4.2 Messages and Terminators
This section describes the terminology used in this operation manual
concerning the communication between the computer (controller)
and the KJM6310 (device).
4.2.1 Messages
Program messages refer to instructions sent from the computer to the
KJM6310. Response messages refer to responses sent from the
KJM6310 to the computer. Program messages can be divided into
command messages, which execute certain functions of the KJM6310
or change settings, and query messages, which query the settings of
the KJM6310.
To notify that the processing of a message is complete, the KJM6310
sends a response message to the computer (referred to as an acknowl-
edge message) in response to each program message sent to the
KJM6310. Below are the messages sent by the KJM6310.
When a command message is sent
“OK” is returned upon successful completion.
“ERROR” is returned when an error occurs (syntax error for
example).
When a query message is sent
A response message for the query is returned upon successful
completion.
“ERROR” is returned when an error occurs (syntax error for
example).
A space (ASCII: 20 h) is required between the command program
header and data.
4.2.2 Terminator
The message terminator indicates the end of a message. Use CR
(ASCII: 0Dh), LF (ASCII: 0Ah), or CR+LF (ASCII: 0Dh, 0Ah) for
the command message terminator.
Use CR+LF (ASCII: 0Dh, 0Ah) for the query message terminator.
