hii baskar,

As you told me 3 sreps I tried that also but still I am getting same error that VISA:(Hex 0xBFF0015) time out expired before operation completed.

when I try to run my program then remot light of my powersupply ll be on means i can connect with my powersupply but after some time I got the error message as I wrote above.

I also varify my program with example which is given by Labview in tools and find example then  serial in that advanced serial write and read.vi.

in first attampt I got same error  VISA:(Hex 0xBFF0015) time out expired before operation completed,but in secont time I got the reading string from my instrument.

samething I also tried in my open visa test panal and in that INPUT/OUTPUT in first attampt i got same error and in sencond attampt I got success.

now I am confuse why is happen like this.

here I am attaching that photo in which i got error in initialize.vi.

and will you please tell me again that how can i put delay and where exactly i have to put it to remove this error and sorry for asking again becasue I am new so i didnt get it directly.

thanks in advance.

Hi akki,

           For giving time delay,Right click in block diagram -->programming-->timing-->timedelay icon and give time in that icon and place between write and read Icon  it will create delay in your program.Try to run the program with enable the bulb (near to stop button)

           Cool, we try to solve this problem.where can u get driver for your power supply?.I thought you are getting wrong driver for your power supply.I searched in NI Support there is no driver for your power supply.you already refered link is correct (http://digital.ni.com/public.nsf/allkb/874B379E24C0A0D686256FCF007A6EA0)that is the correct way to solve this problem.You already solved but you have another error right ? that error depends upon wrong driver for your instruments.If you have the driver please send me 

but you are having the same error when you are not connecting with instruments also ,so better you can check the baudrate,parity,stopbits,flow control and databits for your serial port.

cheers,

baskar

Dear akki,

              unfortunately u r taking wrong driver i already told u for your instrument have no labview drivers.your model no is HMP 4040 then y u take HM 1004-3 driver actually u r taking oscilloscope drivers just go through this link http://www.hameg.com/hm1004-3.0.html?&L=elivwdhzmrtojgpg&0=

In this link http://www.hameg.com/drivers.0.html?&no_cache=1 each and every model number is different instruments.unfortunately u dont have driver for your instruments. 

In labview each and every instruments have unique drivers we are not able to use other driver with out any modification.
