That’s correct, and the ability to turn it on and off is only available when logged on as Administrator.
I was hoping one of the Wyse experts might have some input. Also, once delivered to the field, how are people setting up the thin clients to automatically start up and connect to the server, displaying the Ignition program?
We have a lot of Wonderware around here and in the past they provided a program called Startit to sequence the startup of programs.
Just putting links in the startup folder doesn’t guarantee their order of execution.
Finally, I started using a batch file that would ping 127.0.0.1 once a second for x numbers of times. There was not a sleep command that could be used to generate the delay.
This way you could be sure programs started and had sufficient time to stabilze before starting the next one.
Question, if FBWF is enabled, do you lose any log files or data files on reboot? Place them in an unprotected partition?
Back to your original question, I’m working on my first Ignition project and have set up an Ubuntu server with some HP t5565 thin clients (~$235 ea.). They have a 1Gb SSD and 1Gb RAM and run an HP OS that is actually Debian Linux and comes with just about everything needed pre-installed (including the Java jre) and an ELO touch driver.
While I haven’t put this into production yet, from what I can see so far, they appear to work quite well for this application.
Has anyone come across a thin client-like setup that includes a 6-8 inch touchscreen display? We have a project that will require a small form factor client, but that will likely need to be either panel mounted or in-vehicle mounted. Thanks!
I am looking for a simple to implement, panel pc to replace some PLC touchscreens. Size is about 10". I read though all the posts in this thread and wonder if the recomendations are the same given how technology becomes outdated so fast. What are you guys currently using out there. I must avoid linux based solutions since I already lost that battle here. We are currently paying $1,400 for vendor specific panels so I think budget is a non issue.
Thanks
I still install the same hardware as before. The only thing that I’d recommend differently is that I had to go away from the SSDs as they were just not holding up-- but it was still worth a shot to use!
Also, having separate units (monitor and PC) lets you replace one or the other cheaper than replacing an entire set (like a PV+ or PPC)
There are certain workloads that SSDs aren’t perfect for.
Using them as scratch disks for lots and lots of non-random writes is one of those.
Consumer flash’s number of write cycles per cell determines this.
We use SSDs in all of our SCADAs now and have had great luck with them. Some tweaks are required, disable defrag, disable indexing, etc.
We had heat issues with them. They weren’t really rated for industrial environments, and, well, eventually it showed. They worked great for a few months, but overall, it wasn’t one of our more stunning successes.
Part of the heat issue we came across, was that the 19in screens we use put out a surprising amount of heat. Enough so that the fans on the cabinets couldn’t keep up.
I am going to be ordering this unit, thinking I am going to put linux mint on it, and see about running some screens. Not running the designer though. The designer is very “resource hungry”
It is fiarly economical but not “industrial” but I can put this little guy just about anywhere…
I am going to hook it to my 46 inch lcd and see just how hard I can push it.
I can say that I know of at least one integrator who is using those boxes mounted to the back of a touch screen (they built their own mounting bracket). I wouldn’t recommend it for harsh environments, but for where they’re using them, I think they’ve been pretty happy with them.
I’m putting a touch screen OI at a remote site that has a vpn connection to the server that during normal operation will run the client App. But will also have a panel edition version of the app installed so local control could still be maintained in the event of a communications failure. The question is would a PC like the ASUS EeeBox that tailfire mentioned be suitable/capable of running the panel edition app or should I be looking for more horsepower. The panel edition app will be monitoring/controlling < 100 data points in the PLC.
