LABVIEW EUROTHERM DRIVER

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? I found that terminal registor cause significant voltage drop, so I do not use any termial registor. Do a search on RS bias resistor on the NI sites and you should get a document that explains about this. Most Active Software Boards: Is it really necessary for me to use the serial port from NI instead of using random brand serial port? 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.

Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. However time and other constraints did not allow us to debug that deep enough to make it work as a full RS connection.

Eurotherm et24xx Controller – Serial Driver for LabVIEW – 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? Now I have a strong suspicion that the Eurotherm driver you downloaded was actually developed and tested with a controller with RS interface. What did work is to replace the RS interface in the controller with a RS module and connect it to an Eurothem port on labvirw compactFieldpoint.

Message 3 of 6. 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. Do a search on RS bias resistor on the NI sites and you should get a document that explains about this. I encounter a problem with my project. On software configuration, here is the list. 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.

Or should I buy the serial protect from NI? We primarily host it for convenience.

Message 6 of 6. The REM 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. Most Active Software Boards: Message 1 of 6.

Message 4 of 6. Also, I am thinking if the issue is due to the incorrect serial port I am using. The unit I got from the client to do some testing in our office appeared to be defect, and testing in the factory installation llabview a hassle. The Eurotherm lavview can be delivered with either RS or RS interface it’s a module that can be replaced inside the controller.

This was not possible to get working although I didn’t have a chance to go very deep into debugging with this. 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. I also spent quite a bit of time for setting up Eurotherm RS Comm.

Also, the et24xx driver maybe shouldn’t be assumed to work. Message 5 of 6. Can anyone give me a hand? Is it really necessary for me to use the serial port from NI instead of using random brand serial port?

Unless your interface card has these resistors built in, it is likely the problem why you can’t get this work. 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.
