manual assumes that you are familiar with the Sigma Elite system and Pi Workshop software. Manuals for these are available from Cosworth upon request. This manual covers the Lightweight Logger Box (LLB) the Lightweight Junction Box (LJB), and aspects of Pi Workshop which are needed to set up the LLB and the LJB. The Lightweight Logger Box (LLB) The Lightweight Logger Box (LLB) is a compact Logger/Control Unit for use in motor sport applications. The LLB combines most of the functionality of the existing Pi Sigma Logger Card and Application Card, with additional CAN ports. However, the LLB does not have any I/O capability, as this is provided by Lightweight Junction Box (LJB). The LLB provides these main features: nn nn nn nn nn 100BaseT Ethernet port for connection to a PC running Pi Server Pi Tebnet network for connecting to other Pi Sigma systems RS232 Debug communications port Five CAN ports (2 on the Logger node and 3 on the Application node) Seven user serial ports (6 on the Logger node and 1 on the Application node) 7 The Lightweight Junction Box (LJB) The Lightweight Junction Box (LJB) is much smaller and lighter, and will operate in hotter and harsher environments than Pi Sigma 5–card and 3–card MCUs. Unlike other Pi Sigma units, the LJB does not have a group structure or IO cards. Instead the LJB comprises a number of Super blocks. Each Super block uses either a single pin, or a pair of pins as inputs or outputs. Some Super blocks can be divided into blocks at build time and cannot be changed by the user. For example Analog input 1 (AI1) can be configured to be either two single ended inputs, or as one double ended input. The LJB digital inputs have a quicker response than embedded I/O inputs and the analog inputs have a similar accuracy to Selectronic cards. The LJB allows the user to write their own local control loops and user algorithms for extended functions (e.g. PID loops). In addition it also allows the user the ability to create bespoke low level algorithms. A range of algorithms for standard functions (i.e. beacon processing) are included in the LJB. These algorithms are similar in principal to Pi Sigma applications, supporting faster rate tasks (up to 4KHz). Access to private Input/Output (I/O) nn Excitations are not tied to specific inputs or outputs nn No coupling between blocks nn Regulated excitations are sufficiently accurate so that ‘ratiometric’ inputs are not required nn Separate tool to configure block structure nn Import output file into Pi Workshop Set-up. 8 LLB and LJB User Guide Typical System Wheelspeed 31 analog inputs (front) Wheelspeed Download Debug Tire Performance System (cost option) Front LJB to ECU Pi TEBNET Pi telemetry (cost option) Steering wheel dash LLB OR Omega Shift/Alarm LED module Omega dash ALARM OIL Remote driver switch PS FUEL BAR LAP Research KPH MPH V LAP OIL WAT o F oC Pi TEBNET OR Gear/shift and Alarm modules Compact dash Switches to CAN box Beacon transmitter (no cost option) Sigma Beacon Rear LJB Wheelspeed Wheelspeed display lap code select split 31 analog inputs (rear) Typical system showing some cost options 9 Specifications LLB Functional Specifications The LLB has the following specification: nn nn nn nn nn nn nn nn nn 128MB of logging memory Dual redundant Pi Tebnet network ports to connect to other Pi Sigma units 100BaseT connection to Pi Server for downloads Six serial ports on the Logger Card Two CAN ports dedicated for switches and FIA Protocol on the Logger Card One serial port in the Application Module Three CAN ports in the Application Module Three integral ± 10G accelerometers (longitudinal, vertical and lateral) Debug channels for battery voltage, current and box temperature LLB electrical specifications nn Unit will turn on when input voltage increases above 10.5V nn Will operate with continuous voltage down to 8.5V nn Will operate with continuous voltage up to 20.0V, and with transients not exceeding 10ms up to 35V nn Will survive, but not operate, with continuous voltage up to 35V nn Power consumption approximately 8 Watts. 10 LLB and LJB User Guide LLB Technical Specifications The LLB technical specifications are listed below.

