But I have a question about versions... If I upgrade to Version 16, but left my program in version 15.02, would I still have this feature? Or no, because when I open the old program it opens version 15.02, and I don't get this feature? I think this feature would be handy to have. If you upgrade the computer looking at the program to version 16 and remove version 15.02 from it it will make you update the project in the controller as well. Anything looking at a real time clock will need to be checked out as the time is going to be accessed with a GSV or SSV in 16. If you leave version 15.02 on the computer it will open it in that version. I have versions from 10 to 16 on my computer to open any different files I may encounter. We recently updated four PC's and five PLC's to version 16 and other than the clock items it was real smooth, but you have to be able to take the controller off line and it does take a while to update. Then the processor will be left with the new version and no program So you have to have back up's to reload the program from. As far as finding a bit that is used, before we went to 16 i would try to cross refrence the bit before using it, slow but it works. One other thing about version 16 that is a real pain is that it defaults new tags to program tags so if you want it controller scoped you need to pay attention to change it.

I may have been wrong, looks like we used Microsoft Front Page and wrote it in HTML and it has worked since. We are not sending the data through to any type of operator station or inputs, just a web page so the owner can see how his plant is running.

We were using Java on the Eweb itself and were having slow uploads and lots of crashes for no reason. We set it up now with open office and have not had a crash since. Also we set it to auto update every 30 seconds to avoid bogging things down if no one is watching it.

We had a lot of crash problems with an web card and tracked the problem to using Java with it.

If you go to Tools, then Options, then the Xref/address tab, and check both cross refrence on line and cross refrence off line boxs then it will show up with a ladder and rung as well as the OTE, XIC,XIO, ECT... Then you would know if it is used anywhere else.
