Hey everyone, i got the system online. studio 5000 has an option to upload program at the startup screen, luckily it worked for me, also the version 24 stores the rung comments so it was easy to modify the program.
thanks everyone.
That's good to hear.
Just to point out that for the 1769-L24ER controller, or other 5370 CompactLogix controllers,
it would not be a given that project documentation would always be stored in the controller. With respect to this feature, they, unfortunately, still have a "toe" dipped in the "undocumented ointment"...
As these controllers were introduced when RSLogix 5000 v20 was current, they may be flashed to firmware revision 20 minimum, or, since Studio 5000 v21, from firmware revision 21 up to the latest. Only if they are flashed to the latter will they support the storage of project documentation in the controller. A firmware revision 20 controller cannot save the documentation in the controller as RSLogix 5000 v20 software does not support this feature.
For v21 or later, this feature, "Download Project Documentation and Extended Properties" is enabled by default. So in general, or if users are not aware of it, the default is to automatically save this valuable information when downloading. If you disable the feature just before download, then of course a traditional download is performed and the project documentation would not be stored in the controller.
I would also strongly advise you to not rely solely on the fact that these controllers may now also store the project documentation. It is good and standard practice to save a project copy local to the site, remotely with yourself, and optionally a copy on the controller's SD card. That is, a full copy of the project ACD file manually transferred to the SD card, as opposed to the compiled copy of the project ACD we download to the controller's memory. You could also store other project documentation on the SD card, if you wish.
Another advantage of saving a copy of your project files on the SD card is that even if the controller clears its memory, the SD card will usually retain its contents. But still, in case of a catastrophy, such as fire, flooding, etc., it is prudent to retain copies in a safe place.
