Hi Edwin,

So I am still getting a write error.

Hi Edwin,

Thank you for your reply. But I am relative new to codesys.
So I am not sure how to do this. I assume this can added to the EL6751 device startup parameters.
So I added a new SDO like in the picture:

But I think I am not doing this correctly:

From the log I am getting error during writing of the 8001:

Any advise on how to do this.

Hi Sander,

the problem is:

EL6731 has a new Firmware and we will adapt this to 3.5SP15 release.

The Workaround is:
Description:
Newer EL6751 firmware versions do not work (e.g. Rev.Nr. >= 0022).
Driver does not receive CAN messages.
New firmware version >= 17 need an additional CoE parameter with index 0x8001.
From Beckhoff documentation:

Index 8001 CAN Rx filter table
From firmware 17 of the EL6751, parameter 0x8001 must be written with valid values.
If all data are to be written into the CAN interface, the following must be entered:
For 11 bit and 29 bit identifiers:
0x8001: 01 00 00 00 00 00 00 FF FF FF 1F
For 11 bit identifiers
0x8001: 01 00 00 00 00 00 00 00 FF 07 00 00

Hi Edwin,

Thank you for you reply.
I have attached the codesyscontrol.log with the compile switch set and the output of the can listing device.
Hope this helps.

Thanks,

Hi,
could you set CANOPEN_DEBUG as compiler define and send the plclogger then..?

Hi All,

I have connected an an EL6751 CANopen Master to an CANopen slave device.

But I keep getting the error.

NetID 0, NodeID 1: SDO Read Timeout for object 16#1000sub16#00; AbortCode: 16#05040000

If I connect a can tap I can see the outgoing message from the CANopen master and I also see the reply from the Slave device.
But for some reason Codesys keeps retrying and doesn't see the reply message from the slave.
What am I doing wrong?

Here is the output of the CAN tap:

Any help would be appreciated.

Thanks,
Sander
