Page 5: Overview Of Controller
The various function blocks supported by the 1IN-1OUT-LED are outlined in the following sections. All setpoints are configurable using Axiomatic service tool, the Axiomatic Electronic Assistant (EA). The universal input can be configured to read analog signals: Voltage, Current, and Resistance as well as digital signals: Frequency/RPM, PWM, Digital, and Counter types. -
Page 6: Dual Led Output Function Block
Additionally, the 1IN-1OUT-LED includes a dual LED which is visible from outside the housing. The LED can be configured in various ways to visually inform the user of the controller’s operations. The LED configuration is described in more detail in section 1.2. 1.2. -
Page 7: Universal Input Function Block
In ‘Normal On/Off’ response type, the output command state will follow the control input command: when the control input command is ON, the output will be turned ON and vice-versa. In ‘Blinking Logic’ response type, the output will toggle at a period of ‘Digital Blink Rate’ for as long as the input command is ON. -

Active High / Active Low Options In the case of Digital Inputs, the options Active High/Active Low are used to configure how a signal high or signal low is interpreted. -
Page 9: Counter Type
1.3.4. Counter Type The 1IN-1OUT-LED controller supports three different variations of the Counter input type. These variations are listed in Table 7 below: Pulses Within Measuring Window Time Measurement of Pulse Count Trigger on Pulse Count Completion Table 7 – Counter Input Types The first option Pulses Within Measuring Window is used to count the number of pulses that occur within a configurable time frame (Measuring Window) in terms of milliseconds. -

Thus, the output signal is not an analog one. In order to create an analog signal, a simple low pass filter can be connected externally to the controller.

The measured current through the load is available to be broadcasted on a CAN message if desired. It is also used as the input to the diagnostic function block for each output, and an open or shorted output can be broadcasted in a DM1 message on the CAN network 1.7. - Page 19 Each system will have to be turned for the optimum output response.

Page 20: Diagnostic Function Blocks
1.8. Diagnostic Function Blocks The 1IN-1OUT-LED supports diagnostic messaging. DM1 message is a message, containing Active Diagnostic Trouble Codes (DTC) that is sent to the J1939 network in case a fault has been detected. A Diagnostic Trouble Code is defined by the J1939 standard as a four byte value. In addition to supporting the DM1 message, the following are supported: Previously Active Diagnostic Trouble Codes Sent only on request... - Page 21 Figure 4 – Double Minimum and Maximum Error Thresholds In case any of the Diagnostics blocks is configured to monitor Output Current Feedback, there is an internal error status flag maintained automatically for that particular output. This internal flag can be used for driving the particular output to a specified state in case of diagnostic event using Proportional Current Output setpoints “Control Fault Response”, “Output in Fault Mode”...

Page 24: Simple Conditional Logic Function Blocks
1.9. Simple Conditional Logic Function Blocks The Simple Conditional Logic Blocks provide a way of connecting different blocks and comparing them to one another. The output of the Conditional Logic Blocks is either 0 (FALSE) or 1 (TRUE). There are three operations that take place in the Conditional Logic Blocks which allows the user to make more elaborate comparisons. -

Xmax) will be set to 5.5V so editing the maximum X Value to something higher than 5.5V the Axiomatic Electronic Assistant will display a warning. It is up to the user’s discretion to appropriately select the values in the Lookup Tables when Auto Update on Setpoint Changes is set to FALSE. -
Page 27: Default Configuration, Data Response
However, if some of the data points are ‘Ignored’ as described in Section 1.11.4, they will not be used in the Y-Axis range determination. Only the Y-Axis values shown on the Axiomatic EA will be considered when establishing the limits of the table when it is used to drive another function block, such as a Math Function Block. - Page 28 Figure 5 – Lookup Table with “Ramp To” Data Response Alternatively, the user could select a ‘Jump To’ response for “Point N – Response”, where N = 1 to 10. In this case, any input value between X to X will result in an output from the Lookup Table function block of Y An example of a Math function block (0 to 100) used to control a default table (0 to 100) but with a...

Page 29: X-Axis, Time Response
1.11.6. X-Axis, Time Response As mentioned in Section 1.11, 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. There is also another setpoint associated to the Lookup Table when configured to Time Response which is the Table Auto-Cycle setpoint. -

The Programmable Logic can be linked to up to three tables, any one of which would be selected only under given conditions. Any three tables (of the available 8) can be associated with the logic, and which ones are used is fully configurable.

To use a constant as the second argument in the operation, set “Table X, Condition Y, Argument 2 Source” to ‘Control Constant Data.’ Note that the constant value has no unit associated with it in the Axiomatic EA, so the user must set it as needed for the application. - Page 34 1.12.2. 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 1.12.1. There are several logical combinations that can be selected, as listed in Table 27. Default Table Cnd1 And Cnd2 And Cnd3 Cnd1 Or Cnd2 Or Cnd3...

Page 35: Logic Block Output
1.12.3. 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. -
Page 36: Math Function Block
1.13. Math Function Block There are four mathematical function blocks that allow the user to define basic algorithms. A math function block can take up to four input signals. Each input is then scaled according to the associated limit and scaling setpoints. Inputs are converted into percentage value based on the “Function X Input Y Minimum”... -

When dividing, a zero InB value will always result is a zero output value for the associated function. When subtracting, a negative result will always be treated as a zero, unless the function is multiplied by a negative one, or the inputs are scaled with a negative coefficient first. 1.14. -

Page 59: Reflashing Over Can With The Axiomatic Ea Bootloader
This section details the simple step-by-step instructions to upload new firmware provided by Axiomatic onto the unit via CAN, without requiring it to be disconnected from the J1939 network. 1. When the Axiomatic EA first connects to the ECU, the Bootloader Information section will display the following information. - Page 60 3. When the prompt box asks if you want to reset the ECU, select Yes. 4. Upon reset, the ECU will no longer show up on the J1939 network as an AX021610 but rather as J1939 Bootloader #1. Note that the bootloader is NOT Arbitrary Address Capable. This means that if you want to have multiple bootloaders running simultaneously (not recommended) you would have to manually change the address for each one before activating the next, or there will be address conflicts, and only one ECU would show up as the bootloader.

- Page 62 If you select to reset the ECU, the new version of the AX021610 application will start running, and the ECU will be identified as such by the Axiomatic EA. Otherwise, the next time the ECU is power-cycled, the AX021610 application will run rather than the bootloader function.
