Реализованы кольцевая запись CAN-команд, дискретных сигналов, уставок и состояния ЦАП, а также отдельный архив отключения с секундой постинтервала. Добавлено расширение Modbus для онлайн-графиков и чтения архива через SetGUI. Сохранены управляющая логика и существующая область технологических регистров. Добавлены русские комментарии, описание протокола и тест регистратора. Проверка алгоритма и синтаксиса C пройдена; сборка TI/CCS и испытания на плате ещё требуются.
