Important Notes from Moderator
We recently received several reports that program transfer is often aborted half-way or require multiple attempts to transfer program to the PLC. This happens whether the program transfer is via TLServer or the Ethernet.
It appears these problems only surface after user has upgraded to JRE 1.6.0 (especially 1.6.0_24). So far in all cases the problem was resolved after the users uninstalled JRE 1.6.0 and re-install JRE 1.4.2. Therefore we strongly recommend that you keep your JRE 1.4.2 even if you must upgrade to JRE 1.6.0.
The following posts discussed the problem and the solutions.

I am often experiencing apparent lockups or stalls while downloading code to the PLC through the ethernet port via Tri 6.4 ctrl+T.
Quite often it will stall part way through the download sequence and the only option seems to be an abort followed by a retry. No amount of waiting seems to allow these stalled conditions to clear themselves and so the abort option is the only thing I've found to pull the system out of this "stalled" state. Quite often I will get several instances of this happening before I can finally download to the entire set of code to completion.
I am wondering what I am doing wrong or what I can try to improve reliability of downloading the software to the PLC. It is taking up quite a bit of my time just trying to get my various code versions to "stick" and I'd rather be writing code.
