SDORead : ETC_CO_SdoRead;
SDOWrite : ETC_CO_SdoWrite;

I want to read&write SDO from ethercat slaves using these FBs.
When I write to SDO,it always fail,even I changed to write other address,such as 0x6099.Meanwhile reading always good.
But my friend use the the FBs to write another ehtercat slaves,read and wirte SDO both good.

My question:
Is it the slave's problem about write SDO error?

Hi,
do you use this example from here:

After installing this package you'll find the example here:

But I do not want to use EtherCAT Example.
Why the way I used do not work?And what is the problem?
Tks,anyway!

Did you ever find a solution to the ETC_CO_sdoWrite problem?

I have the same issue. I can read Sdo's fine, but can't write anything.
I have downloaded and using the Ethercat example from CodeSys Store.
Have tried to write with ETC_CO_sdoWrite and ETC_CO_sdoWrite4, but no luck.
With ETC_CO_sdoWrite, I get the error:
ETC_CO_FIRST_ERROR,
SdoAbort: 16#06090031, if using WORD, and 16#06070010 with DWORD as write value.
I can't find any description about the error, or errocode.

!!! Update:
It turned out the values I am writing are not within legal range.
So problem solved.

Hi Leon,
