It's a good question.

I was asked a similar one about a week ago.  Why didn't I use RS485 and
DMX512 which is the defacto standard for light shows and theatre lighting
systems.

DMX-512 uses 250kbps, RS485 and a burst of bytes where each byte
represents an intensity.  Where the byte is in the block of bytes is
picked up by the light.  If a light is RGB, then there are 3 bytes in a
row for each lamp.  If you want a group intensity so that the colour shade
stays the same with the same RGB values but it just gets dimmer then you
need 4 bytes per lamp.  That's now 64 lamps per universe I think it's
called.

Anyway,  DMX512 requires a large number of masters that need to be linked
to the central controller.  Say I used one universe per USB,  I'd need 30
USB ports.  That's not going to work.  The alternative is Ethernet which
is commonly used with DMX512.   That would be handy.  PC to Ethernet.
Ethernet to RS485.  RS485 to 50 lamps.

But wait, DMX512 is uni-directional.  Did the lamp get the message?  Is
the lamp even working?  From a fuzzy security camera 200m away it's hard
to tell which lamps are on and off.  Much nicer to ask the lamp if it's
still awake and talking.

I could design an offshoot of DMX512 which then polled each lamp after a
sequence of brightness messages.  Add CRC and other ACK/NAK messaging and
I'd have a working RS485 system but it wouldn't be DMX-512.

So there's lamp CPU module design,  Ethernet Controller module design,
RS485 protocol design, PC software.   All in just 2 months.  That's from
05DEC08 to 04FEB08 on the original project before mid January the scope
was changed from 100 lamps per set to 150. (Hence the CAN Bridges).

The next question which is always a design criteria is cost.  A CAN driver
is only slightly more expensive than an RS485 driver.  PIC processors have
serial ports but many have CAN at again a slightly higher price.  For the
original project of about 550 devices one dollar isn't that much money in
the total scheme of things so CAN or RS485 from a cost perspective, when
the communications protocol for CAN is already in place, is not that much
money for a one time project verses software costs.

One controller with 5 CAN ports on an evaluation board (SofTec 9S12) and
100 nodes per port was a simple decision given the time frame.  Then 2.5
weeks before the deadline, (mid January) the criteria was changed to 150
lamps per CAN port. Oops.  Over the 120 node limit.  TKE to the rescue
with their bridge.  Back down to 50 nodes per port.  Cost was now higher.


But overall, a few dollars per node for CAN verses $35 or so per RF link
means RF never entered the equation since power had to be run to the lamps
anyway.  An Ethernet to RS485 wasn't bi-directional and Ethernet to CAN
would have been more expensive once the quantity was factored in.

Fast forward to the end of August and the request for a two sided set.  In
two months we had to manufacture double the number of nodes and also a
dedicated 9S12 board since the original eval board was no longer made.
Technological Arts in Toronto did have a 9S12 board but I'd have to still
lay out a driver board and modify the software to use it.  It became
easier to create a custom five CAN 9S12 module with the relay drivers and
USB interface.

It's all about costs and delivery dates.  RF just wasn't an option.

Hello,

You can't imagine how fantastic this is - so many people have
undervalued the power of switch in CAN-networks since I presented the
concept first time in 2003. So, many thanks to John and his team and
gratulations for the new world record! Should be good feeling to get
the 2:nd world record and before the games have started ;-)

Best regards,

Congratulations. It should be very satisfying to see your invention used in such a beautiful way. Pretty amazing. My question is: in networks of such an enormous size and with difficult access to the nodes, why didn't you go wireless? Why is it better to keep using the "old" CAN bus? I think that currently this question will have to be answered for many developments and I would like to know your opinion, if you don't mind to share it.

Subject: [CANLIST] CANCardXL buffer management marco.melani01@...

Hi all,
I need a little help for the following issues using CANCardXL:
- I want to transmit a periodic messages (period=10ms) on the CAN bus using CAPL
to simulate a new ECU. The rest bus is a real bus and may happen that latency
for bus access is greater than the period.
Do you know if the old data are overwritten?
It seems that period transmission request is delayed until the previous message
transmission is finished.

Thanks for your help.

Marco.

