A really great Knowledgebase document. I am glad I was wrong in my previous conclusions. Those conclusions did seem to be reenforced by others. Also, without this article I would have chased problems with produced and consumed tags for a couple of days. One thing I should have noted is that 127.x.x.x ...

200 vs 240 was a typo because of my fat fingers. I know 127.0.0.1 is a special address. And all addresses 127 in the first octet (127.x.x.x) resolve to the local host. Most switches, routers, and hardware drivers just drop messages with 127 in the first octet. By default, Echo uses 255.0.0.0 as a mask. ...

To me it is a restriction. In my larger project with 8 controllers and all kinds of produced and consumed tags, I will have to change a lot of IP addresses to go back and forth between the emulation and real world. With my fat fingers I will probably make a lot of typos and lose time chasing them. ...

After some random testing, it seems that Echo is locked into 127 as the first number of the IP address. Result IP Mask OK 127.0.0.1 255.0.0.0 OK 127.0.0.1 255.255.255.0 OK 127.2.0.1 255.0.0.0 OK 127.2.0.1 255.255.255.0 OK 127.0.0.100 255.0.0.0 OK 127.0.0.100 255. 255.255.0 FAIL 128.0.0.1 255.0.0.0 ...

Very interesting. When I changed the subnet mask to 255.255.255.0 the red dot in RSLinx went away. -------------------------------------------

Still not joy. The new address shows up automatically in EmulateEthernet and still has a red dot. Download fails the same way. Interesting, when I put this address in the controller the subnet mask changed to 255.0.0.0

It shows up in the list but has a red dot in front of it showing it is not connected. In other words, the driver is set for Device List / Range. It shows up in the list. Echo updates the list automatically. It is still not talking. -------------------------------------------

EmulateEthernet is there. When I add new emulated controllers, it updates when new addresses. In the manual: FactoryTalk Logix Echo Getting Results Guide (Publication: 9310-GR001D-EN-P) Beginning of Chapter 2 Avoid FactoryTalk Linx port conflict Listen on Ethernet/IP encapsulation ports was ...

Another piece to the puzzle. If after reboot I start Echo before starting FTLinx I get the following error. If I start FTLinx first I do not get it.

One of the lessons I learned years ago is: "Never install FT View in the host of your development computer. Always use a virtual machine." For a while RA had coordinated product releases and things got better. They have kind of drifted off of that and it is back to the old times. They have ways to ...

RE: FT View SE Studio - Rename Bug

Found In Egroup: Advanced Software \ view thread
I am running Windows 11. I am also using Microsoft's Hyper-V. It happens in the host as well as the VMs. I suspect it something to do with the way that View interacts with Windows 11. I avoid starting a support case for three reasons. First, I find there is a much higher probability of getting a solution ...

FT View SE Studio - Rename Bug

I have found a bug that is common to Rev 14, 15, 16. If you rename a Graphic/Display it will crash on the second rename. The first one works OK. The second one works but right afterwards Studio will shut down. Really annoying. Is this known? -------------------------------------------

That works sort of. I have two drivers configured in FTLinx. One to Windows Default and one to my VM local internal network. I found that I have to check this box in both of them to get it to listen. Maybe that is what it said by "race condition". A curious observation. This is from the host. Notice ...

One thing I should have added. In a VM that cannot be found, a LInx can find other nodes that can be found. Being lost is a one-way street. -------------------------------------------

I have been trying to get several VM's in Hyper-V to talk to each other. I know that RA does not support Hyper-V. I have been reading and studying for over a week. I got the network working correctly. I set up a virtual internal network. This keeps things isolated from the web but lets the network talk ...

I doubt if my rant will make any difference but here goes. As you know Hyper-V is included with Windows 11. I have read articles that say that Windows 11 is actually built into Hyper-V and not the reverse. I am somewhat skeptical about this because Microsoft is trying very hard to sell Azure and its ...

Yes, we are far out of the Industrial Automation zone. Still, it is a very good theoretical comparison. But, when you start to run it on a hybrid core processor with a large core count and lots of RAM things change. More resources become available and the scales tilt. Not sure how much. That is how ...

Containers vs. VM's an interesting argument. I think that processor hardware is evolving so fast that container software cannot keep up and is becoming too complicate. VM's are a much simpler model and much more scalable. Still, I would not pick a winner yet. ---------------------------------------- ...
