A（Answers）

In MECHATROLINK communications, the term “master” was previously used to refer to a controller or other device that sends commands, and the term “slave” was used to refer to a device that processes the commands, such as a servo or I/O device. However, these terms have been replaced with “Main Device (abbreviation: MDevice)” and “Subordinate Device (abbreviation: SDevice)”, respectively.
