    The user should check whether the application firmware installed in the converter is covered ® by this user manual. It can be done through CAN bus using Axiomatic Electronic Assistant (EA) software. The user manual is valid for application firmware with the same major version number as the user manual.

  • Page 6: Converter Description

    2.2 Software Organization The LIN – J1939 CAN Protocol Converter with PWM Output belongs to a family of Axiomatic smart controllers with configurable internal architecture. This architecture allows building a converting algorithm based on a set of predefined internal configurable function blocks without the need of custom software.

  • Page 9: Network Bus Terminating Resistors

    The converter takes its network ECU Address from a pool of addresses assigned to self- configurable ECUs. The default address can be changed during an arbitration process or upon receiving a commanded address message. The new address value will be stored in a non- volatile memory and used next time for claiming the network address.

  • Page 10: Converter Logical Structure

    CONVERTER LOGICAL STRUCTURE The converter is internally organized as a set of function blocks, which can be individually configured and arbitrarily connected together to achieve the required system functionality, see Figure 2.

  • Page 11: Function Block Signals

    Each function block is absolutely independent and has its own set of configuration parameters, aka setpoints. The configuration parameters can be viewed and changed through CAN bus ® using Axiomatic Electronic Assistant (EA) software. LIN interface is presented by the LIN Signal function blocks and function blocks controlling sending and receiving of the LIN signals.

    3.2.1 Digital PWM/Digital Frequency Simply setting the “Output at Minimum Command” and “Output at Maximum Command” to corresponding value in each range will drive the output to different range options. The unit of measurement for PWM output variables is percentage [%] and Hertz [Hz] for the frequency output.

  • Page 16: Common Parameters

    When the output is being driven by the Control Input, the state is logically set to OFF when the Control Input is zero and is set to ON whenever a non-zero value is written. By default, ‘Normal Logic’ is used. The resulting Drive State will depend on the “Digital Control Response” as the table below.
  • Page 17 By default, the “Control Source” is setup to be ‘CAN Receive Message’. In other words, the output will response in a linear fashion to the corresponding CAN received command data. The “Control Source” together with “Control Number” parameter determine which signal is used to drive the output.
  • Page 18 When an Enable input is used, the output will be shutoff as per the “Enable Response” in the table below. If the response is selected as a disable signal (3 or 4), when the enable input is ON, the output will be shut off. Table 10.

    The output is inherently protected against a short/open circuit. In the case of a dead short, or an open circuit, the hardware will automatically disable the output drive, regardless of what the processor is commanding for the output. The processor will be flagged by the hardware that the output circuitry has been shutoff due to a short or an open at the output, but it will not know which type it is.

These 2 setpoints will change the resolution of the X Values or Y Values, respectively, with the decimal digits value user chooses. Keep in mind that any change on the decimal digits will make effect to the current X values or Y values.

    (i.e. transmitted over CAN), then Xmin would be -20 and Xmax would be 125 when used the linear formula. In all cases, the controller looks at the entire range of the data in the Y-Axis setpoints and selects the lowest value as the MinOutRange and the highest value as the MaxOutRange. They are passed directly to other function blocks as the limits on the Lookup Table output.

  • Page 31: Point To Point Response

    For example, with a 0.5 to 4.5V input (X-Axis) driving a 0 to 1500mA output (Y-Axis), the default points would be setup as per figure (a) below. However, a 100Ω to 54kΩ input (X-Axis) representing 120ºC to -30ºC (Y-Axis) would be setup as per figure (b) below. In each case, the user would have to adjust the table for the desired response.

  • Page 33: X-Axis, Time Response

    3.4.5 X-Axis, Time Response As mentioned in Section 3.4, a Lookup Table can also be used to get a custom output response where the “X-Axis Type” is a ‘Time Response.’ When this is selected, the X-Axis now represents time, in units of milliseconds, while the Y-Axis still represents the output of the function block.
  • Page 34 An application where this feature would be useful is filling a clutch when a transmission is engaged. An example of some fill profiles is shown in the figure below. Figure 18. Lookup Table Time Response Clutch Fill Profiles In a time response, the interval time between each point on the X-axis can be set anywhere from 1ms to 24 hours.

    3.5 Programmable Logic Function Block Figure 20. Programmable Logic Function Block This function block is obviously the most complicated of them all, but very powerful. The Programmable Logic can be linked to up to three tables, any one of which would be selected only under given conditions.
  • Page 37 Should the conditions be such that a particular table (1, 2 or 3) has been selected as described in Section 3.5.2, then the output from the selected table, at any given time, will be passed directly to the Logic Output. Therefore, up to three different responses to the same input, or three different responses to different inputs, can become the input to another function block, such as PWM Output.

  • Page 39: Conditions Evaluation

    3.5.1 Conditions Evaluation The first step in determining which table will be selected as the active table is to first evaluate the conditions associated with a given table. Each table has associated with it up to three conditions that can be evaluated. Argument Z is always a logical output from another function block.
  • Page 40 3.5.2 Table Selection In order to determine if a particular table will be selected, logical operations are performed on the results of the conditions as determined by the logic in Section 3.5. There are several logical combinations that can be selected, as listed in the table below. Table 23.

  • Page 42: Logic Block Output

    3.5.3 Logic Block Output Recall that Table X, where X = 1 to 3 in the Programmable Logic function block does NOT mean Lookup Table 1 to 3. Each table has a setpoint “Table X – Lookup Table Block Number” which allows the user to select which Lookup Tables they want associated with a particular Programmable Logic Block.

    3.6 Math Function Block Figure 22. Programmable Logic Flowchart There are four mathematic function blocks that allow the user to define basic algorithms. A math function block can take up to four input signals, as listed in Table 8 in Section 3.2.4. Each input is then scaled according the associated limit and scaling setpoints.

  • Page 45: Constant Data

    For the arithmetic functions (9 to 14), it is recommended to scale the data such that the resulting operation will not exceed full scale (0 to 100%) and saturate the output result. When dividing, a zero InB value will always result is a zero output value for the associated function.

    3.9 Diagnostic Function Block There are several types of diagnostics supported by the converter. As described in Section 3.2.4, fault detection and reaction are associated with the output drive. In addition, it can also detect/react to power supply over/under voltage measurements, a processor over-temperature, or lost communication events.
  • Page 54 Over Temperature Over Temperature Shutdown Lost Communication Received Message Timeout (any) When applicable, a hysteresis setpoint is provided to prevent the rapid setting and clearing of the error flag when the measured value is right near the fault detection threshold.
