<div class="markdown_content"><p>I am going to take a chance and post my email address on this thread. After all the whole purpose of<br/> this forum is to trade ideas and help. Then I can get an idea of which version (3.5.5.4 or 3.5.5.1) I<br/> should be working with. Thanks so much for the info.</p> <p>NOTE: Anyone reading this thread who has even a shred of info concerning the HFX PLCs including<br/> installation, and use of the device, please feel free to include it. You can never tell when even the<br/> smallest detail can open doors that have been locked for a long time. Thanks in advance....</p> <p>DPguy</p></div>

<div class="markdown_content"><p>Maybe if you add information under your profile for Skype or Google I can add you and talk that way. Not sure what all is visible to other users. Since I can't see your email through that.</p></div>

<div class="markdown_content"><p>Thanks for the information. Sometimes knowing the "BIG" picture helps me to know what is going on<br/> in the industry and more of this stuff is starting to make more sense. I am anxious to get this project<br/> a little further down the road. If this site would allow it I am willing to post my number so we can<br/> talk and maybe then we can find a way to get the 3.5.5.1 version to me. I still have 1.4 of the<br/> firmware just haven't copied it to the device yet. If you can think of any way I can get my hands on<br/> that version I will be willing to try. I have an email address. It may be possible for you to attach the<br/> file to an email and send it to me. If you think that will work, let me know.</p> <p>Thanks for all this help. I have learned more in the past few days than I have since I started the<br/> project in Dec 2015. Thanks for "Comingback 4me".</p> <p>Sincerely....DPguy</p></div>

<div class="markdown_content"><p>Latest version of firmware and latest version of the IDE won't help as they haven't updated the runtime on the firmware. I have version 3.5.5.1 just not sure how to get it to you.<br/> To somewhat answer your questions 3S software is free for the most part. The requirements are you have to use it on a device that the manufacture pays for the license to have it on OR you have buy a license to run it more than 2 hours on devices like a raspberry PI or a personal computer. In this case Eaton pays for the license for each of their devices. Where extra cost can come in is if the manufacture creates their own libraries or re-skins the IDE. You don't have to use the manufactures libraries in most cases but if, like in this case, they run off a certain runtime and you can't get the same version what else can you do?<br/> There are a few companies out there that offer CoDeSys version:<br/> 1: Eaton (Charges for license to use their re-skinned IDE and libraries)<br/> 2: Maximatecc (No license is needed)<br/> 3: IFM (No license is needed)<br/> 4: Wachendorff (Charges for license and support but not required)</p> <p>I bet there are more out there for the mobile market and it would be awesome if they posted to let us know. 3S name is known a lot more in the industrial market from what I am aware of.</p></div>

<div class="markdown_content"><p>Thanks so much for the reply. This is very helpful. Since you also had the same problem at least I<br/> know that it wasn't just me. I may have to get Pro-FX to make this thing work but I hope that will<br/> be the last resort. I just wonder what would happen if I used the latest version of the firmware and<br/> the latest version of the IDE. If that does not work, I could try to get the older version. I am a few<br/> miles north of Memphis, TN. If I try to use the older or newer version, of the software, is it just a case of uninstalling the current version and installing the new one, or is there something special that must be done? I won't mention the supplier I got the equipment from but I can tell you that they are the largest distributor of Eaton products in the world. There are a couple of thing that are not apparent to me from the 3S site:<br/> 1: Is their software truly "no charge" because they talk about a "trial version". How can it be<br/> "no charge" and a "trial version" at the same time?<br/> 2: Is 3S used a lot in the industry or do most application developers use the version marketed by the<br/> company that makes the PLC devices?</p> <p>If you can think of a way to get the older version to me I will try what ever it takes.</p> <p>Thanks so much for sticking with me on this. This seems to characteristic of people in the computer<br/> business. They stick together.</p> <p>DPguy</p></div>

<div class="markdown_content"><p>Firmware version 1.1.0.11 (1.2) and 1.1.2.13 (1.4) both use the same CoDeSys run-time of 3.5.5.4. I guess I skipped using version 1.3. I would use version 1.4 as the memory on the device was optimized. I tried installing 3.5.9.4 and loading an application and ran into the same issue you did. It has something to do with the difference in how it builds the program. If I open a 3.5.5.4 project in 3.5.9.4 I can login to the display as long as I haven't made any changes. As soon as I make a change I can no longer login. So you have two options in my mind. <br/> 1: Find someone with an older installer version. If this site had a way to PM I might be able to help you out with this.<br/> 2: Buy the license to use Pro-FX. If you buy the license though I would buy it from a distributor that knows what the product line is and how to use it so that you can get support if needed. This depends on where about in the world you are.</p> <p>Best of luck.</p></div>
