Re: printing value of pv to new line

[Hugo Slepicka <hhslepicka@gmail.com>]

Hi Palak,

Don't do that in a BOY script. It’ll be executed on the UI thread and cause the UI to freeze.

There are plenty of other ways to do this operation, e.g., run a python code outside of CS-Studio to do it.

I want to export the pvs without archiver. I want to export the pv datas only when I make a button true. Hence I want to use the script. Please can you help me with it.

Hi Palak,

You need to indent your code inside the while loop.

As mentioned a while ago here on the list, if you do this inside CS-Studio you will probably freeze the entire UI.

What are you trying to do? Maybe in this case you could use the Archiver and export your PV values later.

Cheers,

Hugo

I want that my pv should be read and printed continuously. I have written below python code :

from org.csstudio.opibuilder.scriptUtil import PVUtil
import os,sys
import subprocess
import glob
from os import path
from datetime import datetime
while True:
pv=PVUtil.getDouble(pvs[1])
i = datetime.now()
sys.stdout=open("test2.txt","wb")
print str(i), pv '\\n'
sys.stdout.close()

But I an getting error:

SyntaxError: ("mismatched input 'pv' expecting INDENT", ('<script>', 8, 0, 'pv=PVUtil.getDouble(pvs[1])\n'))

please help me to solve this
