How to program SMC100

[Albert.Geven]

check tools/options and uncheck use locaied decimal point.

Our USA friends don't understand that it is a wrong default in LabVIEW to check this,,,,,

Hi, I am trying to programme SMC100 using LabVIEW. I have few codes which used to work but suddenly started showing error at initialization VI 'port initialize'. The error code is -1073807343. The inputs are com port, axis number and timeout. The controller works fine when operated through the GUI. Can someone suggest a possible way of fixing this error?. Thanks!

Hi

a long time ago I had the same error. The library was the problem.

I'll try to find my rewrite with VISA.

takes some time to find it, have to be at home for this.

Hi

I only found a library from 2005 from Newport.

The problem inside that library is that they are using "bytes at port" to determine the end of the communication but you can better update that with waiting in VISA for the termination character. Timing in windows and trying to ask a lot of small data parts only makes everything slower.

I don't know if you have the same lib but it is called 

SMC100-Controller-Drivers 

sorry for not finding my specialised version.

Thanks Albert. Geven,

Yes, I am using the library  SMC100-controller-Drivers. Sorry, but I am new to programming VISA  resources. The error is at the initialization VI. I have attached a screenshot of the VI for reference. After I input the COM port (checked in device manager and SMC100 GUI) and timeout (300ms) , the error is happening in the function 'Old VISA Open'. Could you please see if there is any possible mistakes I am doing? 

[Albert.Geven]

I attached a version LabVIEW 2020

If this still does not work increase the timeout

You now should select the correct com port in the VISA resource.

If you don't have one check windows device manager and MAX from NI.

I only removed old stuff that is for over 10 years nonsens

Thanks a lot Albert.Geven!! The issue got resolved.
