Could not perform operation because of I/O error. Error -1073807298 Using Newport SMC100 controller and TRA25PP actuator

[MagnusBL]

I keep getting the -1073807298  error when trying to control a linear actuator from Newport through a Newport SMC controller using some vi's supplied by Newport. I have traced the error message down to a VISA read function which generates the error.

However when I switch on execution highlighting there is suddenly no error. Then when I open the vi where the Visa read is located and switch on executon highlighting here, I get the error again! Peculiar, i must say.

I have tried both USB-RS232 and direct RS232 connections without any luck

I have also tried to add a VISA set IO buffer size and changed the size from 4096-200000 with no change.

Any other ideas to solve the problem? I could perhaps just ignore the error but that doesn't seem quite right.

I am using a vi example that can be found at ftp://download.newport.com/MotionControl/Current/MotionControllers/SMC100/Software/LabVIEW_Sample/

Do a search in the forum with the error code. You will get a couple of threads discussing the same problem. Post back if you still face issue.

I have searched through the forum and tried some possible solutions which could fit my problem (e.g. not use USB-serial converter and changing the IO buffer for the VISA read/write). Neither have had any effect

I had identical problem with "VISA: (Hex 0xBFFF003E) Could not perform operation because of I/O error". The solution for this issue in my case was to simply remove "VISA Shared Components" from the main list in "Add or Remove Programs".

LabVIEW 7.1.1

NI VISA 4.5

I had some of these issues, and overcame them as shown here.

Hope this helps,
