CANopen and Microbasic

Hello,

I'll fastly present myself and my project. I'm a student in computer science and currently in work placement. I'm working on many of Roboteq controllers and i need to create the bus CAN to permit communication between controllers.

I read all the documentation about Digital Motors Controllers, and i successfully implement the communication with RawCAN and MiniCAN with two controllers (XDC2230 and MDC2230). But i really don't understand how to use CANopen in my Microbasic script. MiniCAN use TPDO and RPDO for read/write, it's the same use with openCAN ? And how work SDO message ? Can u please give me a short example on how to use CANopen with Microbasic script ?

Thanks for help.

PS : Sorry for my bad english, I know that I need to train it !

Our controllers can only initiate TPDOs and receive RPDOs. SDO and Network Managment require that there is a CANOpen master.

If you are only going to use roboteq controllers, we recommend you use the other protocols that are simpler and more efficients. RoboCAN is our newest and easiest to use. See dev.roboteq.com/dev1/index.php/technology-menu/296-robocan

Hello,

Thanks for your answer. I'll compare advantage/disadvantage for each protocol and look at RoboCAN.
I have an other question, not really with the origin subject. In first, i used SDC2130 Controller, but i find that this kind of controller are not compatible with CAN, are you working on it or they never will be compatible ? A lot of device in my company have this controller, so it's a problem for me.

Thanks again !

Edit : Mmmmh.. I don't understand how a controller can listen many controller. In the configuration, i can just enter one ID. We can't make a list of ID ?

Hi,

Thank you for your interest.
Nevertheless i think that you didn't understand me when i speak about "Node ID", i want to know if we can listen just 1 ID or if we can do a list of them. (If we can do a list, how ?)

Example : 3 controllers (A, B & C). The A controller want to listen B & C. is it possible ?
