Hello!
I am trying to configure my Eurotherm 3216 PID Themperature Controller with LabVIEW. I tried to launch the examples as suggested in the Eurotherm manual "3200_AN_030908U001_1.pdf",
using the recommended Serial Configuration, however I get the following Error:
"Error - 1073807339 occurred at Visa read [...] VISA: (Hex0xBFFF0015) Timeout expired before operation completed."
I get the same error when testing the port through the "Continuous Serial Write and Read.vi", and also when testing it through the NI-MAX VISA Test Panel by attempting to read "*IDN?\n". On the other hand, I am able to communicate with the device through the same port using the software "iTools Engineering Studio", so I am puzzled. I read the vast material available about the same error in the forum but was not able to solve the problem, therefore some additional help would be extremely appreciated. I am not even sure it is a LabVIEW issue.
Thank You All and Best Regards,
Matteo

I don´t think *IDN? is in the programming, I just thought that it is something that I could write and then read back again from the NI-MAX VISA test panel to check communication with the device. I am using the examples provided by the Eurotherm together with the driver, but I get the error.

Hey Matteo,
have you already looked at this?

Eurotherm has their own drivers for this device.
Since I need to register to get anything from their website, I won't be getting any further with this.

Dear All,
I cross tested the device with another computer, using the same communication settings, same Eurotherm driver, same wiring, and it worked. It sounds a bit like magic to me.
Thank You for the support,
Matteo
