Hi,
we have to develope a software for our lab, but we are beginner with LabView.
To acquiring the data from eurotherm 2704 we installed the iTool OPC Server and changed the file from
http://www.eurotherm.com/products/controllers/2704_doc.htm
site, after that it was possible to read / write the temperature from the controllers.

it works well,
but we have an other problem now. The connection between the PC and the controllers is too slow. We have 3 controllers (with 3 loops each). To write 9 values and to read 9 values are ca. 3 seconds needed, and it is to slow for our project.
We changed the timeout of the serial-port to 200ms (it is the minimum value), through it the update-time is decreaded to 2 seconds (1 second would be enough for us), but we are not sure, that it is ok, to change the timeout-time of the serialport.
By the changing of the timeout-time (in the iTools OPC Server software) of the devices the update-time stayed the same (we think so).
(What does the timeout of the devices do ? )
It is possible to do the update faster ?!
We attached the simplified version of the program (only the part, where the values are read / written).
Maybe we have a mistake in other code, or it can be done better ?
We hope, you can help us.
Thank you very much.
