4.3.4 PROGRAM MESSAGE STRUCTURE
SCPI program messages (commands from controller to power supply) consist of one or more
message units ending in a message terminator (required by Kepco power modules). The message
terminator is not part of the syntax; it is defined by the way your programming language indi-
cates the end of a line (such as a “newline” or “end-of-line” character). The message unit is a
keyword consisting of a single command or query word followed by a message terminator (e.g.,
CURR? or TRIG). The message unit may include a data parameter after
the keyword separated by a space; the parameter is usually numeric (e.g., CURR 5),
but may also be a string (e.g., OUTP ON). Figure 4-2 illustrates the message struc-
ture, showing how message units are combined. The following subparagraphs explain each
component of the message structure.
NOTE: An alternative to using the message structure for multiple messages defined in the fol-
lowing paragraphs is to send each command as a separate line. In this case each
command must use the full syntax shown in Appendix B.
