GPIB DC power supplies and DAQ with two controller

have 6 stations connected with 6 dc supplies and 1 DAQ with GPIB. I plan to shut down 1 station and connect with new computer and test new function. I am using to VBA to control the stations now. From DAQ, Can I connect two controllers over GPIB. If this is the instrument to get the signal from it, I know it is okay to connect parallel but not sure the controller(computers)

From what I can tell so far, you should be able to disconnect the device and connect it to another computer. However, some more information would be useful:

 

What DAQ device are you using?

Why do you want to use two computers?

Are you trying to connect them at the same time, or are you unplugging the cable from one computer and plugging it into the other?

I am using 34970A Aglient DAQ

 

Because we are going to change to new computer based on Window 10, I need to transfer and modify the program based on Window 10. 6 stations are running so my plan is shutting down one station and disconnect the communication. I attached a picture with explanation. I plan to connect one more cable over DAQ GPIB Port.

 

Another question : I just want to make sure. I do not have a driver for dc supplies(can't find neither because it is too old one) but as long as I can find VISA address, I can control with SCPI command. is that right? 

 

Thank you Conner

I don't see any issues unplugging your current setup and plugging it back into a new computer. As long as you can communicate serially with the devices (through NI-VISA) then you can send and receive commands without a specific driver. Device drivers are just easier to use and more user friendly.
