Два MSWv3 и MWAC висят на первом порту, третий MSWv3 и MRM2-mini - на втором.
На первом порту также висит MAP3H, на втором - MR14 и ардуина. С них ошибок нет.

Все устройства подключены неэкранированной витой парой, подключение шиной.

В принципе, эти ошибки особо ни на что не влияют, регистры в итоге прочитываются. Но немного напрягает и хотелось бы от них избавиться.

Что пробовал менять:

  • у порта

    • Response timeout - 1000
    • Desired poll interval - 100
  • у устройств

    • Desired poll interval - 100, 300
    • Delay before accessing the device - 100
    • Interval between register reads - 1000
    • Frame timeout - 10

Все это в разных комбинациях у разных устройств. Не помогло.

Собственно, вопрос - можно ли что-то еще сделать/подкрутить?

хелп!

Извините за задержку, болеем.
Первое, на что стоит обратить внимание – на качество шины, какой длины она у вас, как соединены линии в клемниках. Измерьте напряжение на каждом из устройств – не слишком низкое? Какая скорость шины?
Попробуйте методом исключения посмотреть связь с каждым устройством по отдельности, отключая остальные.

Все модули питаются от контроллера. Напряжение на контроллере - 25-25.2V

Напряжение на всех трех MSWv3 в районе 24.63 - 24.83V
На MWAC - 24.4-24.7V
На MRM2 - 24.9-25.0V

Скорость шины везде 9600.

По длине линии - до MSWv3 - 5 метров, 10 метров и 20 метров.
До MWAC - 3 метра.
До MRM2 - 25 метров.

В клемниках все вроде надежно затянуто.

Так все отсоединять не хотелось ). Ок, попробую поубирать устройства с шины.

Можете начать с отключения устройств по одному, например, возможно, одно из них нештатно работает.
