If <delay> is set to less time than is required for the Input + Update +
Execute Algorithms phases, ALG:OUTP:DELAY? will report the time set, but the
effect will revert to the same that is set by ALG:OUTP:DELAY 0 (Output begins
immediately after Execute phase).
·
When <delay> is AUTO, the delay is set to the worst-case time required to
execute phases 1 through 3. This provides the fastest execution speed while
maintaining a fixed time between trigger and the OUTPUT phase.
·
To set the time from trigger to the beginning of OUTPUT, use the following
procedure. After
defining all algorithms, execute:
ALG:OUTP:DEL AUTO sets minimum stable delay
ALG:OUTP:DEL? returns this minimum delay
ALG:OUTP:DEL <minimum+additional>
additional = desired - minimum
Note that the delay value returned by ALG:OUTP:DEL? is valid only until
another algorithm is loaded. After that, it is necessary to re-issue the
ALG:OUTP:DEL AUTO and ALG:OUTP:DEL? commands to determine the new
delay that includes the added algorithm.
·
When Accepted: Before INIT only.
·
*RST Condition: ALG:OUTP:DELAY AUTO
ALGorithm:OUTPut:DELay?
ALGorithm:OUTPut:DELay? returns the delay setting from ALG:OUTP:DEL.
Comments
·
The value returned will be either the value set by ALG:OUTP:DEL <delay>or
the value determined by ALG:OUTP:DEL AUTO.
·
When Accepted: Before INIT only.
·
*RST Condition: ALG:OUTP:DEL AUTO, returns delay setting determined by
AUTO mode.
·
Returned Value: number of seconds of delay. The type is float32.
ALGorithm:UPDate[:IMMediate]
ALGorithm:UPDate[:IMMediate] requests an immediate update of any scalar, array,
algorithm code, ALG:STATE, or ALG:SCAN:RATIO changes that are pending.
Comments
·
Variables and algorithms can be accepted during Phase 1-INPUT or Phase
2-UPDATE in Figure 6-1 when INIT is active. All writes to variables and
algorithms occur to their buffered elements upon receipt. However, these changes
do not take effect until the ALG:UPD:IMM command is processed at the
beginning of the UPDATE phase. The update command can be received at any
time prior to the UPDATE phase and will be the last command accepted. Note
that the ALG:UPD:WINDow command specifies the maximum number of
