RP 1210<\/h2>\n\n

Brief introduction to RP1210<\/strong><\/p>\n\n

RP 1210 is a proven programming interface initiated through the “Recommended Engineering and Maintenance Practice” of the Technology & Maintenance Council (TMC<\/a>) and the American Trucking Associations (ATA)<\/a>. This interface primarily enables access to vehicle communication interfaces (VCIs) in the truck sector. RP 1210 allows access to J1708\/J1587, CAN, J1939, and J1850 bus systems. Key use cases include programming, diagnostics, and analysis. Much like SAE J2534, the diagnostic interface can be used independently of the OEM\u2014a clear advantage for workshops. <\/p>\n\n

Overview<\/h3>\n\n

The following diagram shows a simplified workflow of how an application uses RP1210:<\/p>\n\n

RP1210_SendMessage transfers a byte buffer to the RP1210 library. The application is responsible for ensuring that the buffer content is in the format appropriate for the protocol. For ISO15765, for example, the format is as follows:1 byte (Message Type) + 4 bytes (CAN ID) + 1 byte (Extended Address) + (0\u20134096) message bytes RP1210_ReadMessage<\/strong> returns a byte buffer, the format of which depends on the protocol. For ISO15765, the following information is added to the beginning of the buffer in addition to the format described above:4 bytes (time stamp) + 0\/1 (echo) + 1 byte (indication status) Echo<\/strong>: when enabled, indicates whether the client originally sent the message. If echo mode is disabled, this byte is not present. Indication Status<\/strong>: Message acknowledged, error occurred, first message of a segment (first frame of a multi-frame message).<\/p>\n\n

The API offers the following functions:<\/p>\n\n

Function<\/th>Description<\/th><\/tr><\/thead>
RP1210_ClientConnect<\/td>Establishing a logical connection to the RP 1210 DLL.<\/td><\/tr>
RP1210_ClientDisconnect<\/td>Terminating the logical connection to the RP 1210 DLL.<\/td><\/tr>
RP1210_SendMessage<\/td>Sends a message to the RP 1210 DLL.<\/td><\/tr>
RP1210_ReadMessage<\/td>Reads a message from the RP 1210 DLL.<\/td><\/tr>
RP1210_SendCommand<\/td>Sends a command to the RP 1210 DLL.<\/td><\/tr>
RP1210_GetErrorMsg<\/td>Translates an RP 1210 error code into text.<\/td><\/tr>
RP1210_GetLastErrorMsg<\/td>Translates an RP 1210 error code into a more detailed text.<\/td><\/tr>
RP1210_GetHardwareStatus<\/td>Returns the connection status.<\/td><\/tr>
RP1210_ReadVersion<\/td>Reads the version information of the RP 1210 API DLL via the API.<\/td><\/tr>
RP1210_ReadDetailedVersion<\/td>Reads the version information of the RP 1210 API DLL via the API (new preferred version).<\/td><\/tr>
RP1210_Ioctl<\/td>Used to change the status of vehicle communication. This was introduced in RP1210B and is currently used by RP1210 only for ISO9141 and KWP2000 communication. This function enables the future development of RP1210 to support additional automotive protocols. <\/td><\/tr><\/tbody><\/table>
