Input

string Name specifies an individual channel within the task defined by reference in. The default (unwired) value of name is empty, which means the property applies to the entire task, not a specific channel. If a property relates to Measurement or Characteristic channels and does not apply to the entire task, but an individual channel or message within the task, you must wire the name of a Measurement or Characteristic channel from channel list into the name input. For other properties you must leave name unwired (empty).
long unsigned integer Reference in is the reference to any opened A2L database, a selected ECU, or an ECU which is already connected (with MC Database Open.vi, MC ECU Select.vi, MC ECU Open.vi, or MC ECU Connect.vi). The type of this reference depends on the property you want to get.
cluster Error in is a cluster which describes error conditions occurring before the VI executes. If an error has already occurred, the VI returns the value of the error in cluster to error out.
boolean status is TRUE if an error occurred. This VI is not executed when status is TRUE.
long unsigned integer code is the error code number identifying an error. A value of 0 means success. A negative value means error: VI did not execute the intended operation. A positive value means warning: VI executed intended operation, but an informational warning is returned. For a description of the code, wire the error cluster to a LabVIEW error-handling VI, such as the Simple Error Handler.
string source identifies the VI where the error occurred.

Output

long unsigned integer Reference out contains an ECU M&C task reference which can be wired through subsequent ECU M&C VIs.
polymorphic Value is a poly output value that returns the property value. You select the property returned in value by selecting the poly VI type. The data type of value is also determined by the poly VI selection. For information about the different properties provided by MC Get Property.vi, refer to the Poly VI Types table in the Description section. To select the property, right-click the VI, go to Select Type, and select the property by name.
cluster Error out describes error conditions. If the Error in cluster indicated an error, the Error out cluster contains the same information. Otherwise, Error out describes the error status of this VI.
boolean status is TRUE if an error occurred.
long signed integer code is the error code number identifying an error. A value of 0 means success. A negative value means error: VI did not execute the intended operation. A positive value means warning: VI executed intended operation, but an informational warning is returned. For a description of the code, wire the error cluster to a LabVIEW error-handling VI, such as the Simple Error Handler.
string source identifies the VI where the error occurred.

long signed integerECUCCPInterfaceReturns the interface initialized for the task, such as with MC DAQ Initialize.vi.
long unsigned integerECUCCPBaud RateReturns the Baud Rate used by the CAN interface with CCP protocol. Basic baud rates such as 125000 and 500000 are specified as the numeric value. Advanced (custom) baud rates are specific to the CAN interface type and can be found within NI-XNET or NI-CAN documentation. The default value of the property is the baud rate value defined by the A2L database file. You can change that value using MC Set Property.vi.
booleanECUCCPTerminationFor all XNET devices, the termination is software selectable. XNET provides the option of 120 Ω between Bus Plus and Bus Minus or no termination. The Termination property configures the onboard termination of the NI-XNET interface CAN connector (port). The Boolean property supports two values: TRUE = Termination ON and FALSE = Termination Off. However, different CAN or LIN hardware has different termination requirements, and the termination values have different meanings. Refer to the Termination attribute in the XNET API for more details. (This property is supported for NI-XNET devices only.)
long unsigned integerECUCCPStation AddressReturns the Station Address of the slave device. CCP is based on the idea, that several ECUs can share the same CAN Arbitration IDs for CCP communication. To avoid communication conflicts CCP defines a Station Address that has to be unique for all ECUs sharing the same CAN Arbitration IDs. Unless an ECU has been addressed by its Station Address, the ECU must not react to CCP commands sent by the CCP master.
stringECUCCPSeedKey Cal NameReturns the file name of the SeedKey DLL used for Calibration purposes. If SeedKey is configured for remote access, the output is RSK:<server ip address>,<port>.
stringECUCCPSeedKey DAQ NameReturns the file name of the SeedKey DLL used for DAQ purposes. If SeedKey is configured for remote access, the output is RSK:<server ip address>,<port>.
stringECUCCPSeedKey Prog NameReturns the file name of the SeedKey DLL used for programming purposes. If SeedKey is configured for remote access, the output is RSK:<server ip address>,<port>.
1D array (integer)ECUCCPMaster IdReturns CCP Master ID information. This ID information is optional and specific to the ECU implementation. For more information about the CCP master ID, refer to the documentation for the ECU.
1D array (integer)ECUCCPIdReturns the slave device identifier. This ID information is optional and specific to the ECU implementation. For more information about the CCP slave ID, refer to the documentation for the ECU.

