In this article, we take a look at the Kvaser DIN Rail and how to control this device using CANlib.
The Kvaser DIN Rail family is a collection of Ethernet to CAN/CAN FD interfaces with support for I/O ports via add-on modules. The housing has a mounting clip that attaches to a 35 mm Top Hat DIN rail for easy installation. The I/O pins can be controlled either from Kvaser’s CANlib SDK (over Ethernet) or directly on the unit using Kvaser t programs. The I/O modules currently available are:
• Digital add-on module with 16 inputs and 16 outputs, Kvaser DIN Rail S010-X10 (01065-9)
• Analog add-on module with 4 inputs and 4 outputs, Kvaser DIN Rail S020-X10 (01066-6)
• Relay add-on module with 8 relay outputs and 8 digital inputs, Kvaser DIN Rail S030-X11 (01067-3)
Up to four, optional, add-on modules (in any combination) may be attached to the side of the base module.
In order to use the Kvaser DIN Rail, a compatible version of the Kvaser driver and firmware must be installed. The latest version of the driver and firmware can be downloaded from https://www.kvaser.com/download. The next step is to find and connect the Kvaser DIN Rail using the Kvaser Network Device Selector found in Kvaser Device Guide. Please refer to the Kvaser DIN Rail User’s Guide, which can also be downloaded from https://www.kvaser.com/download for more details of the initial setup.
The Digital In will be read relative to GND DI and the Digital Out will be set relative to GND DO, so we need to connect GND DI to GND DO in order to read the output value correctly.
DO9, DI9 and so on is the marking on the add-on module, when enumerated, these will be given pin number 8 and pin number 24 respectively, given that we have only connected a Digital add-on module.
The base module supports up to four add-on modules in any configuration. The base module enumerates the I/O pins on the add-on modules with consecutive integer pin numbers starting with 0 for the first pin on the first module, 1 for the second pin on the first module, and so on until the last pin on the last module. Removing, adding or changing the order of the add-on modules will cause the base module to re-enumerate all I/O pins to match the new configuration and set all output I/O pins to zero.
As a cautionary measure, before confirming a new configuration (i.e. a new enumeration of the I/O pins), we can only retrieve information about the pins. After we have confirmed the configuration, we may set and read values on the pins.
Before continuing, let’s take a look at a small examples which does the basic setup and then sets and reads some Digital pins.
Running the above code results in the following on the screen:
As previously stated, a configuration needs to be confirmed before any values on pins may be read or set. The reason being that if you set the wrong output in a live installation, bad things may happen. So let us take a look at how to verify a configuration using the Python wrapper.
In the Python canlib package, we can define our own module specification which can be compared to the actual configuration before confirmation. Any attributes in the module specification set to ‘None‘ is automatically considered fulfilled. The actual comparision is done using ‘Configuration.issubset(module_spec)‘. This means that it is possible, but not needed, to set constraints on the firmware version or serial number of the add-on modules.
The entire process is superbly inefficient. Rich from New Eagle got frustrated and said to himself, “Instead of downloading it to an embedded PC …wouldn’t it be great if we can download it to use in the production ECU and skip all the steps in between?”[/vc_column_text][vc_row_inner][vc_column_inner width="2/3"][vc_column_text]And then, with his teams at New Eagle, Rich went on to help create just that. New Eagle tools allows someone to compile directly from MATLAB / Simulink into Raptor, which auto-generates the C-code to be downloaded to the production ECU, via a Kvaser Leaf Light. In this way, Kvaser’s CAN tools help New Eagle simplify and shorten the customer’s design cycle.[/vc_column_text][/vc_column_inner][vc_column_inner width="1/3"][vc_raket_product list_style="list" post_id="12027"][/vc_column_inner][/vc_row_inner][vc_header_raket header_type="h3" header="Solution: Move to scalable volume production, quickly."][vc_column_text]For New Eagle, the whole goal is to move a customer into a scalable volume production, quickly. It does so, in part, by leveraging Kvaser’s products. New Eagle has three internal business units: Creator – Integrator – Supplier. First, Product Engineering (Creator) builds the Raptor tools, Raptor-enabled ECUs and displays. Second, Application Engineering (Integrator) is available to assist customers with development if they don’t have the capacity, or build a turn-key solution for customers who want that, or simply provide training on the tools to those customers who want to build it themselves. Lastly, New Eagle’s distribution arm (Supplier) is a reseller for a variety of products, including Kvaser’s products, as well as many ECUs, motors, and inverters. New Eagle’s relationships with major volume producers can help to unlock many products related to vehicle development. Kvaser fits carefully into all of New Eagle’s business units, making Kvaser invaluable to the company’s ongoing business operations.[/vc_column_text][vc_column_text]

“Calibration is a very powerful way to help debug what’s going on in real time, and, also to help tune the system in real time. We found that Kvaser CAN interface hardware increased our value to Pi Innovo customers by reducing time and therefore cost to develop their embedded system.”[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][vc_header_raket header_type="h3" header="What’s Next on the Horizon for Pi Innovo?"][vc_column_text]Pi Innovo is currently looking at the Electric Vertical Take-off and Landing market (eVTOL) … in other words, flying cars! Flying taxis in Dubai could conceivably happen by 2022. eVTOL is an answer to ever-increasing congestion. Carnie suggests:
