

value (int) – Value to check.

Returns:

True if value is valid SID, else False.

Return type:

bool

class uds.message.service_identifiers.ResponseSID

Bases: uds.utilities.ByteEnum, uds.utilities.ValidatedEnum, uds.utilities.ExtendableEnum

Response Service Identifier values.

Note

Response SID is always the first payload byte of all request message.

Warning

This enum contains multiple members (for all the services as RequestSID), but most of them are dynamically (implicitly) added and invisible in the documentation.

Initialize self. See help(type(self)) for accurate signature.

classmethod is_response_sid(value)

Check whether given value is Response Service Identifier (RSID).

Parameters:

value (int) – Value to check.

Returns:

True if value is valid RSID, else False.

Return type:

bool
