You do not need (or want) Produced/Consumed tags. The setup should be essentially the same as what you already have, but point the connections of your HMI graphics or whatever to the CompactLogix...

It's been a long time since I used anything other than an actual AB 1747-CP3 cable, but I seem to recall that a standard null modem cable as you describe would work.

You do not use a name 'instead of' an IP address. Any device on a network will have an IP address. A hostname essentially serves as a translation of an IP address into a more human-readable format,...

If your device is on the network, it's going to have an IP address. Your hostname doesn't provide any benefit if other devices can't resolve it to an IP address.

None of this addresses the OP's issue in the slightest. The program (logic) is not changing, the desire is to remove the ability of the HMI to change a specific value that it currently accesses,...

afaik there's not a 'lock' for single addresses as you describe. I don't think you're getting away without changing either the HMI or PLC program.

If you want to avoid changing existing logic,...

The setup or connections of your serial ports should have nothing to do with the memory card. A proprietary card is not needed, but it is picky about formatting.

While this is highly desirable for obvious reasons, it is not, strictly speaking, 'necessary' and as such should not be the cause of the issue here. The Rockwell technote (ID: QA56408 | Access...

If you were actually using an original panelview, then you'd be on the right track with the mapping.

Sounds like you are using a Close Display button on a Replace type display. Instead use either Goto or Return To buttons. Only use Close Display buttons with On Top displays.

You will be able to upload/download everything, but not view/change the routines you do not have a license for.

Wireless Power Transmission already exists (although perhaps not at the scale we're considering), and would at least give the appearance of producing power from 'thin air'.

I'm not familiar with the SMC Flex line, but sounds like it's wired from pushbuttons. I'd assume the 'display' is on the drive unit itself.
