CK3E EtherCAT Acontis - howto accomplish bus shift mode


Recommended Posts


I run CK3E ( with 2 Omron 1S-drives (Rev 10001). In master shift mode it's fine.


Howto accomplish bus shift mode?!

Why still do I have to set "ECAT[0].DCRefMaster=1" after loading Mapping to PowerPMAC?!


What I do (without success)

1. set Clock adjustment to bus shift

2. Click "Load Mapping to PowerPMAC"

3. Set using terminal "ECAT[0].DCRefMaster=1" (where point 2 let it at 0)

4. Clicke "Activate EtherCAT"


Why wihtout success:

The drives would run in CSP, but reading the slaves register 0x92C would give for the first slave steadily 0 (!) and for the second slave <>0. Both should deliver <>0 values in case of bus shift mode.


Regards, Anton

Thanks Steve!


I upgraded using IDE V4.3.2.19 from V2.5.0.3 to V2.5.4.0 - and lost gpascii and other stuff - no connection to ppmac anymore. Serially I can still conect. /opt/ppmac only shows usrflash and usrflash.x directories, nothing else anymore.


So how to successfully upgrade from V2.5.0.3 to V2.5.4.0 resp reinstall the lost directories?!

I could recover and successfully install V2.5.4.0, thanks to great support from Lucien / ODT Switzerland.

Looks like the device-tree "ls1021a-twr-ck3m.dtb" wasn't updated at all.


Anyhow, now bus shift mode seems to work fine.
