RS-232 Commands and Requests Chapter Six: Remote Operation
62
Commands Sent from the Computer to the 651 Controller
Table 26, page 128, lists the syntax for RS-232 commands. Commands are not case sensitive. If
a command requires user-supplied parameters, it is not necessary to type a space between the
command and the parameters. In the table, each command is separated from parameters with an
optional space for clarity. For example, the S1 command to assign set point A a value of 20 is
shown in Table 26, page 128, as:
S1 value and the actual keys pressed would be:
S120 ENTER
If you choose to use an optional space for clarity, the actual keys pressed would be:
S1 20 ENTER
Note
When sending any message (command or request) to the 651 controller,
you must finish the message by pressing the
ENTER key. This appends a
carriage return-line feed to the end of the message. Use your
communications software to configure the end-of-line delimiter as a
carriage return-line feed.
Requests Sent from the Computer to the 651 Controller
Table 27, page 134, lists RS-232 request and response messages. Requests are not case
sensitive. You do not supply additional parameters with requests. For example, the R1 request
to respond with the value of set point A is shown as:
R1 and the actual keys pressed would be:
R1 ENTER