LLB Power Requirements The LLB needs a supply voltage greater than 10.5 volts to start-up and between 8.5 volts and 20.0 volts to operate correctly. If the supply voltage is outside the 8.5 volts and 20.0 volts limits, the LLB will switch off. Connecting the LLB LLB connector pin 1 (VBATT+) and pin 3 (VBATT–) are used to supply power to the LLB.   Installation 17 LLB Dimensions Use the following information when fitting an LLB. The LLB should be fitted using the antivibration mounts supplied. 26.00 (1.02”) 88.00 (3.46”) 16.40 (0.64”) 76.00 (3.00”) 35.00 (1.37”) 68.20 (2.68”) LLB dimensions in millimetres and (inches) 18 LLB and LJB User Guide 12.65 (0.49”) 100.00 (3.93”) 101.60 (4.00”) 65.00 (2.55”) The LLB contains three identical accelerometers which are used to measure acceleration about three axes: longitudinal, vertical and lateral. The accelerometers have corresponding channels in the Pi Workshop software. The LLB standard orientation axes are shown in the following figure. Vertical acceleration +ve Longitudinal acceleration —ve Lateral acceleration —ve Front of car Lateral acceleration +ve Longitudinal acceleration +ve Vertical acceleration —ve LLB standard orientation axes   Installation 19 Installation LLB Orientation LLB Re-orientation You can mount the LLB in a different orientation to the standard. The three axes of acceleration (longitudinal, vertical and lateral) will still be measured, but by a different accelerometer to that used in the standard orientation. The channel names in Pi Workshop software remain the same, although they will be measuring acceleration along a different axis. You must set up a math channel in Pi Workshop software to make use of the information from each channel. Refer to the Pi Workshop User Guide for information on how to set up a math channel to make use of the acceleration information if you fit the LLB in a non standard orientation. LJB Power Requirements The LJB needs a supply voltage greater than 10.5 volts to start-up and between 8.5 volts and 20.0 volts to operate correctly. If the supply voltage is outside the 8.5 volts and 20.0 volts limits, the LJB will switch off. Connecting the LJB The power required by the LJB from the car battery means that both of the VBATT+ pins (connector pins 3 and 4) and both VBATT– pins (connector pins 1 and 2) must be used. Mounting the LJB The LJB should be fitted within the cradle provided. For mounting and fitting instructions refer to Pi Research document “29M-071642-1E LJB mounting instructions”. 20 LLB and LJB User Guide The LLB Lightweight Logger Box The Lightweight Logger Box (LLB) The LLB has been designed for fitting in the cockpit or sidepod areas of a racing car.

The LJB is provided with built-in mechanisms for carrying out certain functions – wheel speeds, beacon processing and so on – but such that extra algorithms can be written by a user in a way that is seamless to Pi Workshop. These algorithms behave much like Pi Sigma applications, running rate tasks and sourcing and sinking channels, but with a capability of faster rate tasks and also with access to private IO. The logical layout of the LJB is shown below. 46 LLB and LJB User Guide Pi Tebnet Channel Algorithm Block Port Channel Algorithm Port Port Block Block The LJB Channel Port Outside world IO interface Channel Port and setup interface Automatic transfer Channel table Port Channel Block Port (Note that Algorithms acessing ports actually do so via the channel table) Logical layout of the LJB On the righthand side is the interface to the IO hardware (the blocks) connecting to the outside world. On the lefthand side is the standard Pi Tebnet channel table connecting to the rest of the system. In the middle are algorithms which can use the hardware on the right (accessing the ports), and also sink and source channels to the channel table on the lefthand side, following normal Pi Sigma rules. Also, blocks can transfer their values directly to the channel table automatically.   The LJB 47 Super-blocks and Blocks The IO hardware is split into a number of super-blocks, each capable of being configured for defined functions. There are a defined set of super-block types, and for each type, one or more instances of them are available in the hardware. Some of those super-block types can be set to perform one of a number of functions. For instance, super-block type Analog input 1 (AI1) has a number of blocks. Each block can operate as either 2x single ended inputs or as 1x milli-volt differential input, but not both at once, because the pins and hardware are shared. The process for setting this is known as super-block configuration. Configuration of each super-block is carried out at manufacture or code load time; it cannot be changed by the user with Pi Workshop. For information on possible build time configurations see section Input/output (I/O). After configuration, each super-block therefore devolves into one or more blocks, which provide the actual hardware available to operate with. It may be more than one set of hardware as in case of Analog input 1 (AI1): one of the two configurations available is 2x single ended input, so when the configuration to this mode is made for a specific AI1 superblock, the module ends up with two blocks with 1x single ended input each. Whereas, if the differential option was selected, there would be only one resulting block. 48 LLB and LJB User Guide Configuration of Results in 1 double ended input Value to system Setup Analog input 1 type functional super-block OR 2 single ended inputs Value to system Setup Value to system The LJB Setup Example configuration of Analog input 1 (AI1) super-block Once configuration is complete, the result is therefore a set of blocks. Each of these blocks has a defined type, though there may be several instances of the same type. Each of these blocks is completely independent, and all setup parameters for it can be made without any coupling to any other block. Their runtime IO values are also uncoupled. The runtime values from a block are available via ports, and are mapped directly to the channel table and therefore will be available across Pi Tebnet at all rates in the usual way. Note that: nn For super-blocks of the same type, their capabilities (available blocks) and method of configuration will be identical. nn For blocks of the same type, their capabilities (available ports) and method of setup will be identical. Normalisation (or scaling) for ports will also be identical for all blocks of a given type – possibly affected by block setup, but not affected by the source of the block (its parent super-block). Therefore, the super-blocks are the source of all the blocks, but it is the blocks – not the super-blocks – that provide the actual IO.   