i think you are little bit wrong because of mapping... mapping is used to setup communication canal to shape which you need...
you can use legacy or mdp but there will be different temps for your program.. if you will use MDP, my profibus component will not work probably... I had to check them... but for setup purposes of communication start it is OK
but all of them will need SDOs which tells the slave how to communicate with its master ...
Hello Endian,after a lot of atempts, I am still not able to work with the servostar drives via profibus. I think I incorporated all of your hints (use of legacy mapping, sdo stuff) but unfortunately I does not work.Please, have a look. Thanks in advance, Franz
I will create non legacy mapping and update them here... It should be problem with my mapping shape .. I will load them to el6731 and double check them with my stuff

regards
here is the non legacy stuff for single axis for DC sync ... as profibus for s600 and for s300 same, I tested them on my stuff and it should work for you too, I HOPE
if not dmesg me the output and I will check it asap

Last edit: 1 year 11 months ago by endian. Reason: FORGOR THE CONFIG
After a long break, I am trying to get the EL6751 up and running. However, I am already failing to get the terminal into the Run status without a bus error.
I have currently tried to configure the terminal with Twincat (the terminal is running in Twincat).
Saving the configuration in the terminal and starting lcnc without initcmds leads to status OP but BusOff. Mapping the first PDO (1600) EL6751 is stuck in Preop.
Starting with exported initcmds lead to the status Preop. It seems that the SDO download is not possible for reasons unknown to me.
Does anyone have an idea how I can solve this problem?
I made some progress since yesterday but currently it is not working.
countless tries editing the initcmd file to get EL6751 up and running did not succeed i ended up with dmesg output "invalid input configuration" but i have no idea how to debug/fix the wrong config (Preop).
switching the ethernet cable on the fly from twincat to lcnc lead to OP-State (only PDOs are configured in lcnc, no initcmds or SDOs).
with "ethercat pdos" i can see the list of PDO entrys configured in twincat.
but some parameters like baudrate are set to 500 kbit/s instead of 1Mbit/s
changing only the baudrate parameter with initcmds sends EL6751 to Preop.
Does anyone know how to store the parameters from twincat in the backupstorage of EL6751 to avoid using the initcmds?
I thought the button in the screenshot does this but after power up the unit has a totaly different konfiguration.