Subject: [CANLIST] Large CAN System

Hello everyone,

I'm afraid my record for the largest CAN system has been broken.  Up till
now the largest was 742 nodes configured into 5 groups of 3x50 node
networks driven from the TKE WCS-10s.  It was a mixed network where due to
cable length and too many errors, I had to back down some segments from
1Mbps to 500kbps.  The WCS-10 bridges were reconfigured to take 500kbps in
and send out the other 3 CAN ports either 500kbps or 1Mbps.

Well, we've gone and doubled it.  Twice as nodes and twice as many bridges
plus an extra 70 specialty nodes. Two brand new from scratch Freescale
based 9S12 USB to 5 CAN port System Controller with high side relay
drivers for relay power activation and dry contact inputs for feedback
that the relays are active.

Here's a video of the system in action.

http://www.youtube.com/watch?v=zQkfbiju8CY

It's been an exhausting 2.5 months.

Hi Steve – I’m looking for a PCI-104 device (see here: http://en.wikipedia.org/wiki/PCI-104). It looks to me like the PCIcan and PCIcanx products are half length PCI cards. Right bus, but wrong form factor! Unless it’s still too early in the morning and I’m missing something obvious.

Michael,

we offer boards with 4 CAN channels for QNX 6.x :
for both, Basic CAN (SJA1000) and Full CAN (Bosch CC770)

Our offered CAN boards with 4 CAN channels are OEM versions of boards from EMS Wuensche. I saw that their PCI-104 boards with 4 channels are not online, yet, but they are available! You can check their PCI board online with the same design:

Hi,

Correct me if I am not misstaken - but I would be suprised if the Kvaser
PC104+ (or other vendors) are not stackable, so you can put two on top of
eachother? (But maybe you knew that and this was answer to your question
(maybe you don't have room for that for example)).

Hi Ulrik - I suspect that you are correct in thinking that they can be
stacked - but as you guessed we have space restrictions that will make it
difficult to use more than one PCI-104 card.

Hello,

yes, you can put PC104+ and PC104 boards on top of each others ... but the number of boards per a stack is limited to 4 , IMHO.

PC104 boards need PC resources like free device memory, free I/O ports and interrupts (not shareable) ... I have seen PC104 boards which are using 1 hardware
interrupt per controller ! However ... a 4 channel board seems to be the best solution.

Best Regards

can4linux is available too for the PC104m at least,
the one equipped with up to four sja1000.
If the electric design is the same as for the PCI boards,
the driver can be used for the PCI-104 as well.

Hello again,

we have asked EMS-Wuensche to put online their data sheet for the PCI-104 board with 4 CAN channels.
Here it is, it should be exactly what you are looking for:

Hi � does anybody know of a PCI-104 or PC-104+ card that had 4 CAN controllers built in? The best I�ve been able to find is a dual CAN controller card.

Thanks!

Yes it is.

The boards (PCI, PCI-104 and PC-104) are supported by Socket CAN too.

can4linux is available too for the PC104m at least,
the one equipped with up to four sja1000.
If the electric design is the same as for the PCI boards,
the driver can be used for the PCI-104 as well.

Yes it is.
The boards (PCI, PCI-104 and PC-104) are supported by Socket CAN too.

The design of the electronic of a PC/104 (ISA) and a PC/104plus (PCI) board is completely different.
An individual driver has to care about these different designs.

The driver provided by can4linux is a multi board driver which supports ISA and PCI devices ... but there is necessary an individual configuration of the driver .
But that driver offers the same API for the development of CAN based applications, what seems also the case with the Socket CAN interface.

Hi,

I just need to verify CAN peripheral on an ARM11 processor is functional or not.

What is the best and easy way to do that?

My processor just has a CAN controller, it doesn't have a transceiver.

Is it possible at all to verify CAN without having transceiver?

Also what do the waveforms of CAN TxD and CAN RxD look like?

Can I verify the peripheral probing these waveforms?

Any ideas?

Thanks,

Girish

We have currently some prototype COTS HW with socket and we are not happy with it.
With ARM9-architecture running Linux there seems to be a some problems in task switching and thus heavy CPU-load.
What kind of CPU-loads or response times whould one expect from this implementation?

Subject: [CANLIST] Re: Socket CAN (Re: Re: Fwd: Quad PCI-104/PC-104+ CAN card?) canlist@...

