sp field number
This command reports the variable number and name stored at the index in
the scratch pad list.
The scratch pad is a temporary memory area which is used to set up lists of
selections for lrec, srec, or streaming data items. The user can copy any of
these lists to the scratch pad, modify individual elements in the list, then
save the scratch pad back to the original list.
The following example shows that field 1 in the scratch pad is set to index
number 3, which is for the variable PM concentration pressure.
Send: sp field 1
Receive: sp field 1 3 PM
set sp field number value
number = 1-32 for lrec and srec lists, 1-8 for streaming data lists
This command sets the scratch pad field number (item number in scratch
pad list) to value, where value is the index number of a variable in the
analog output variable list. Available variables and their corresponding
index numbers may be obtained using the command “list var aout”. The
“set sp field” command is used to create a list of variables which can then
be transferred into the lrec, srec, or streaming data lists, using the “set copy
sp to lrec”, “set copy sp to srec”, or “set copy sp to stream” commands.
Send: set sp field 1 34
Receive: set sp field 1 34 ok
stream per
This command reports the current time interval in seconds for streaming
data. The following example reports the streaming period is set to 10
seconds.
Send: stream per
Receive: stream per 10 sec
set stream per number value
number value = | 1 | 2 | 5 | 10 | 20 | 30 | 60 | 90 |120 | 180 | 240 | 300 |
This command sets the time interval between two consecutive streaming
data strings to number value in seconds. The following example sets the
number value to 10 seconds.
Send: set stream per 10
Receive: set stream per 10 ok