booleanECUCCPSingle Byte DAQ List?Determines if an ECU supports single-byte or multi-byte DAQ list entries.
long unsigned integerECUCCPDTO TaskReturns the NI-CAN task reference for the DTO (Data Transmission Object, the CAN task reading frames from the slave device). For example, you might use this to set CAN properties for this task. Handle with extreme care, as those properties are usually set correctly by the ECU M&C Toolkit itself.
long unsigned integerECUCCPCRO TaskReturns the NI-CAN task reference for the CRO (Command Receive Object, the CAN task writing frames to the slave device). For example, you might use this to set CAN properties for this task. Handle with extreme care, as those properties are usually set correctly by the ECU M&C Toolkit itself.

long unsigned integerECUXCPCANDTO IdReturns the DTO ID (Data Transmission Object) which is used by the ECU to respond to XCP commands and send data and status information to the XCP master.
long unsigned integerECUXCPCANCRO IdReturns the CRO ID (Command Receive Object) which is used to send commands and data from the host to the slave device.
long unsigned integerECUXCPCANBaud RateThis is a legacy property and should no longer be used. Use the ECU:XCP:CAN:Baud Rate 64 instead.
quad unsigned integerECUXCPCANBaud Rate 64Indicates the Baud Rate in use by the CAN Interface with XCP protocol. Basic baud rates such as 125000 and 500000 are specified as numeric values. Advanced (or custom) baud rates are specific to the CAN interface in use and the description can be found in the NI-XNET or NI-CAN documentation. The default value for the property is the baud rate set in the A2L database used for the application.

If NI-XNET is used and the A2L file specifies a sampling point for the baud rate which differs from the sampling point used internally in NI-XNET, ECUMC replaces the standard baud rate value by a custom 64-bit baud rate which uses the sampling point as close as possible to the sampling point in A2L database. You can find the documentation for the NI-XNET custom baud rate in NI-XNET Hardware and Software Help under Interface:64bit Baud Rate.

You can change that value using MC Set Property.vi.

quad unsigned integerECUXCPCANFD Baud Rate 64Reads the CAN FD baud rate value (used for the data part of the transmission).

If CAN FD is used, Baud Rate 64 specifies the baud rate for the arbitration part of the CAN message, while FD Baud Rate 64 specifies the baud rate for the data part of the CAN message. CAN FD is only supported by NI-XNET interfaces for XCP protocol.

Basic baud rates such as 500000 and 2000000 are specified as numeric values. Information about the advanced (or custom) baud rates can be found in the NI-XNET Hardware and Software Help under Interface:CAN:64bit FD Baud Rate. The default value for the property is the baud rate set in the CAN_FD section of the A2L database used for the application. You can set the property to use any other baud rate or custom baud rate according to NI-XNET specification.

If the A2L file specifies a sampling point for the CAN FD baud rate which differs from the sampling point used internally in NI-XNET, ECUMC replaces the standard baud rate value by a custom 64-bit baud rate which uses the sampling point as close as possible to the sampling point in A2L database. Refer to the information about the custom baud rates in the NI-XNET Hardware and Software Help under Interface:64bit FD Baud Rate.

Transceiver Delay Compensation defined by the A2L database is not used while calculating the custom baud rate value, as the value is hardware implementation specific and the value found in the database may not match the NI-XNET specification. If you need very specific values for the CAN FD baud rate, you need to follow the NI-XNET documentation and set a custom baud rate using MC Set Property.vi.

long unsigned integerECUXCPCANCAN I/O ModeDetermines whether an XNET interface is running in CAN 2.0 mode (supports frames with payload up to 8 bytes), CAN FD mode (supports frames up to 64 bytes), or CAN FD+BRS mode (CAN FD with baud rate switching). CAN I/O Mode is only supported with XNET interfaces.

The default value is determined by the A2L database used by the application. The user can change the mode using this property to overwrite the mode set in the A2L database.

