Good morning @EPHRAIM,

As you can see in my article and video (link below) this typically does not happen:

So if you need help finding what is causing the issue, we'll need more information, like:

If you select yes, does the same thing happen?

If you say no, can you view the program offline?

Are you directly connected via Ethernet, or going through a switch which also connects to other devices?

What mode is the PLC in?

What versions of Windows, RSLinx, RSLogix are you using?

thank you for the reply sir,
If you select yes, does the same thing happen? once i press yes it goes gain asking me to create a new file, then save, after do you want to go online if yes the same information appears
If you say no, can you view the program offline? i cant without saving
Are you directly connected via Ethernet, or going through a switch which also connects to other devices? directly connected to Ethernet
What mode is the PLC in? RUN mode
What versions of Windows, RSLinx, RSLogix are you using? window 7 professional 32 bit, RSLinx 2.75, RSLogix 8.10.00 CPR 9

Good morning @EPHRAIM,

1) Which RSLogix do you have - it will show at the top of the program in the title bar, something like RSLogix 500, Micro, Micro Starter, Micro Starter Lite
2) Try remote run mode
3) Insure your PC is on the same subnet as your Ethernet PLC
4) Try a different network cable

Hope this helps,