“A lot of the same principles apply to eVTOL as do to Electric Vehicles, and this is where Pi Innovo is looking to make traction. There are over 140 different companies working on these types of systems, world-wide. While it is still an emerging market and technology, there is a lot of activity around it. We have products that can and are being used today, and Kvaser will definitely add value to those eVTOL projects.”Pi Innovo is particularly interested in further developing the Electric Vehicle supervisory control. Their controller would become the “coordinating brain” of the vehicle, which requires a great deal of data from the outside world. The issue is how to process that data at adequate speeds. Ethernet provides the necessary bandwidth and Pi Innovo is therefore researching the need for Automotive Ethernet and determining which tools will be needed. However, Carnie concludes:
“CAN bus will always have a role to play.”[/vc_column_text][vc_separator_raket][/vc_column][/vc_row][vc_row][vc_column][vc_header_raket header_type="h3" header="Get In Touch:"][vc_raket_qsr post_id="9633"][/vc_column][/vc_row] [post_title] => Reducing Costs and Improving Efficiency for Pi Innovo with Kvaser’s Real-Time Interfaces [post_excerpt] => [post_status] => publish [comment_status] => open [ping_status] => open [post_password] => [post_name] => reducing-costs-and-improving-efficiency-for-pi-innovo-with-kvasers-real-time-interfaces [to_ping] => [pinged] => [post_modified] => 2022-04-04 10:19:10 [post_modified_gmt] => 2022-04-04 10:19:10 [post_content_filtered] => [post_parent] => 0 [guid] => https://www.kvaser.com/?p=26698 [menu_order] => 0 [post_type] => post [post_mime_type] => [comment_count] => 0 [filter] => raw ) [9] => WP_Post Object ( [ID] => 26800 [post_author] => 1121 [post_date] => 2019-12-02 14:17:44 [post_date_gmt] => 2019-12-02 14:17:44 [post_content] => [vc_row][vc_column][vc_single_image image="26761"][vc_column_text] [/vc_column_text][vc_column_text]It is well known, in the CAN community at least, that every CAN and CAN FD network should be terminated with a 120 Ohm resistor at each end of the bus. More information can be found on ‘Why use a resistor?’ and how to maximise signal quality in the whitepaper ‘Using termination to ensure recessive bit transmission’, but what is rarely discussed is how to test if it works correctly. The good news is that, with the right equipment, this is relatively simple! To check your network’s termination, disconnect the CAN interface’s D-sub 9 pin from the network and measure resistance through the cable by placing a digital multimeter / ohmmeter between pin 2 and 7. Make sure any CAN nodes e.g. a motor controller, are still attached but powered down. If your termination is correct, you should read approximately 60 Ohms (two 120 Ohm resistors in parallel produce a resistance of 60 Ohms). If you read a different value, continue testing as follows:[/vc_column_text][vc_column_text]1. Check that there is 10 kOhm between CANH and the ground, including the power supply. This test is best done without any CAN-communication on the CAN-bus, and will highlight any short cuts between CANH and the surrounding area.[/vc_column_text][vc_column_text]2. Check that there is 10 kOhm between CANL and the ground, including the power supply. Again, do this without communication on the CAN bus. [/vc_column_text][vc_column_text]3. If there’s still a problem, connect an oscilloscope to the CANH signal, which should show a signal level at 2.5 Volt during the idle phase, with the voltage increasing to 4 Volt for the dominant bits and dropping back to 2.5 Volt for the recessive bits. The shape of the bits should be nice and square, without any ringing on the rising and falling edges. [/vc_column_text][vc_column_text]
a. If the idle level differs from 2.5 Volt, it could result from bad common ground.
b. If CANH is fixed at a certain level, it may be due to a shortcut to other electrical circuits.
c. If the units do not have a common ground, a voltage offset will result that is proportional to the ground offset.
d. If there is ground noise, it could be impossible to do this measurement. A differential probe is necessary to obtain the voltage on CANH relative to CANL. Please note, CAN could work fine even if the ground noise is more than 40 Volt peak to peak with a frequency from 0 to 500 MHz.
e. All ringing is caused by impedance mismatch, of which the major cause is a drop-line from the main CAN bus to the CAN units. Generally, the unit impedance is 100 kOhm, resulting in a 100% reflection of the energy back to the main CAN bus, delayed by the propagation delay in the drop-line. This energy will return back to the main CAN bus with 0 phase shift. Alternatively, the EMC filter could cause a phase-shift in the reflected energy.
[/vc_column_text][vc_column_text]4. The next step is to connect an oscilloscope to the CANL signal, which should also show a signal level of 2.5 Volt during the idle phase, with the voltage decreasing to 1 Volt for the dominant bits and rising back to 2.5 Volt for the recessive bits. The shape of the bits should be nice and square without any ringing on the rising and falling edges. All other results are similar in cause to CANH, as listed above.[/vc_column_text][vc_column_text]5. If there is a lot of ground noise, it will be necessary to use a differential probe to display the signal difference between CANH and CANL. The oscilloscope should show 0 Volt during the idle phase, with a voltage increase to 1 Volt for the dominant bits, falling back to 0 Volt for the recessive bits. The shape of the bits should be nice and square without any ringing on the rising and falling edges. Note that if either CANL or CANH is shorted, it will result in a lower signal level on the dominant amplitude.
