Do a search on RS bias resistor on the NI sites and you should get a document that explains about this. Can anyone give me eurotberm hand? Message 5 of 6. Also, I am thinking if the issue is due to the incorrect serial port I am using. I hope this information will help you make your system work. Also, just wonna make sure that whether the serial port I am using is compatible. The REM should flash when there is a connection however I cant get it flash so I assume the problem is in connection.
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?
Now Eurotherrm have a strong suspicion that the Eurotherm driver you downloaded was actually developed and tested with a controller with RS interface. 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. Is it really necessary for me to use the serial port from NI instead of using random brand serial port?

Eurotherm et3500 Controller
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. I also spent quite a bit of time for setting up Eurotherm RS Comm.
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. Most Active Software Boards: Message 3 of 6. Another solution we also euurotherm used was to place an Eurotherm KD converter between the RS interface on the computer and the RS interface in the Eurotherm controller.
Message 1 of 6. This was not possible to get working although I didn’t have a chance to go very deep into debugging with this.
On software configuration, here is the list. What did work is to replace eurtoherm 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.
With this configuration, I made it work. Message 2 of 6.
I found that terminal registor cause significant voltage drop, so I do not use any termial registor. Unless your interface card has these resistors built in, it is likely the problem why you can’t get this work. However time and other constraints did not allow us to debug that deep enough to make it work as a full RS connection.
I encounter a problem with my project.
