Hi Andrew W.:

 

If you do not want to hack “streamReload”, you may try this: https://github.com/NSLS-II/elauncher

 

It is an EPICS device support for easy script launcher: one can run a Python (or shell, or anything you can use in a Linux terminal) script inside an IOC through a bo record. Michael Davidsaver developed it at NSLS-II a few years ago, specifically for use cases like yours.

 

You can change how fast you want to execute your script by simply changing the field of SCAN either from a command caput or from a CS-Studio button:

 

caput elauncherTestShell.SCAN 3

caput elauncherTestShell.SCAN Passive

 

caget -d GR_ENUM elauncherTestShell.SCAN

elauncherTestShell.SCAN

    Native data type: DBF_ENUM

    Request type:     DBR_GR_ENUM

    Element count:    1

    Value:            1 second

    Status:           NO_ALARM

    Severity:         NO_ALARM

    Enums:            (10)

                      [ 0] Passive

                      [ 1] Event

                      [ 2] I/O Intr

                      [ 3] 10 second

                      [ 4] 5 second

                      [ 5] 2 second

                      [ 6] 1 second

                      [ 7] .5 second

                      [ 8] .2 second

                      [ 9] .1 second

 

 

Cheers,

Yong
