  1. That's a tough situation. In the future, when you have an integrator do work for you, make sure in the contract or quote that you get the source code and password. I am in the camp that when I do work for someone, I always felt it was YOUR property when I was done, not mine. But in some cases, if it's an OEM machine, then I guess I can understand that but it does a pickle for some good folks like yourself. Password cracking is not a good subject here, because software is legal property is why we have to be careful. We don't want anyone getting in trouble.

  2. I think most people who know me on MrPLC, know that I am a crazy Christmas light NUT as well... Check out my latest project...Christmas Light Controllers Meet Robot Programming....LOL. http://www.botmag.com/yamaha-industrial-robot-makes-disco-debut-on-custom-lighted-dance-floor/ What do you guys think?

  3. So I just had this happen in version 21.01...and what I found out was this.. I had version 21.01 installed on my laptop and my co-worker upgraded his version 21 to 21.03. After he downloaded the PLC program and offline program, I could not open, go online or anything with the PLC nor the offline copy until I upgraded my software to the same as his. I had to ask him what version he had and put two and two together to figure that one out. Do you have an "evil" co-worker too with a newer version of 20?

  4. It was a model made for a trade show. The company sells LED signs, (I actually wrote AOIs for them as well so you can communicate messages to the signs over EIP for Allen Bradley...way cheaper than an InView). But they are selling signs to parking garages to tell you how many spaces are open on each level. This is a model version.

  5. File Name: Click PLC with Analog Sensors and RS-485 File Submitter: Chris Elston File Submitted: 09 Nov 2014 File Category: PLC Sample Code Here is a sample video with a Click PLC. Mainly purchased this because the Click PLC offered RS-485 for some LED signs that I needed to communicate with. Really nice, easy project. My first Click PLC. Free software and super easy to use.

  6. Did a project recently with a Click PLC using Analog sensors and RS-485 to communicate with LED signs. Pretty nice value PLC for smaller projects. http://woobox.com/rshjfw/vote/for/5161807 Vote for me if you like my project with the Click PLC. Attached is the PLC source code below. click_plc_sample.zip

  7. First thing is buy a Micrologix PLC on eBay. Get your hands on one. Allen Bradley now has FREE software for Micrologix PLCs, so you can atleast get your hands on one and get free software. You'll need to pick up a programming cable (1761-CBL-PM02), which you can for pretty cheap too. Then like me, find stuff to automate, like one year I got bored, and did a PLC Halloween garage. "plchalloween.com" not the greated website, but has stuff I built and programmed. Download the free software or on Allen Bradley's website: http://forums.mrplc.com/index.php?app=downloads&showfile=868 http://www.mrplc.com/kb/Free-RSLogix-Micro-Starter-Lite-Download_86.html Cable Purchase: http://store.plccables.com/Allen-Bradley--1761-CBL-PM02_p_12.html I also have used a PLC for: Base board heater control Broken water softener Halloween Christmas Automatic Mail notifier and the list goes on and on and on... The point of the matter is, getting one in your hands and tinkering with is so you understand going online, editing, memory bits, input / output, then kinda move up from there to actual projects. I also know around here, I helped a couple of greenhouse people with a PLC, and automatically turning on watering valves.