Valid values are CAN, CAN_FD, CAN_FD+BRS, and ECU Determined. The A2L database supports only CAN and CAN FD+BRS modes. The user can also set the mode to CAN_FD (without baud rate switching) using MC Set Property.vi.

In ECU Determined mode, the master can communicate with ECUs using either traditional CAN or CAN FD frames. The master starts the communication with a traditional CAN 2.0 frame; if the ECU responds in any mode, this mode is selected for further communication. If the ECU does not respond to the CAN 2.0 frame, the master repeats (after timeout) the first command using a CAN FD frame. In ECU Determined mode, the NI-XNET interface runs in CAN FD BRS mode, so the CAN FD baud rate must be set before using this mode. In CAN FD+BRS mode, the NI-XNET interface can receive and transmit CAN 2.0, CAN FD, and CAN FD+BRS frames.

0CAN 2.0
1CAN FD
2CAN FD+BRS
3ECU Determined
Note Note  CAN FD is only supported with NI-XNET version 17.0.1 or later.
32-bit integerECUXCPCANAct CAN I/O ModeThis read-only property allows querying the CAN I/O mode that is actually used when the CAN I/O mode is set to ECU Determined. As long as the mode has not been determined, the value is ECU Determined (refer to the CAN I/O Mode description for possible values). When the communication with the ECU has been established, the value changes to CAN 2.0, CAN FD, or CAN FD+BRS mode.
booleanECUXCPCANUse CAN Max DLCDetermines if the master in CAN 2.0 mode transmits frames with the actual used payload length or always transmits the maximum number of bytes (8 bytes).

The default value of this property is retrieved from the A2L database based on the MAX_DLC_REQUIRED keyword within the XCP_ON_CAN section.

word unsigned integerECUXCPCANCAN FD Max DLCDetermines the number of bytes transmitted by the master when the property ECU:XCP:CAN:Use CAN FD Max DLC is set to TRUE.

The default value of this property is retrieved from the A2L database based on the MAX_DLC keyword within the CAN_FD section.

booleanECUXCPCANUse CAN FD Max DLCDetermines if the master in CAN FD mode transmits frames with the actual used payload length or if it always transmits the maximum number of bytes, defined by the ECU:XCP:CAN FD Max DLC setting (8…64 bytes).

The default value of this property is retrieved from the A2L database based on the MAX_DLC_REQUIRED keyword within the CAN_FD section.

booleanECUXCPCANTerminationFor all XNET devices, the termination is software selectable. XNET provides the option of 120 Ω between Bus Plus and Bus Minus or no termination. The Termination property configures the onboard termination of the NI-XNET interface CAN or LIN connector (port). The Boolean property supports two values: TRUE = Termination ON and FALSE = Termination Off. However, different CAN or LIN hardware has different termination requirements, and the termination values have different meanings. Refer to the Termination attribute in the XNET API for more details. (This property is supported for NI-XNET devices only.)
stringECUXCPEthernetIP AddressReturns the IP address of the slave device. A slave device connected by Ethernet and TCP/IP or UDP/IP protocol is addressed by its IP Address and Port number.
word unsigned integerECUXCPEthernetIP PortReturns the IP Port number of the slave device. A slave device connected by Ethernet and TCP/IP or UDP/IP protocol is addressed by its IP Address and Port number.
word unsigned integerECUXCPEthernetIP Source PortReturns the source port (XCP master port) used for Ethernet communication. The default value is -1, which indicates that the source port will be chosen by the operating system. Valid port values are 0 to 65535. Note that port 0 is reserved and typically should not be used.
byte unsigned integerECUXCPSeedKey DllReturns the file name of the SeedKey DLL. If SeedKey is configured for remote access, the output is RSK:<server ip address>,<port>.

0x80...0xFF—User defined. It is possible to use different access modes for clearing and programming.

booleanECUXCPMeas Split AllowedReads the Meas Split Allowed property value.

For measurements in DAQ List mode, the master creates DAQ lists which determines frames with data transmitted by the ECU. The first byte in this frame (ODT) is a PID identifier, the remaining bytes in the frames are used for measurement data (e.g., with CAN 2.0, seven bytes can be used for data).

Depending on the type of measurement data, not all bytes of frames can be used. For example, measuring seven 32-bit values in the ECU requires transmitting seven frames per sampling point as only one 4-byte value can be placed in one frame. The remaining three bytes are unused.

