Hi Matthieu,
To stop writing I set a flag when the operational state was reached and the LED
was on.
I suspected it might be the watchdog timeout, since I saw that mentioned
somewhere, but
I didn't find it in the documentation. Now it makes sense.
So is the usual way of doing things to have a cyclic routine that always writes
the same
values (assuming they haven't changed)? And how do you set watchdog_mode to
EC_WD_DISABLE?
Thanks,
Allan

Hello Allan,
What do you mean by `stop writing`, stopping the cyclic task?
Slaves usually drop off OP state if they stop receiving frames, yours
might default itself to an Off state that could explain the issue.
Try explicitly setting the watchdog_mode to EC_WD_DISABLE in your
sync_info_t.

Hi all,
I'm new to EtherCat and EtherLab and I modified examples/user/main.c to
work with the devices I have for testing: (EK1100, EL2202, EL1252, EL2252).
Everything works and the LED I attached to the EL2202 turns on and off,
however the code is using a timer and constantly setting the output
value to 1 or 0 (on or off).
Why can't you just set the value to 1 once and have the LED stay on?
Even if I wait until the slave reaches the operational state, the LED
just blinks once when set to 1,
but doesn't stay on, unless the value is constantly updated. What am I
missing?
Thanks,
Allan
