-1073807339 VISA Modbus Receive Error

Hello ,

 

I have been running this labVIEW program since the last 4 months. However, today as I run the same VI with same configurations and set up of PC, I am getting this error, see attachment.

 its a sub VI called Utility MODBUS RTU Receive Message.vi

 

its strange that the error has cropped up from no-where. The entire VI is used to read temperature from a Eurotherm 3504 Device.

 

Please help!
