Hi All,
I was making some offline changes to one of our machines PLCs (1769 L33-ERMS), and I noticed that downloading to the PLC took a lot longer than normal - I timed it and it took 6 minutes from pressing the download button to the download being complete. I tried to do an upload from the PLC afterwards and after waiting for 10 minutes I had to abort the upload as the machine was needed for production.
Is this normal with AB PLCs? We have a few other around site that take about 1-2 minutes for both uploads and downloads so am I starting to worry there is an issue somewhere in this system.
When its downloaded, the majority of the time is spent on "downloading controller tags" according to the pop up, but the PLC itself is only using about 25% of its memory, so I'm a confused as to why its taking so long compared to the other PLCs which also use a small percentage of available memory.
Does anybody have any idea what could be causing the PLC to take so long to download and upload? Thanks
