Hi, I have CX Programmer version 8.01 and have become (didn’t happen with an earlier version) frustrated when I go "online" (typically serial comms via USB to serial and at 19200)and monitor a program - the display freezes / is slow to update when you click between sections of the program or scroll up and down a section using the mouse scroll wheel or slide bar on screen. On-line edits are a nightmare and the program often crashes. I noted that the Comms indicator LED on my USB adaptor seems to be in sync with this freeze as the indicator is off while the screen freezes and then starts flashing when the display un-freezes. I don’t think it is the USB-serial adaptor because it works fine with my Rockwell & Schneider software and wasn’t a problem in an earlier version. What’s going on Omron!

Ps Computer spec is good Win XP SP3, 2GB RAM, 1.7Ghz Centrino processor and 250GB harddrive.

Have you tried updating to the latest version?

This seems to be a similar issue:

I remember the same thing when I first installed CX-One Version 3.??
It appeared to be a CX Server issue.
PdL's solution (online update) quickly cured the problem.

You can also set CX-P to connect automatically at 115k. 19.2 is very slow.

Hi, all fixed - Auto Update sorted things out.

was running CX Programmer version 8.01 and CX Server ?.? (July 2008)
now running CX Programmer version 8.20 and CX Server 4.3 (2009)

Have also set baud rate higher (19200 max) but didn’t notice to much difference will probably revert to default (9600)to avoid future issues getting online.

Thanks for your feedback.

Thanks for getting back
Regarding the connection speed, like BobB said you can always check auto baud rate.
