Hey Neviile, i did try what u suggetsed and the funny thing is the valves change postion twice (i.e 2 cycles) and then the alarm goes off and i did try Karlos's idea too, but i gss i incorporated it in the wrong way and it din work, anyways gss I will have to ask someone to see my code with the device attached and debug it. Thanks guys for ur thoughts.

Thanx, Phil, Neville and Karlos for your prompt replies.I really appreciate u guys taking time off to go thru my extensively looong code:).Phil, the whole day i tried (with my limited knowledge) to make sure i closed all teh VISA ports and well i wasn sucessful.Neville and Karlos, I will try ur solutions tom and get back to u.the option Neville gave sounds pretty cool, hope it works.

HI Phil, I tried incorporating this in the larger part of the code that i had developed adn same problem, works when highlighted,I have attached my code.
there are 5 valves have 8 outlets and the dials r used to indicate which postion teh valve is currently in.

Hey I have been working on a interface to make some valves work.I have hooked up the hardware to the RS485,and com4 port of the com and I have created a code to make the valves work , however when i try checking if the valves r in the right postion (a part of the main code), it dosen work.
its like this (i am explaining ti a bit since i gss u need to know abt how the hardware works inorder to help me).
to send a valve to a postion: the code to send to teh device is
/L GO 5 (i.e u r sending valve with id L to position 5)
similarly to obatin the current positon of the valeve u have to send to the device
/L CP (i.e what is the current position of valve with id L). the output of this is
L Position = 5.
(I have attached the code that i have written to check the valve postion, bt somehow when i run the program it dosen work, however when i highlight in the block diagram page to see the program flow, then the program works)
can anyone suggest why is it so, and has anyone come across a problem where the program as such dosen work, but when u highlight it it works, and since it works when highlighted i can't even detect where the problem is, to debug it.

Warning:1073676294 occured at VISA read
Possible reasons: VISA:(Hex 0xFFF0006). The number of bytes transfered is equal to the requested input count.More data might be available.
when i incorporate this code in a larger program, it fails to run, so I was wondering if anyone can give me an insight as to how to solve this problem.
example of the program is:
write data : SN
read data : SERIAL = 87075
