Re: CSS - how to read waveform of CHARS (or STRINGS) in a script?

Hi Isabella,

I think that this will work for you:

from org.csstudio.opibuilder.scriptUtil import PVUtil

from org.csstudio.opibuilder.scriptUtil import ConsoleUtil

v = PVUtil.getString(pvs[0]).split(",")

myStr = "".join(chr(int(i)) for i in v)

ConsoleUtil.writeInfo(myStr)

HTH,

Hugo

Hi All,

In CSS (Windows), I am trying to read a waveform of CHARS inside a Python script.

When I do PVUtil.getString, I get displayed a sequence of numbers instead of characters.

Is there any way to get the text in the script??

If I create a text update widget pointing at the waveform, I get the text correctly, I want to get the same in the script.

If it helps:

for what I need to do, I can also have a waveform of strings, rather than chars, and I need to extract the strings in the Python script.

Whichever works would be fine!

Cheers,

Isabella
