Error 64 Serial Port Framing Error

[jspinozzi]

I am trying to communicate with a CompactRIO unit using LabVIEW Real Time being controlled from LabVIEW running on a Windows PC.

I get the following intermittent error in the communication between the LabVIEW for Windows and LabVIEW Real-Time communications.

Error 64 occurred at TCP Read in RTCW TCP Send Receive.vi->NPL_Motor Velocity Control- Function Generator as Blender no PID(RT).vi

Possible reason(s):

LabVIEW:  Serial port framing error.
---
LabVIEW:  The network connection is not yet established.

Any pointers would be greatly appreciated.

Hi Joe:

Does your Time Critical Loop sleep for a sufficient amount of time? I would try to see if the problem goes away if you increase your wait inside the TCL.

This discussion forum thread might help shed some light on the issue:
