Has anyone had trouble with slow updates of tag data in LabVIEW DSC v 6.1? Or better yet, have a resolution to the problem! We have a control system that consists of an Allen-Bradley PLC SLC5/05 connected via Ethernet to our HMI PC. Occaisionally (once a week or so), the control system bogs down to the point where it may take 60-90 seconds for a control actuation on the PC to get a response from the HW in the field. There are a few hundred tags set to update 5 times per second. Most of the time, the system is very responsive. When we get into this state, rebooting the PC resolves the problem. I cannot recall the version of RS Linx at this time.
Turn off Virus scanning on your Citadel data directory. It's a known issue, though it may not be what's causing your particular problem.
