6076	I'm new to CAN and this is my first mail to this group I have a basic question on identifier. 1. Is identifier the destination address? If not, what should be...	김재용 Jae-Y... jykim@...	May 25, 2007 5:09 am
6077	Hello, ... In CAN, the message identifier identifies the contents encapsulated into message, neither source nor destination in CAN-level. Some application...	heikki.saha@...	May 25, 2007 6:16 am
6078	Hello, I have a funny question regarding to DS-301: which are the valid Transmission Types for RXPDOs? Is it possible that the types 1-253 are not in use at...	Bende Georg georg.bende@...	May 25, 2007 9:19 am
6079	Hello, ... Yes, they are. Use of synchronized PDO reception is defined in page 34 of CiA-301 v. 4.115. It is another issue, wheather it is useful to use...	heikki.saha@...	May 25, 2007 10:54 am
6080	Hello, Syncronized PDO reception is very much needed - just imagine more axles that have to start the same time. But for me it reads under p. 9.2.1.1: "The...	Bende Georg georg.bende@...	May 25, 2007 2:29 pm
6081	Hello It is true that CAN specifically itself does not specify what you put in either the ID or data fields. You can put any number in there and CAN does not...	Robert Boys RBoys@...	May 31, 2007 11:38 am
6082	If you are new to CAN, I am sure you might find this link useful. www.kvaser.com/can/protocol/main.htm ... -- Archives and useful links:...	Vikram Rajput vsrajput@...	May 31, 2007 3:57 pm
6083	Hi all, For a project I'm looking for a cheap controller board supporting WinCE, CAN 2.0A, and Ethernet 100 Mbit/s. Preferably also sw support for the ...	Rob Hulsebos rob.hulsebos@...	Jun 7, 2007 10:24 am
6084	Hi, I am new to the CAN bus systems and seeking to improve my knowledge on this. My question is "How many nodes a CAN bus system has?" I heard that LIN has...	vamsi ak avamsik.aftek@...	Jun 8, 2007 2:37 pm
6085	Hi Vamsi, It depends on the standand you are using, for instance : - ISO 11898-2 (CAN High Speed) and ISO 11898-3 (CAN Fault Tolerant) says that there is no...	Marcelo Rodrigues msrmailxxx@...	Jun 8, 2007 3:48 pm
6086	Hello. I am studying ways to implement physical redundance on CAN networks, and a particular question is disturbing me. If I have two different pair cables...	Gilvan Tessari gt@...	Jun 8, 2007 4:03 pm
6087	Hi, CAN could have as many nodes as there are ID values but the real limitation is the drivers. The bus as two termination resistors that in parallel result...	John Dammeyer johnd@...	Jun 8, 2007 5:15 pm
6088	Hello Vamsi, The ISO-11898-2 standard recommends 30 nodes with a signaling rate of 1 Mbps and a bus length of 40 m with 120ohm characteristic impedance UTP ...	Corrigan, Steve s-corrigan1@...	Jun 8, 2007 5:47 pm
6089	Hello Gilvan, Sounds kind of tricky to me. What you're building is something like a star topology, and termination becomes a concern. A CAN driver is...	Corrigan, Steve s-corrigan1@...	Jun 8, 2007 6:00 pm
6090	... John is correct the number of nodes is restricted by the number of ID. Which is 2 power 29 with extended IDs. The physical limitation, caused by available...	Heinz-Jürgen Oertel oe@...	Jun 8, 2007 6:58 pm
6091	Hello, Steve. Maybe my description wasn't accurate. The topology is daisy chain, but I use two physical paths between two network nodes, and I have just one ...	Gilvan Tessari gt@...	Jun 8, 2007 7:39 pm
6092	Hello Gilvan, Using two transceivers makes sense. If you just AND the two RX lines and one bus fails, there is a chance that one RX line is stuck at low. This...	Daniel Leu daniel.leu@...	Jun 8, 2007 8:53 pm
6093	Gilvan, The two distant node are not meant to communicate with each other? Rgds, Steve ... From: canlist-owner@......	Corrigan, Steve s-corrigan1@...	Jun 8, 2007 10:00 pm
6094	Hello Gilvan I think I understand what you are trying to do. As an example, I can think of a fault tolerant shipboard system. Two nodes at either end of the...	John Dammeyer johnd@...	Jun 8, 2007 10:33 pm
6095	Hi, Thanks steav, rodrigues, John and Heinz-J�rgen for your replies which are very usefull. And I have one more question, May I know how many nodes would be...	vamsi ak avamsik.aftek@...	Jun 9, 2007 1:07 pm
6096	Hi, ��When you use HIGH SPEED CAN, the max number of CAN nodes is determined by Bus Baudrate. When Bus Baudrate is 1M, the max number of CAN nodes is 32....	lgao@...	Jun 9, 2007 1:33 pm
6097	... I don't know the typical number of CAN nodes in cars. I'm more familiar with CAN application in automation. But I think you can expect up to 70-80 nodes,...	Heinz-J�rgen Oertel oe@...	Jun 9, 2007 3:28 pm
6098	Sorry. That's just plain wrong! The bit rate does not restrict the number of nodes. A couple of things here: It's not baud rate it's bit rate. The Baud rate...	John Dammeyer johnd@...	Jun 9, 2007 6:54 pm
6099	The cars made by the companies for which my employer works typically have a minimum of 2 busses. For automotive, "high speed" CAN is in the order of 500kbps,...	Geoff Field geoff_field2003@...	Jun 10, 2007 11:46 am
6100	Hello Gilvan, As long as you are using two separate physical networks, your concept shall work. By using cables with almost equal lenghts, propagation delay...	heikki.saha@...	Jun 11, 2007 5:48 am
6101	Practically, I think the number of nodes does limit the bit rate. If we're going to be pedantic, then we should acknowledge that the so-called terminating...	Charles Manning Charles.Manning@...	Jun 11, 2007 5:49 am
6102	Hello, John is right. The "fan-out" has been separately defined for most CAN transceiver chips and it varies from 30 to 127. There is also other important...	heikki.saha@...	Jun 11, 2007 5:57 am
6103	Hi john, Thank you very much for your infomation as for the before answer i was confused but now its clear. I think "More nodes, worse Bus electrical ...	vamsi ak avamsik.aftek@...	Jun 11, 2007 8:04 am
6104	Hi, Steven. The nodes will communicate with each other. The point is that the electric signal must go through two different physical paths. At this time, I...	Gilvan Tessari gt@...	Jun 11, 2007 3:36 pm
6105	OK. You've made a rather sweeping statement that could potentially become one of these urban legends that don't appear to have any direct evidence but are...	John Dammeyer johnd@...	Jun 11, 2007 6:38 pm
