Not periodic message set to peridic message

[DDoIt]

Hi,

Is it possible that the following line may be correct for periodic PDOs but not for non-periodic messages?

self.period = timestamp - self.timestamp # base.py line 301

The issues I am encountering are in some functions in the 402 profile. For example, the check_statusword function is experiencing timeout issues because messages aren't being received or transmitted.

If I remove the line above, everything works fine.

Best regards,
David

Hi @DDoIt,

The PDO is configured as periodic ??
The status word should be periodic I think...

Hi @af-silva ,
in my case the PDO is not periodic, even the statusword is not periodic. After the first call of
on_message (base.py line 294)
the PDO is defined as periodic

if self.timestamp is not None:
self.period = timestamp - self.timestamp

The .period member is reserved for use within the library, as it tells the DS402 logic whether periodic updates can be expected or the statusword needs to be polled. If you want to store that calculation result somewhere, rename your attribute to something else, or make sure the PDO actually is periodic. The latter can be done by configuring it with a transmission type that triggers with a periodic SYNC object.
