Hi Phil,

Another way: you can try this https://github.com/NSLS-II/elauncher .
“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.”.
A simple bo record looks like this:
record(bo, "elauncherTestCommand") {
    field(DTYP, "Launcher")
    field(OUT,  "@ps -ef | grep -i elauncher")
    field(SCAN, "5 second")
    field(VAL,  "0")
    field(ZNAM, "Name for zero")
    field(ONAM, "Name for one")
}

A more advanced module: http://mdavidsaver.github.io/pyDevSup/

Cheers,
Yong

That sounds like something that would be pretty straightforward to do with an SNL program or an asub record.

Subject: Device support of asyn port driver for system commands.

 

I would like to be able to call a system binary from an IOC record.

Something like execute a command when a BO record is set to one, or read the result of a command into a AI record, etc.  Does any one have device support or asyn port driver that might do something like this?

 

The other option I am looking at is writing something with like PCASpy or caproto.

 

Thanks,

 

Phil Sorensen