The LJB 49 Use Of Blocks Blocks can be used one of in two ways: nn nn Either Pi Workshop can control the block and access its ports (allocating them to channels in the same way as for IO card ports) Or they can be accessed directly by algorithms (via the channel table). But, not both at once. Whoever is the owner of a block is responsible for setting it up, and only that owner may access its ports. Setup for each block is carried out by the owner. In brief, for Pi Workshop owned blocks, the OS will read a file from the Logger card at startup which will contain the setup. For algorithm owned blocks, the algorithm is responsible for carrying out setup, as and when it wishes. Specific setup depends on the block type, but will consist of usual parameters such as acquisition and output rates, and so on. 50 LLB and LJB User Guide Algorithms Algorithms are like mini Pi Sigma applications in that they can source and sink channels to and from other parts of the system via Pi Tebnet, but they also have access to ‘private’ hardware, via the blocks and their ports. Algorithms are written so that they directly manipulate the hardware (via device drivers or channel table entries) for the various blocks they own. Algorithms are able to run at all Pi Tebnet rates (and also at higher rates of 2 and 4KHz, bandwidth permitting), though it must be noted that channel transfer with the rest of the system can only happen at Pi Tebnet rates. Where algorithms are accessing block ports, they will be responsible for all normalisation and calibration that needs to occur between the port and algorithm. The comparison between applications and algorithms is as follows: Application Channels Source and sink are specified in FSR Maths channels Yes Access to hardware Usually not Rate tasks Yes, 1s to 1mS Background tasks Yes Messaging Yes Non-volatile items Yes Setup table Yes Event generation Yes   Algorithm Source and sink are specified in FSR Yes Yes Yes, 1s to 0.25mS (but can only transfer channels across Pi Tebnet at 1s to 1mS) Yes Yes No No Yes The LJB 51 The LJB Feature Examples Of Block Use Example 1: Example 1: The standard wheelspeed mechanism is implemented directly in a block. There is therefore no software algorithm involved. The setup for each wheelspeed (filter depth etc.) is generated by Pi Workshop, and the resulting values (level, filtered period, snapshot period, and count) made available across Pi Tebnet and assigned to channels. Example 2: It might be desired to implement a completely different wheelspeed algorithm (using the same hardware). In that case an algorithm could be written that utilised one or more of the shaft/wheel speed blocks, and then made available to other filtered wheel or shaft speed channel values from the algorithm. This, for instance, could dynamically vary the filter depth at will. In this case the blocks used for this would not be available to Pi Workshop, thus its ports could not be assigned directly to channels. Example 3: A simple PID algorithm might access two or three blocks, for instance a feedback analogue input (an LVDT), an LVDT excitation and a balanced analog moog current drive output. It would at the least require to sink one channel value to give a demand position (and probably there would be a lot more - both sink and source). Transfers managed directly to Pi Tebnet from ports transfer the raw values with normalisation and calibration carried out at destination for inputs and at source for outputs and will happen within the input/output phase of their rate cycle. However since algorithms are really just mini-applications running on a floating point enabled processor, channel value transfer between them and Pi Tebnet can be in engineering units if desired, but like any other application there will always be a one rate cycle delay. 52 LLB and LJB User Guide Who Owns A Block Algorithms get first call on a block. As part of the algorithm code writing process, it is necessary to decide which blocks are to be used. The availability information is then passed to Pi Workshop, which can use the remainder. Pi Workshop is hard-coded to understand the capabilities of the block types and instances available within the LJB (thus also their ports, channel table locations and setup), and Pi Workshop is also passed the configuration information contained within the FSR. Pi Workshop will therefore be aware of which ports are available for channel allocation, and what setup options there are. Blocks and ports available to Pi Workshop can only change on an LJB code change. Blocks, ports and setup The LJB Blocks have specific setup formats depending on their types. If a specific block is not setup, it will be passive, transferring no data in either direction. Block ports have the following attributes: nn nn nn nn nn nn nn Name Address (channel table location) Direction Data type Normalisation (depends on setup) Quantity / units Maximum and minimum rates Setup for Pi Workshop owned blocks For blocks that are not being used by algorithms, Pi Workshop can allocate channels to the ports of a block. Pi Workshop will therefore allow the user to assign channels to ports, will understand any coupling between ports on the same block, and will allow the user to make the necessary setup choices. Pi Workshop will create a setup file containing a list of block setups. This is loaded to the logger card as part of the standard Send Setup process. At start up of the LJB, following the configuration phase, the LJB Operating System   The LJB 53 requests the setup file from