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

[Christoph Schroeder]

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

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



Best regards,

Ian

Subject: [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
