Здравствуйте! помогите разобраться. на одной линии rs-485 собраны несколько устройств и при подключении определенного (мультизонный адаптер airzone для канального кондиционера) отваливается другое(ие) (шлюз EBUS-MODBUS NEVOTON BEG-3.1.1-W) причем шлюзов 3 штуки и отваливаются они одновременно. По отдельности эти устройства на этой шине работают стабильно. настройки modbus для все устройств 19200/E/1
Добрый день! А что значит отваливаются?
Пожалуйста включите отладку в настройках Serial и покажите логи.
По описанию очень похоже на устройство, которое неспособно быстро отвечать, как тут:
Но все же логи нужны.
Вечером буду на объекте, проверну все манипуляции с логами
на первом порту airzone, на 8,9,10 - шлюзы невотон

Либо проблема с шиной (неконтакт, отсутствие земли или два устройства с одним адресом, для ошибок CRC характерно.
Включите Debug для serial, будет виднее.
так вот же ж вывод из дебага, или я что-то неправильно делаю?
Это просто журнал. Debug режим выдает больше информации.
И да, попробуйте для начала все же увеличить таймауты.
таймауты с 1000 поднял до 15000 - не помогло.

Физика. откуда-то берутся посторонние байты. Смотрите на шину, особенно проверьте чтобы по Gnd проводу шины не было постороннего тока. Ну и защитное заземление на устройствах проверить надо.
