А порой и все остальное на шине 485 отваливается.

Добрый день.
Перенес сообщения в отдельную тему, поскольку не имеют отношения к исходной.
Я вижу недопустимое количество ошибок в логе:

Расскажите как (чем) выполнена шина RS485, длину сегментов?
Какие терминаторы установлены?
Все оборудование в одном шкафу, длина шины 2 метра максимум. Терминатора нет. До обновления пару месяцев все работало отлично. Шина выполнена витой парой.
А чем выполнена и какие терминаторы?
Рекомендую выполнить проверку так: Ошибки чтения Modbus - #7 от пользователя BrainRoot
Ну и/или проверить уменьшив скорость до 9600.
Терминатора нет. Шина выполнена витой парой без экрана.
Ничего не делал(сегодня не на месте), удаленно читал журналы и … все заработало(только редкие ошибки, что как я понял нормально):

Одна-две в минуту - дав, вполне нормально.
Но выглядит как плохой контакт одного из проводов шины, в общем. Рекомендую все ж терминаторы поставить.
