Этот пример показывает вам, как считать данные о канале из MDF-файла.
Прежде, чем считать данные о канале из MDF-файла, открытого доступа к файлу с mdf команда.

read команда используется, чтобы получить данные от MDF-файла с несколькими изменениями. Требуется два первичных аргумента. Каждый - числовой индекс группы канала, из которой можно читать. Второй имя (имена) каналов в группе канала, чтобы читать. Информация об этих элементах доступна от MDF-файла.
