Hello Elliott,what exactly do you mean by "30 CAN controllers"? For controlling 3000 devices this seems much rather the number of CAN bus segments than CAN controllers. Hmmm .... 100 would still sound like quite a large number of devices per segment. Not all CAN chips can drive a load of 100 nodes on TP media - will you be using CAN on optical links?
What form factor/OS to you want to use for the IOCs? What CAN application level protocol do your ~3000 devices speak? Regards, Ralph On 16.06.2009 18:03 Elliott Wolin wrote:
Hi,For the Hall D detector at Jefferson Lab we have to control about 3000 CAN devices distributed among 30 or more CAN controllers. Any suggestions on how to do this (hardware and software)?Thanks,
