PyModbus asyncio copier - невозможно перезапустить копию после повторного подключения

Question

Я изменил PymodBus Asyn c Пример клиента Asyncio и создал программу (см. Ниже) для копирования катушек и регистров из одного PL C в другой. Для каждого узла есть основной поток и поток (PL C). Модифицированный код работает неплохо. Но я не могу перезапустить копию после того, как мой клиент отключился / повторно подключился к серверу. Что мне нужно сделать? Спасибо!
