Parameters are characteristic values that are attached to commands.
Notes on Writing Parameters
• Write parameters in their appropriate order.
• Spaces around and in the middle of parameters are ignored. Exception is the character
strings that users specify.
• You can omit the setting command parameters that do not need to be changed from their
current settings. If you omit parameters, write only the delimiters.
Example: SRangeAI,0001,,,,,1800,0 terminator
• If parameters are omitted and there are multiple delimiters at the end of the command,
those delimiters can be omitted.
Example: SRangeAI,0001,VOLT,2V,,,,terminator -> SRangeAI,0001,VOLT,
2Vterminator
There are two types of parameters: predefined expressions and user-defined character
strings.
How to Write User-Defined Character Strings (Parameters)
• Enclose user-defined character strings in single quotation marks.
Example The command for setting the channel 0001 tag to "SYSTEM1" is shown
below.
STagIO,0001,'SYSTEM1'
• There are two types of user-defined character strings depending on the type of characters
that can be used.
