We primarily host it for convenience. 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. Message 6 of 6. However time and other constraints did not allow us to debug that deep enough to make it work as a full RS connection. Message 2 of 6. Also, just wonna make sure that whether the serial port I am using is compatible. What did work is to replace the RS interface in the controller with a RS module and connect it to an RS port on the compactFieldpoint.

Message 5 of 6. Or should I buy the serial protect from NI?
Applications Engineering National Instruments. Thanks for the reply The loopback works well and the LabVIEW driver I am using is directly downloaded from NI website et24xx so it can be assumed that the problem is not on the code?
Message 1 of 6. I found that terminal registor cause significant voltage drop, so I do not use any termial registor. Rolf Kalbermatter Averna BV. Instructions for that are here: 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. 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.
Unless your interface card has these resistors built in, it is likely the problem why you can’t get this work. With this configuration, I made it work. The REM should flash when there is a connection however I labvlew get it flash so I assume the problem is in connection. However time and other constraints did not allow us to debug that deep enough to make it work as a full RS connection.
Message euurotherm of 6.
Eurotherm et24xx Controller
Also, I am thinking if the issue is due to the incorrect serial port I am using. This was not possible to get working although I didn’t have a chance to go very deep into eurootherm with this.
Can anyone give me a hand? 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.
Eurotherm nanodac Controller
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. I hope this information will help you make your system work. Now I have a strong suspicion that the Eurotherm driver you downloaded was actually developed and tested with a controller with RS interface.
Message 3 of 6. Also, the et24xx driver maybe shouldn’t be assumed to work. Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type.

What did work is to replace the RS interface in the controller with a RS module and connect it to an RS port on the compactFieldpoint. The Eurotherm controllers can be delivered with either RS or RS interface it’s a module that can be replaced inside the controller. I also spent quite a bit of time for setting up Eurotherm RS Comm. Also, just wonna make ejrotherm that whether the serial port I am using is compatible. On software configuration, here is the list.
I encounter a problem with my project. Eurltherm Active Software Boards: 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.
Message 4 of 6. Message 6 of 6. Is it really necessary for me to use the serial port from NI instead of using random brand serial port?
