Labview Driver now Available for Eurotherm nanodac – New England Temperature Solutions
Applications Engineering National Instruments. Some of the NI plugin boards do have programmable bias resistors that can even be switched on and off through a VISA attribute node if I’m not mistaken. Another solution we also successfully used was to place an Eurotherm KD converter between the RS interface on the computer and the RS interface in the Eurotherm controller.
I found that terminal registor cause significant voltage drop, so I do not use any termial registor. The Eurotherm controllers can be delivered with either RS or RS interface it’s a module that can be replaced inside the controller.
What did work is to replace the RS interface in the controller with a RS module and eurtherm it to an RS port on the compactFieldpoint.
Message 1 of 6. Message 3 of 6. Most Active Software Boards: Now I have a strong suspicion that the Eurotherm driver you downloaded was actually developed and tested with a controller with RS interface.
However time and other constraints did not allow us to debug that deep enough to make it work as a full RS connection. Unless your interface card has these resistors built in, it eurtherm likely the problem why you can’t get this work.
We primarily host it for convenience. Do a search on RS bias resistor on the NI sites and you should get a document that explains about this. Also, just wonna make sure that whether the kabview port I am using is compatible. Sounds like we have quite a few different things going on here, so lets backtrack a bit and see where were getting the communication issues.

Rolf Kalbermatter Averna BV. The Labvifw should flash when there is a connection however I cant get it flash so I assume the problem is in connection. Message 2 of 6. With this configuration, I made it work. Message 6 of 6. On software configuration, here is the list.
Labvifw it really necessary for me to use the serial port from NI instead of using random brand serial port? I also spent quite a bit of time for setting up Eurotherm RS Comm. Or should I buy the serial protect from NI? I encounter a problem with my project. I hope this information will help you make your system work. Thanks for the reply The loopback works well and the LabVIEW driver I am using is labfiew downloaded from NI website et24xx so it can be assumed that the problem is not on the code?
Message 4 of 6.
Also, I eurotjerm thinking if the issue is due to the incorrect serial port I am using. Can anyone give me a hand? Instructions for that are here: This was not possible to get working although I didn’t have a chance to go very deep into debugging with this.
Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type.
The unit I got from the client to do some testing in our office appeared to be defect, and testing in the factory installation is a hassle. Also, the et24xx driver maybe shouldn’t be assumed to work.
