Internet PLC Forum

I'm using Tri 6.4.1 on XP pro on this Dell precision M90 laptop.

This is more of a reporting of a percieved bug than a cry for help since I have a workaround. The workaround is never open the text editor to full screen mode and all is well.

Just to summarize, and I have tried this in both version 1.4.2_06 and 1.4.2_19 JRE, scrolling the text window of the function editor while it is in full screen mode causes "javaw.exe" resource usage to go through  the roof per task managers "Processes" monitoring tab on my machine. Also there is an accompanying condition of a painfully slow und seemingly unpredictable scrolling of the text window while this is going on. Once this mode has been entered I haven't found a way back out other than closing out then restarting my tri session.

If I were to guess I'd say it looks like it may be some issue with the directx graphics handling but of course it is only a wild a** guess. It looks to me like all graphics acceeration is disabled in this combination of conditions.

Then again I've seen errors with this machine you all couldn't seem to replicate so maybe this is another flaw of this particular laptop.

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.

Hi,

I'm new to TL and PLC's in general so please bear with me.  

Is it possible to copy/paste circuits between TL6.4 files? I think I've tried about everything I can think of to pull this off with no succes. I can't seem to copy/paste anything between files.

I can copy/paste within the same file no problem.

Thanks,
Kev.
