6. COMMAND REFERENCE 89
Immediate Only
Immediate only commands are:
K, R(UF), R(DF) and R(ST)
The controller acts upon these commands as soon as they are received.
Immediate or Buffered
Immediate or buffered commands are immediate unless command execution is being
delayed, in which case the command is buffered. When command execution is being
delayed whilst waiting to finish a previous command, interrogation commands can be sent
and get executed immediately. Consequently, the report of such commands as 1R(ST),
1R(UF) etc. is correct. However, if a buffered type of command is sent the buffered
command just sent and any other interrogation commands get buffered and will not report
back until the current function is finished. In this situation ‘Immediate only’ commands can
be executed.
Saved by SV
A command that has the property of being ‘saved by SV’ means data associated with that
command is capable of being stored in non-volatile memory. The saved value will become
the default value on power-up or following a Z command.
Not Saved by SV
If the command does not change data, such as K or Z, the commands’ properties are listed
as ‘not saved by SV’.
Automatic Checking of Valid Commands and Parameters
All commands and parameters are checked for syntax and parameter limits at data entry.
For example:
1BRAKE(2)
Upon entry, this will cause a *E, value is out of the valid range type error report.
