CANoe 7.x in Virtual Machine

[Bertil Bäck-2]

Hi,
just got a new computer on my work and is going to be stuck with this
one a while now. So I went with 6gig ram and win7 x64. As for now Vector
does not have any drivers for x64 windows. I have installed CANoe in a
Windows Virtual Machine (XP mode). The program installs without
problems. When I connect my CANcaseXL and forward it to the virtual
machine I am asked to intall the drivers, but the driver fails to
install with error "Code 10".

My question is, have anybody else have tried to run CANoe in a Virtual
Machine and got it working. Virtualbox? VMware?

Hello Bertil,

I cannot say much about virtual machine usage itself.

CANoe itself is running on w7 x32 in the moment. The official support including all components and add-ons for w7 x32 is planned for end of the year/beginning of the next year. With this also w7 x64 in the 32 bit compatibility mode is planned. For running this, the x64 CANcaseXL drivers will be required. They will be available end of February.

Best regards
Juergen

Hi Juergen,
thanks for the time schedule information. Checked this with vector-scandinavia before I tried to go virtual :)

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.

Applause!  Awesome!

All done on little old CANbus!

I bet your bus schematic is almost as impressive as those big rings.

Not nearly as much as you might think.

PC to USB to 9S12 Controller.  9S12 Controller to 6 Bridges where two of
the bridges are run from one channel of the 9S12.  After that, a Thick
DeviceNet cable from the each of the bridge channels to a set of 50
connectors that go to the lamps. The cable is terminated at the end with a
120 Ohm resistor.

Essentially 40 metres of cable where the last 10m has the 50 nodes.  Power
is 48VDC this time, to reduce the voltage drop and common mode shift since
the CAN signal ground isn't isolated.

Really the most difficult part is dealing with 150 nodes on a bus that is
30m off the ground.  Every node has to have a unique ID #.  During
installation, each position was supposed to be filled with the correct
node ID#.  Unfortunately this didn't always happen. With almost 1600
lights where the Node ID# went from 2 to 151 and then repeated again ended
up with duplications and mistakes in labelling.

Each lamp CPU board has a unique 4 digit serial number programmed into
EEROM.  Additionally the LED board has a one wire Dallas Serial # and
temperature sensor.  That's been helpful where a programming mistake put a
duplicate serial # into the CPU EEROM.

A node on the network that has the same value as another (it's happened)
can be targetted and reprogrammed with a new node ID without sending
someone up to pull it down.  A node in the wrong position can also be
given the correct # so light patterns happen in sequence.

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.

Thanks,

Guillermo

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.

John

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,

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.

It's been an exhausting 2.5 months.
