Experimental Physics and
Industrial Control System

Hi again,

Still trying to run down some more details about talking to these lovely Keysight boxes via EPICS.  I've got the stock SCPI stuff working, so next I wanted to read some resistance values.  I added this to my protocol file: 

getResistance {
    out "measure:resistance? \$1,\$2,\$3";
    in "%E";
}

And added this to my .db file:

record(longin, "$(P)$(R)GetIG")
{
    field(DESC, "Get Alphatross Ion Gauge Value")
    field(DTYP, "stream")
    field(INP,  "@devswag6.proto getResistance(10,0.1,(@5012)) $(PORT) $(A)")
}

After starting the ioc, I can do ' dbtr swag6testGetIG`, which sends the correct string, and gets a reply from the mainframe.  What I'm stuck on is handing the reply.  The box replies with:

 +9.90000000E+37\n

But the way I have things configured I get:

2023/01/24 12:49:07.000698 LAN0 swag6testGetIG: Format "%E" has data type double which is not supported by "swag6testGetIG".

It seems like that should work, based on: https://paulscherrerinstitute.github.io/StreamDevice/formats.html  
I don't know if I managed to compile StreamDevice with some missing library, or if I've done something else wrong along the way.  

Thanks for any pointers,
     Greg
