Re: Allnet A20 CAN controller

Hello,

Isto got the point. The most exciting in CANopen is, that device profile number tells extremely
lot about the "marvellous product". If a product conforms an appropriate device profile, basics
may be assumed to be OK. But, if the device does not conform any profile, either vendor or device
or both are more or less out of sense.

Among too many people there is too weak understanding, how important is to support the standardized
system integration framework as well as possible. Almost each device can be integrated by using
"brute force"-method, which leads too expensive and error-prone production and service actions. Of
course the primary service of a device shall also meet the specs, but problems in that area has been
in far better shape than in the system integration side.

Best regards,

Hello, 

completely off the topic. 
This is one of those manuals which makes one say "pitäkää tunkkinne" (keep You f... trunk) 

To explain a bit: 
There was this one finnish humourish TV-serie, where in one sketch guys had problems with a tyre in their car. 
One of the guys started walking towards a house near by and while walking started thinking things like: What if there is no one at home, what if they have a bad dog, what if they dont want to borrow the trunk... and ended up throwing a rock through a window in the house and yelling "pitäkää tunkkinne". 

Anyway, I have amazed several sensor manufacturers by asking them to first send me the CANopen manual and not their marvellous product. 
By reading the manual one can say pretty much about the company, implemenatation and understanding of CANopen. 
When manual sucks (like in this case) one really NEEDS to use the product in order to continue the discussions. 
I have seen couple of commercial manuals which made me feel sick. 

isto 
btw, nice game on sunday.

Hello John, 
I am aware of this manual. 
Look at page 823, chapter "6.16 CAN". 
Only two pages describing CAN. Definitely not enough information. 

Regards
