[etherlab-users] EtherCAT newbie - NXIO 100-RE

[Fuchs Clemens]

thanks for your advice!
You were right, I mixed up VendorId and ProductId.
I'm now able to write data to the board.
But when registering the second PDO of the board to the domain, neither writing nor reading is working.
The ethercat datagramm contains the correct output data but the slave is doing something strange.

Do you have any idea, what could cause the problem ?

thanks,
Clemens

I don´t know what you did in your code inbetween but i think that you swaped the Vendor ID and the Product ID in your define of #define NXIO_100RE.
And i am not sure if your sync manager configuration is right { 0, EC_DIR_OUTPUT, 4, nxio100_pdos }, shoud be { 0, EC_DIR_OUTPUT, 1, nxio100_pdos } in my opinion.

Double Check the hole programm. Maybe wrong indexes cause the problems.

When i had to write the sii i use a demo version of TwinCAt (30day evaluation) available on the Beckhoff site.

Regards

Christian


Maybe this is the reason for not getting the slave to operational state.
