This page describes how to set and get control system values via rudimentary AIDA command line tools. Be sure to set up your aida environment before attempting to use these tools.
Fetching Values: aidaget
The utility program named "aidaget" takes one mandatory argument (the name of the target); several optional parameters control how it operates. You can specify "-help" as a parameter to see simple options. Some of the more interesting options are specific to each data-provider, which may support optional or require mandatory paramters.
The following example retrieves history data. It illustrates how you can specify data provider parameters (in this case STARTTIME and ENDTIME) and control output format (-format=columns -labels):
clarrieu@tersk08>aidaget HR81:CAV2:VACM//HIST.pepii -format=columns -labels \
"-params=STARTTIME=02/01/2003 12:20:00;ENDTIME=02/01/2003 12:40:00"

1.928914E-9 01-Feb-2003 12:21:18 0 1044130878
1.928914E-9 01-Feb-2003 12:24:00 3 1044131040
As you can see, data provider parameters are specified as -params=NAME=VALUE;...;NAME=VALUE;. Note the need to enclose embedded whitespace within " marks to prevent the shell from treating it as a boundary between strings.
Setting Value: aidaset
The utility program named "aidaset" takes at least two mandatory arguments (the name of the target and the desired value; several optional parameters control how it operates.
