I have been trying to automate my labs power supply (Createc 3504 power supply serial 598, this has a Eurotherm 3504 PID controller in it). I have isolated the power supply as a sort of experiment to make sure my labVIEW program works correctly where I connect the power supply to just a thermocouple and a resistor in series and both are connected to the createc power supply. I have implemented a program given by Eurotherm to control the temperature and when I attempt to use the program I get the error "VISA Error - 1073807339 (0xbfff0015) Timeout Expired Before Operation Completed".
I followed the trouble shooting page for this error and I believe the issue is my inputs for initializing the serial communication. After searching through the Eurotherm manual, I still cannot figure out what the unit address should be. If it is not already abundantly clear, I am new to this and I have spent many hours trying to figure this out. Any help is very much appreciated.
This is the link to the given Eurotherm temperature controller. http://sine.ni.com/apps/utf8/niid_web_display.model_page?p_model_id=2439

Check in your manual chapter 14.9.2. In there the Instrument Address is the number you want to use. By default this is set to 1.
