Canopen using can

[can can canopen]

Hi all

I am working in Canopen,In Canopen there are some index and subindex in which they are password protected.I can read the but not write into that parameter. I am unware of what password is .

Is there any method to write into that parameter using CANopen??/

I have one more doubt, password can be implemented in application level and not in physical layer and data  layer where CAN functions are used.

Can i read a parameter for example index 2030h and subindex 2d using CAN frame api .

If this is possible then how to achieve this.

Please guide me.

Hi,

Writing to a sub index is typically not password protected, but these sub indexes are either write and read or readable only. Look into the manual of your device for more information. And if you want more guidance, please post the manual, so we can see what Object Index h2030 means and how it is implemented.

Hi Dirk

Index 2030h was just a example, actually that is RO parameter. I will attach the Object dictionary where it is mentioned that parameter is password protected.

Can you tel me how to read data using CAN frame API, index 2030h and sub index 2.

Thanks and regards

Hi Dirk

I am attaching the Object dictionary, I have highlightened the password sentence please go through this.

Here in the first page they mention about Password to unlock certain parameters.

You should buy the CANopen LabVIEW Library if you have LabVIEW available.

Otherwise there are more then one post available for how to use the frame api for CANopen Communication.

To figure out this p[assword thing you should call the manufacturer directly. I have never seen such a locking mechanism with CANopen.
