Further, when using semi-colons, if there are commands of the same command level, the root command can be
omitted.
<Ex.>
Due to there being a command within the same level, everything after CONTain is executed.
ALM:CLEar;CONTain:CC <NRf>
When a colon " : " is detected in the program message, the command level is moved to the next level. If a colon
" : " is detected right after a semi-colon " ; ", the pass pointer is reset to the root level. If there is no colon after a
semi-colon to connect the characters, the root is interpreted to be omitted. If there is a colon after a semi-colon,
then the root is interpreted to be reset.
<Ex.>
Due there being no colon after the semi-colon, the command level for everything after the semi-colon is
interpreted as ALM:. Since there is no ALM command after ALM:, it is interpreted as an error.
ALM:CLEar;ALM:CONTain:CC <NRf>
Common Commands can be inputted so that they are not affected by the SCPI Command’s pass pointer.
Further, pass pointers also will not be affected by Common Commands.
<Ex.>
ALM:CLEAR;*IDN?;CONTAIN:CC?
Delimiter
Please attach any of the following to the end of the program message; CR/LF/CR+LF (CR:Carriage
Return(0x0d), LF:Line Feed 0x0A).
Executing Commands
Commands will be executed in the order in which they appear in the program message.
Invalid commands are interpreted as errors and will not be executed.
If valid and invalid commands are included in a multi-command program message, valid commands will be
executed immediately before invalid commands are detected. Everything after an invalid command is ignored
even if it includes valid commands.
<Ex.>
Everything up to ALM:CLEar is a valid command so it is executed; everything after becomes an invalid
command and is ignored.
ALM:CLEar;:ALM:CONTain:CC <NRf>
Assigning Device Address
All program messages being received are ignored if the device address is not assigned.
The device address only needs to be assigned once, once assigned it can be omitted.
<Ex.>
The device address is assigned to 1 for the first time, all commands then after are executed for the device
address 1 HX-S-G4 power supply.
ADDRess 1;:ALM:CLEar;CONTain:CC <NRf>
ALM:CONTain:CV?
Acknowledge Message
When a normal command is received, returns "OK". When an abnormal command is received, returns "Error".
Settings can be set, via command, so that no return is received when normal.
(When receiving QUERY commands, the response message becomes the Acknowledge Message.)
