  • Byte Order
    Byte order in the frame payload. This property is a ring (enumerated list) and is required.
  • Comment
    Comment describing the signal (string).
  • Configuration Status
    Configuration status of the signal. This property is used only if you change the Database property Show Invalid From Open? from false (default) to true.
  • Data Type
    Data type in the frame payload. This property is a ring (enumerated list). This property is required.
  • Default Value
    Default value of the signal, specified as scaled floating point units (DBL).
  • Frame
    Frame that contains the signal (XNET Frame I/O Name).
  • Maximum Value
    Maximum value of the signal, specified as scaled floating point units (DBL).
  • Minimum Value
    Minimum value of the signal, specified as scaled floating point units (DBL).
  • Mux:Data Multiplexer?
    Configures whether this signal is a data multiplexer (boolean)? When the parent frame is data multiplexed (also known as mode dependent), it contains a special signal called the multiplexer. The value of the multiplexer signal determines which subframe is used.
  • Mux:Dynamic?
    Specifies whether this signal is data multiplexed, also known as dynamic (boolean). Signals that depend on the multiplexer are considered dynamic (this property true), and are contained in a subframe. Signals that are common to all frame values are considered static (this property false).
  • Mux:Multiplexer Value
    When Mux:Dynamic? is true, this specifies the dynamic subframe in which the signal is contained. When the value of the data multiplexer signal matches this value, the dynamic signal exists in the frame.
  • Mux:Subframe
    Subframe that contains the signal (XNET Subframe I/O Name). This property is valid only when the Mux:Dynamic? property is true.
  • Name (Short)
    Short name of the signal (string). The I/O name (long name) contains qualifiers to ensure that it is unique, such as the database, cluster, and frame name. If you write this property, it changes both short and long name (see Detailed help).
  • Number of Bits
    Number of bits in the frame payload (1-64). This property is required.
  • PDU
    PDU that contains the signal (XNET PDU I/O Name).
  • Scaling Factor
    Scaling factor used to convert bits in frame payload to/from scaled floating point units. The scaling factor is the A in the linear scaling formula AX+B, where X is the raw data, and B is the scaling offset.
  • Scaling Offset
    Scaling offset used to convert bits in frame payload to/from scaled floating point units. The scaling offset is the B in the linear scaling formula AX+B, where X is the raw data, and A is the scaling factor.
  • Start Bit
    Starting position in the frame payload. The range is 0 (lowest bit in the first byte) to 63 (highest bit in the last byte) for CAN. The range is 0 to 2031 for FlexRay. This property is required.
  • Unit
    Describes the units for the scaled floating point value (string). The string is no more than 80 characters in length. You can use this string to display units (i.e. rpm) along with the signal's data.
