2.1.4 Recorder Responses
The recorder returns the following responses to commands.
• If the recorder successfully completes the processing of a received output request
command, it outputs the requested data.
• If the recorder successfully completes the processing of a received command that is not
an output request command, it outputs an affirmative response.
• If a command syntax error, setting error, or other error occurs, the recorder outputs a
negative response.
For each command the recorder receives, it returns a single response. The controller (PC)
side must process commands and responses in accordance with this command-response
rule. If the command-response rule is not followed, the operation of the recorder is not
guaranteed. For details on the response syntax, see 2.9 Responses to Commands.