Hi,

well, one problem of Socket CAN is the poor usage/utilization of socket
buffers within the Linux kernel. I mean the socket interface of the
kernel is intentionally be used for greater transfer than just a single
CAN message (8bytes and DLC and ID). This results in many context
switches and a lot of overhead within the kernel. But that is not only a
problem of Socket CAN, can4linux and many other CAN APIs are making a
context switch per message for sending/receiving too (I know there a
some APIs with a kind of bulk transfer).

I did some performance tests here with an Atmel AT91SAM9262... The test
application used 3 threads (sending - slept to most time, receiving,
processing) and I came to 1500 message per seconds in receiving
direction. This isn't by far a good result, but I think it can be improved.

Improvment depends on your application. If you need low latency and a
maximum of throughput with low CPU load, why not implement your protocol
in kernel space like BCM and ISOTP (already available for Socket CAN). I
can think about a J1939 implementation especially for large transfers
using the transport protocol or a ISO11783 with ETP. Move this stuff to
kernel space may also be an option for more or less time critical tasks
like periodic sending of many messages.

PS: There is also a realtime version of Socket CAN for Xenomai available.

Hello,

I have 24V Devices which are now controlled over CAN and  mostly  it  is
working already.

Now I like to know, which connectors are recommended for the CAN-Bus.

I need mostly automotive versions, some of the  devices  need  at  least
IP67 and I was already on the website of "Tyco Electronics" looking  for
connectors but I gaved up after 6 hours of search.

Any suggestions?

CiA 303-1 DR V1.6: CANopen additional specification Part 1: Cabling and
connector pin assignment IGCO_303_1v01060001.pdf

CiA 418 DS V1.0.1: CANopen device profile for battery modules
IGCO_418v01000102.pdf

CiA 419 DS V1.0.1: CANopen device profile for battery charger
IGCO_419v01000102.pdf

and yes, I am already on the bottom of the page.  Is there a problem?

I have found the button by examing the Souce Code of the Webpage.  Maybe
it should be redesigned... The button is hidden in the front of

     CiA� and CANopen� are registered Community Trademarks of...

at the end of the Page and I can reach the button, if I disable the  CSS
Stylesheet.

Hello Michelle,

In case Your environment is not extremely bad, I'd go for M12.
It is widely used e.g. in construction machinery.
Connector is fairly good, although it is meant only for assembly purposes, not to get opened and closed dozens of times.
Batch cables are available from many suppliers and thus pricing is also pretty good.

You can also power small current units through the connector.
However, You must pay attention on the short circuit protection since wire sizes are usually 0,34/0,5mm2 and with longer cables (above 10m) standard slow circuit breakers possibly dont operate at all.
We have made some tests with 0.5mm2 cable with length of 25m having complete short circuit at the other end. After half an hour circuit was still closed<g>
Based on these experiences we have selected a special 2A breaker for this use.

In case You need more power, You could go to thick devicenet cabling with7/8” connector.

You could try

	Subject:	[CANLIST] Which connectors are recommended?

Hello, I have 24V Devices which are now controlled over CAN and mostly it is working already. Now I like to know, which connectors are recommended for the CAN-Bus. I need mostly automotive versions, some of the devices need at least IP67 and I was already on the website of "Tyco Electronics" looking for connectors but I gaved up after 6 hours of search. Any suggestions?

This is perfect.

Then I have to find a supplier/manufactuer/distributor in France/Germany
since I do not know the connectors.

Interesting information.

Most stuff has under 0.5A.

This does not work (MS IIS Error; forbidden directory access) and  if  I
choose only the domain I am redirected  to  a  badly  translated  german
website http://venlo.netzgiganten.de/ (the website is a mixup of  german
and english)  :-/

I think, I wil bother/blame the webmaster a little bit... :-D

However, I have  checked  Belden/Lumberg  and  contacted  them  with  an
inquiry for suitable CANopen/M1 products.

Hello Michelle,

Molex (Brad Harrison) has some manufacturing and development in Germany (Bretten) and manufacturing in Poland.
To be honest, I havent got a faintest idea on their network in Germany.
In case You need a connection to Molex/distributor, I think I can arrange one.
Send me a direct email.
