Serial (RS422)Labview VI becomes slower at some time, need help !!

[Saqib51]

Hello, 

I am receiving data on RS422 with BR 926100. My application runs fine, but sometimes it becomes very slow (happens ones in a month) and I am losing the data. I am using another application in C++ to receive the data at the same time, but no data missing occurs. This issue makes my VI in LabVIEW unreliable at that time. plz help.

Hello, I am receiving data on RS422 serial port with a baud rate of 926100. The fresh packet is received after 15ms. The length of the packet is 52bytes with header ATE and in the end, CRC16 is computed to validate the packet. The issue is that I am encountering data loss or missing the packets in a large number. I am also enclosing snaps shots of my code. I) shows ports configuration and 2) is packet receiving logic which I am using.

Regards

I assume this is related (duplicate?) to this post.
