[etherlab-users] How to check if all slaves have reached operational state?

Dear EtherLab users,
After activating the master and starting frame exchange, is there a way to
check whether all states have reached operational?
*Additional info:*
Currently, in my code
<https://github.com/mohse-n/L7N_EtherLab/blob/master/simple_test.c>, I just
send empty frames for long enough (trial and error) so that when I exit the
loop, my slaves (servo drives) are in OP state.
I have tried checking the working counter in the loop and exiting from it
after the domain's working counter becomes equal to our expected value.
However, there is still a small delay after that happens and the second
slave reaching operational state.
Best,
Mohsen

Would user command from OS console give you the answer:

***@xxxxx<mailto:***@xxxxx::~$>::~$<mailto:***@xxxxx::~$> ethercat slaves



The ethercat commands can be used while your application is running. Try 'ethercat --help' for other options



Best regards,

Ian

Hi Mohsen,

additionally you can use ecrt_slave_config_state in your application. I call this function plus ecrt_master_state and ecrt_domain_state every other second to check the status of the whole setup.

Best regards,
Christoph