the Logger card using Pi Tebnet messaging. The LJB Operating System will then read the setup records in the file and apply them to the specified blocks. After that it need do nothing else as values are transferred automatically at the correct times between the ports and channel table. Setup for algorithm owned blocks This is completely at the discretion of the algorithm, and may be carried out (and changed) at any time without affecting any other block. Algorithms must therefore understand the setup format of any blocks they use. Setup for algorithms The LJB does not have a filestore and algorithms do not have any setup tables, so the possible means by which algorithms may set up their blocks are: nn nn nn nn 54 Hard-coded - the algorithm knows exactly how to setup a block By channels - channels from an application can contain setup, and the algorithm and application must agree on the meanings. By message - algorithms will be able to register MSIDs and therefore receive messages. An application can therefore send setup in a message. Any combination of the above. LLB and LJB User Guide Input/output (I/O) The LJB is organised so that individual pins, or pairs of pins (in one case four pins), are connected to internal units which are known as super-blocks. These super-blocks are given functions as described below. Note that: nn nn Excitations are not tied to specific inputs or outputs There is no concept of ratiometric analog inputs (excluding LVDTs) - regulated excitations are sufficiently accurate so as to make this unnecessary. In most cases a pin or set of pins may have more than one selectable function, settable by ‘mode’ - the ‘mode’ setting turns a super-block into one or more blocks which are the actual functioning blocks of I/O. There is no coupling between different blocks - setup for one cannot affect another, and run time channels are not coupled in any way. LJB Configuration The LJB has a number of analog and digital super-blocks and ports which can be configured in different combinations by Pi Research when the LJB is manufactured. There are three categories of variables which control this configuration of an LJB: nn nn nn Build configuration. This results in a Build Code. If the LJB configuration needs to be changed, the LJB must be returned to Pi Research. Runtime setup. Using Pi Workshop some channels can, for example, have the Excitation switched On or Off, or the Sample rate can be changed. Runtime variables. These are I/O values that are obtained mainly via Pi Tebnet ports from sensors. The following sections detail the types of channels which can be configured, the numbers of each type of channels and the type of Runtime variable that the channel will accept.   The LJB 55 The LJB nn nn Standard Build Configuration The LJB is supplied with a standard configuration which is listed below.

These are ports with a limited rate range (1Hz to 100Hz). Complex Internal Algorithms Most algorithms (e.g. ADC input) are self explanatory. The more complex one’s are described below. Phase Detection For Torque There is no hardware assistance or internal algorithm for torque measurement. However since all digital input pins are routed to the TPUs, it is intended that torque measurement will be possible by writing user algorithms that make use of TPU functionality. PID Closed Loop There is no hardware assistance or internal algorithm for PID closed loop control, though it is possible for local algorithms to be written to provide this, and sample code is available from Pi Research. 78 LLB and LJB User Guide Wheel And Shaft Speed This algorithm is actually provided directly by hardware. The algorithm provided is the current rolling average algorithm implemented in the embedded IO card, with the following differences: nn nn nn nn nn The capture clock frequency is fixed at 8MHz. The capture registers are 26 bit. The capture and subtraction is implemented directly in hardware, and therefore is able to run to a much higher input pulse rate. The maximum input pulse is limited by the capability of the input conditioning circuitry. The rolling average capture buffer is 128 registers deep. This, with the fact that there is no input divider, implies that the number of teeth in a wheel revolution (for wheelspeed) should be 128 or less. The rate of data transfer onto Pi Tebnet will cover the whole Pi Tebnet range. The rate value transferred to the consumer is the average time between the most recent capture and that ‘n’ captures ago (normalisation provides the divide by ‘n’), where ‘n’ may be between 1 and 128. The count is the total count of teeth seen, modulo 232. The wheel and shaft speed detection hardware take the following setup: nn nn nn nn nn 79 Setting the rolling average filter depth ‘n’ and provides as ports: the count of teeth seen the most recent tooth period the total period for the most recent ‘n’ teeth or stopped indication input level post input conditioning LLB and LJB User Guide Declaration of Conformity 80 LLB and LJB User Guide Conditions Of Use - LJB The Lightweight Junction Box (LJB) is intended for use in motorsport applications only, i.e. not on vehicles used on the public road network.

Stop Detection enabled When the shaft is stopped or moving very slowly the speed is set to zero. A guide to the minimum speed is shown. RPM requires that the pulses to average over is the same as the number of teeth on the sensor target over 1 revolution. KPH requires that the wheel diameter is 640mm (as an example tyre size - if its different then the minimum speed will change). The stop status will be cleared when two teeth have passed the sensor since the stop (at a speed greater than the minimum). Stop Detection disabled The result in this case will always be the shaft speed calculation without stop detection. If the shaft is running at a speed lower than the minimum then the timebase counter will overflow and results will be unpredictable. This might be useful for an advanced user who doesn’t want the slower results to be hidden by the stop detector. Pi Research recommend that Stop Detector is enabled for all standard users as it prevents erroneous results.