The Meas Split Allowed property allows splitting the measurements across CAN frames, so the seven values can be packed into only four frames (4 frames * 7 bytes = 28 data bytes for DAQ data).

The default value for the property is read from the A2L database (keyword MEASUREMENT_SPLIT_ALLOWED within the XCP_ON_CAN block).

Note Caution  You can only use this feature when the ECU guarantees the value consistency across ODTs (frames), otherwise you might receive unexpected values.

file pathECULogFile PathReturns the filename (full path) where the XCP or CCP protocol traffic is logged in ASCII format for debugging purposes. An empty path indicates no logging (default). Note that on RT and cRIO systems, the logfile is created on the target system and must be transferred to the host after logging has been completed.

Note that no additional CAN port is used for the logging, which makes this method superior to any other method such as running a bus monitor parallel.

5: Table (Using Interpolation)

The related scaling is based on the TAB_INTP keyword within the A2L file, using interpolation between x-y pairs.

6: Table (Without Interpolation)

The related scaling is based on the TAB_NOINTP keyword within the A2L file, using x-y pairs without interpolation.

1D array (string)CharacteristicScalingText ValuesIf the scaling type is 2 = Enumeration Text or 3 = Range Text, you can use this property to request the list of text values that can be converted into raw values.
long unsigned integerCharacteristicSizesReturns the array Sizes for X and Y direction of the Characteristic.
double-precision, floating-pointCharacteristicX AxisReturns X-Axis values on which the Characteristic is defined. It is valid if the dimension of the selected Characteristic is 1 or 2.
double-precision, floating-pointCharacteristicY AxisReturns Y-Axis values on which the Characteristic is defined. It is valid if the dimension of the selected Characteristic is 2.
double-precision, floating-pointCharacteristicMaximumReturns the maximum value of the Characteristic.
double-precision, floating-pointCharacteristicMinimumReturns the minimum value of the Characteristic.
booleanCharacteristicRead Only?Returns if a Characteristic is set to Read Only. In this case it is not allowed to call MC Characteristic Write.vi for this Characteristic.
stringCharacteristicUnitReturns the unit string defined for this Characteristic in the A2L database.
stringCharacteristicCommentReturns the Comment string of the selected Characteristic.
stringFunctionCommentReturns the Comment string of the selected Function.
booleanGroupIsRootReturns whether the selected Group is a root-level Group entity.
stringGroupCommentReturns the Comment string of the selected Group.
long unsigned integerDAQModeReturns the selected I/O mode for the M&C Measurement task.

0—DAQ List

The data is transmitted by the ECU based on an event channel, which can be equidistant in time or sporadic. The data can be read back with the MC DAQ Read.vi as Single point data using sample rate = 0, or as a waveform using a sample rate > 0. Input channel data is received from the DAQ messages. Use MC DAQ Read.vi to obtain input samples as single-point, array, or waveform.

1—Polling

In this mode the data from the Measurement task is uploaded from the ECU whenever MC DAQ Read.vi is called.

double-precision, floating-pointDAQSample RateReturns the selected Sample Rate in Hz for the M&C Measurement task, which may be obtained with MC DAQ Initialize.vi.
long unsigned integerDAQ# ChannelsReturns the number of (scaled) channels initialized in a DAQ channel list of a M&C Measurement task. # Channels and # Raw Channels provide the number of array entries required when using MC DAQ Read.vi.
long unsigned integerDAQ# Raw ChannelsReturns the number of raw channels initialized in a DAQ channel list of a M&C Measurement task. # Channels and # Raw Channels provide the number of array entries required when using MC DAQ Read.vi.
stringDAQEvent Channel NameReturns the selected event channel name to which the Measurement task is assigned.
word unsigned integerDAQPrescalerReturns the prescaling factor which is used to reduce the desired transmission frequency of the associated DAQ list.
long unsigned integerDAQSamples PendingReturns the number of samples available to be read using MC DAQ Read.vi. If you set the number of samples to read input of MC DAQ Read.vi to this value, DAQ Read returns immediately without waiting. This property applies only to tasks initialized with mode of Input and sample rate greater than zero. For all other configurations, it returns an error. If this property is queried before the DAQ list is started, it always returns zero. Start the DAQ list first with MC DAQ Start Stop.vi before you query this property.
double-precision, floating-pointDAQTime Since Last FrameIndicates how much time has passed (in seconds) since the measurement session received the last DAQ frame. You can use this property to restart the measurement when the value increases a threshold (for example, 0.5 seconds), assuming the ECU stopped sending DAQ messages and must be restarted.

