Hi Roland, I do not want to make big advertisment here in this forum, but have a look at our webpage, we have a lot of buscouplers for external io. (CAN, Ethernet Powerlink, ...) Also maybe interesting for you is, that we are working on a xenomai driver for ethernet powerlink (http://www.ethernet-powerlink.org/) which will be finished in a few days...

Hi, Sorry about the subject but I badly need some advice. I have tried 2 different makes of remote IO over CAN to achieve my 1ms control loop. The makes are WAGO and Schleicher. These are industrial modules that link to buscouplers (in my case CAN) and make the IO available to andy device that can talk CAN. In this case my xenomai'd PC platform. However both makes (and all others I have contacted) have bus couplers which are too slow to achieve this. 5ms is about the best they can do. The engineering departments (who were not aware of this restriction) agree that it is not a fundamental CAN problem but a matter of their hardware not being able to respond fast enough. I have given up hope of finding suppliers who can supply industrial (the latter is important) equipment that will give me what I am looking for based on CAN. So I am willing to settle on another bus protocol (I will still be using CAN for other sensors which are responding fast enough on CAN) for the remote IO. Can anyone tell me what companies can supply remote IO that is fast enough. Can anyone comment on the use of RTNET (real time ethernet I believe) with xenomai. I ahve not seen any evidence of it being alove on this mailing list.
