I use LogMeIn Hamachi between PCs (www.VPN.net) because it doesn't require any firewall changes. Thanks for making me aware of this industrial router that does the same thing! Best regards, Paul Breneman www.CtrlTerm.com - communication testing tools www.CtrlPascal.com - new comedi example

> Our main control program is fixed on COM1 Can you set the PCIe card to COM1, or does COM1 already exist (from another source)?

If anyone wants to comment about using Delphi, please see my comments in this thread from several years ago first: :) http://www.control.com/thread/1294638212 The 34972A apparently has Ethernet and USB connections. Here is a blog article that shows how you can talk to it...

> My questions are regarding how to best combine Modbus data logging in a PC that is running another automation task. There is a simple Modbus example (and screen shot) near the bottom of this (free open source) page: www.CtrlTerm.com I'd be interested in taking the program further to...

www.CtrlTerm.com has Modbus RTU capability (see near the bottom of the page) and CtrlTerm has nice logging features (see Modbus screen shot). If you are willing and able to use CtrlTerm to troubleshoot I am willing to help a bit.

> I use Python nearly every day. I love it. But I would NOT use it for industrial control! ----- snipped by moderator ----- Your comments are very interesting. I've used Python a little in the past. A few months back one of the engineering magazines I get did a large amount of coverage...

You can find some stuff here that shows how easy things might be: http://ctrlterm.com/ There is a Modbus example and screenshot near the bottom of the page. There is info about USB to RS-485 adapters. These things might be useful (as a troubleshooting tool) even if you end up using a...

> A few weeks ago I released new open source freeware for serial and socket (TCP/IP) communication: > http://www.ctrlterm.com/ > I'd like to add Modbus and other examples so let me know if you find such interfaces on sensors for your application. I just added a simple Modbus program and a...

> Here is another option, I have not used them myself but they look nice: > http://www.embeddedarm.com/products/touch-panel-computers.php Yes & thanks for mentioning these Bill! I've had a TS-TPC-7390 for about 7 years but at 200 MHz. it is a little slow...

> Out of curiosity, why do you avoid using Android? I've done a little Android programming with www.Processing.org and I mentioned that on this page: http://www.turbocontrol.com/mobileard.htm I've done a lot of Windows, WinCE, and Linux programming using these free open source tools that...

Sorry that in my previous reply I didn't mention anything related closely to the original message. That is because I want to use Linux (or maybe ReactOS) and avoid Android. Here is the least expensive industrial device I hope to use: http://www.emacinc.com/panel_pc/pdx089.htm

I have a list of Samsung and Asus Android tablets that should start delivery in the next few months. With prices about $150 (US) for 7-8" models, and x86 CPUs (Linux software for x86 is probably more mature than for ARM) these look like nice tablets to reload with Linux (Debian or Ubuntu) and...

I am working recently with something similar: http://www.slideminder.com/ What is the distance your wire moves? The movement is very little with the stuff I'm working with. A few weeks ago I released new open source freeware for serial and socket (TCP/IP) communication...

I just added TCP/IP capability and put it on a new web page: http://www.ctrlterm.com/

Here are some simple open-source zips I just updated a couple of days ago: http://www.turbocontrol.com/easyfpgui.htm They work in i386-linux and arm-linux as well as windows. The DbgTerm program is similar to HyperTerminal but is easy to modify since it has very little code. I hope to...