This property is read only.

double-precision, floating-pointDAQNum PIDsIndicates the number of PIDs (frames) used in the DAQ session. If the session does not use DAQ, the value is 0.

The number of PIDs is only valid after the DAQ list has been transmitted to the ECU, otherwise the returned value is 0. For example, you can call MC DAQ Start Stop.vi with the mode Transmit DAQ List to ECU after MC DAQ Initialize.vi, before reading this property.

This property is read only.

long unsigned integerDAQCCPDTO IdReturns the DTO ID (Data Transmission Object) which is used by the ECU to send DAQ list data to the CCP master.
long unsigned integerDAQCCPDTO TaskReturns the NI-CAN task reference for the DTO ID (Data Transmission Object, the CAN task reading frames from the slave device). For example, you might use this to set CAN properties for this task. Handle with extreme care, as those properties are usually set correctly by the ECU M&C Toolkit itself.
long unsigned integerDAQXCPTiming SourceReads the DAQ Timing Source property value. The default is Automatic. Values are:
0Automatic

The default method (1, 2, or 3, below) is selected.

1Host Timing

Timestamps are generated from the host system time whenever a frame arrives.

This mode is always available.

This is the default for XCP on TCP/UDP if the ECU does not support timestamps.

2CAN Timing

Timestamps are generated from the network interface hardware (e.g., NI-XNET hardware).

This mode is available only if the network hardware generates timestamps.

This is the default for XCP on CAN if the ECU does not support timestamps.

3ECU Timing

Timestamps are taken from the ECU data. The Start Time is taken from the host, and increments are taken from the ECU.

This mode is only available if the ECU generates timestamps; in this case, it is default.

stringDAQ ListNameName of the DAQ list (measurement source). Pass the DAQ list number converted to a string in the Name parameter of Get Property. The available DAQ list number can be obtained by the ECU DAQ List Numbers property.
stringDAQ ListDisplay IdentifierOptional property you can use as a display name as an alternative to the DAQ List Name property.
long unsigned integerDAQ ListCAN IDReturns the CAN ID for the specified DAQ list if mcPropDAQList_CANIdSelectMode == CAN_ID_FIXED.
long unsigned integerDAQ ListCAN ID Select Mode Returns the condition for selecting the CAN ID for the specified DAQ list.

0—CAN_ID_FIXED

The CAN Identifier is a predefined fixed number.

1—CAN_ID_VARIABLE

The CAN Identifier is a variable number.

2—CAN_ID_DTO_ID

The CAN Identifier is the same as the DTO identifier.

long unsigned integerDAQ ListEvent ChannelsReturns a list of event channel numbers that can be used with the given DAQ list. The DAQ list is determined by the name input containing a string representation of the decimal DAQ list number, e.g., '2.'
1D arrayDAQ ListExcluded DAQ ListsReturns an array containing the numbers of DAQ lists not working together with the current DAQ list.
byte unsigned integerDAQ ListFirst PIDReturns the first Packet ID for the specified DAQ list.
word unsigned integerDAQ ListMax LengthReturns the maximal length of the DAQ list.
long unsigned integerDAQ ListReduction AllowedReturns whether or not the specified DAQ list allows reduction.
long unsigned integerVersionMajorReturns the major version of the ECU M&C software, such as the 1 in version 1.2.5.
long unsigned integerVersionMinorReturns the minor version of the ECU M&C software, such as the 2 in version 1.2.5.
long unsigned integerVersionUpdateReturns the update version of the ECU M&C software, such as the 5 in version 1.1.5.
long unsigned integerVersionBuildReturns the build number of the ECU M&C software. This number applies to the Development, Alpha, and Beta phases only, and should be ignored for the Release phase.
stringVersionCommentReturns a comment string for the ECU M&C software. If you received a custom release of ECU M&C from National Instruments, this comment often describes special features of the release.
