Use EtherCAT DWORDS instead of Bytes

[Ibrahim Stracey]

Good Morning,

I managed to get my EtherCAT gateway up and running with my PLC, but the issue I seem to be having is that I can't change the TX/RX on Pictory to use DWORDS instead of Bytes. I'm clearly missing something simple but I can't seem to figure it out. Any help would be very appreciated.

Thanks,

Ibrahim

Hi Ibrahim, you have to use four bytes instead if you want to transfer a DWORD. The byte order is in the little-endian format.

Hi Dirk,

I'll try that. I assume that means changes to the PDO mapping on my PLC side? I'll have a go at it and see if I can get it to work. Thank you!
