Appendix F: Command and Request Reference
Command Reference
A command sent to the 651 unit instructs it to perform a task or change a setting. Commands are
grouped into two categories: control commands and parameter commands.
Control commands directly control the actions of the valve. Valve open, valve close, and valve
halt, as well as selection of the controlling set point, are examples of control commands.
Parameter commands determine the settings used by the 651 controller. Set point levels,
softstart rates, and sensor full scale are examples of parameter commands.
Note
To conserve space, the ENTER key is not included in the request
messages listed the following tables. You must press the ENTER key to
send the request message to the 651 controller.
Enter commands without spaces. Spaces are used in the manual to
improve readability.
RS-232 command syntax is shown in Table 26, page 128.
