More that likely you are SOL without a copy of the code. Contact the folks who originally commissioned the system and failing that, contact the manufacturer. Passwords are designed to give the...

That looks like a SLC fixed hardware style. Yes, RSLogix 500 supports it. The RJ45 socket is DH485 NOT Ethernet. It has 24vdc on one pin, so use the correct cable with it. If you don't have one,...

Yes, my project using Modbus to poll Phoenix Contact TWE with I/O gives the same warnings. It might be a good example of how to poll multiple nodes for you to follow.

I think they mention that the CR1000 series doesn't support data logging, but then they let you create a log file and trend it on the screen. It will only trend as many data points as it can hold in...

The A/B DF1 protocol allows for a masked write where the driver (if using that feature) doesn't have to perform the read in advance just to diddle one bit within a word. This isn't really relevant...

If you have the PLC/SLC mapping set up in the new PLC exactly right, you should not have to change anything at all in the Panelview. Make sure that the data types you have mapped are correct.
