I am attempting to establish a connection to an Rx3I via Ethernet for the first time, aiming to review the ladder logic and monitor the inputs and outputs while the machine operates. Unfortunately, I do not possess the original program file; however, the manufacturer has confirmed that the program does not require a password. My background is primarily in Allen-Bradley (AB) PLCs and various CODESYS PLCs, making this my initial experience with GE PLCs. I usually rely heavily on online tutorials, but I can't find any guidance on uploading existing programs to my PC without having the original file (most resources only cover connecting to the device and downloading). I’m quite concerned about accidentally overwriting the CPU with a blank project. So far, my understanding is that I should create a blank project, select the appropriate CPU, and input the IP address in the Hardware Inspector. What should I do next? I am currently onsite at the customer's location and would greatly appreciate any advice.
After creating a blank project with the appropriate CPU and IP address, you should establish a connection with the PLC. If your Proficy project is misaligned with the PLC’s hardware and logic configuration, you’ll notice a red "X" icon over the target in the navigator tree. At this stage, you can proceed to upload the project currently running on the PLC into your Proficy workspace. Once the upload is complete, ensure you save the project for future reference. For those looking for resources, you can find downloadable PME manuals on GE’s official website: [GE Digital Support](https://digitalsupport.ge.com/commu...850-800-and-750-Getting-Started-manuals-en-US).
Sapper307 explains: After creating a blank project with the appropriate CPU settings and the correct IP address, you should be able to establish a connection to the PLC (Programmable Logic Controller). When you examine your Proficy project, a red "X" will appear over the target in the navigator tree, signaling that the project does not align with the hardware and logic configurations of the PLC. At this stage, you can upload the project currently running on the PLC into your Proficy environment. After successfully uploading the project, make sure to save it for future reference. For further assistance, you can access GE’s website to download PME (Proficy Machine Edition) manuals at the following link: https://digitalsupport.ge.com/commu...850-800-and-750-Getting-Started-manuals-en-US. In particular, consult page 50 of the GFK-1918S manual. Although the buttons and toolbars may appear slightly different based on the version of PME you are using, the overall functionality remains consistent.
Thank you! I successfully connected and uploaded the software to my PC. As I enjoy a cup of coffee this morning, I'm diving into the program and its files. However, I'm finding it a bit challenging to grasp everything. It’s likely due to the learning curve I’m experiencing, especially after spending so much time with Logix 500.
In my opinion, without sparking any heated debates, if I were to evaluate both logic programming formats simultaneously, I would find GE (General Electric) to be more straightforward and user-friendly. There are several key distinctions between the two systems: First, GE uses decimal numbering instead of octal. Additionally, it does not typically rely on a rack and slot configuration for I/O addressing or sequencing. With GE, users can easily check the hardware configuration to determine I/O locations or utilize the "Search" feature to find them quickly. Moreover, GE allows you to "force" any memory I/O or real I/O bit, meaning you can manipulate any contact in a rung or any coil. When making online edits, it’s simple to accept changes—just right-click on the left rail and select "Accept Edit," without the need to perform a "Test Edit" beforehand. There are certainly many other advantages to consider; however, in Machine Edition, features like the "Companion" window and the "Inspector" window effectively provide explanations for any element you select. This combination of user-friendly tools makes GE an accessible choice for users at all levels.
I'm currently utilizing the 4-day trial version of software on a Windows 7 virtual machine. My intention was to print out some of the ladder diagrams, but unfortunately, the print feature is disabled, likely due to the trial mode restrictions. Having this ability would be incredibly helpful as I’m aiming to deepen my understanding of the machine’s logic, and I prefer to take notes directly on the printed pages. I also suspect that all the comments within the ladder are included in the original file, but they aren't accessible here, making it a bit challenging to comprehend the addresses completely. I'm gradually becoming more familiar with the software, and I found it much more intuitive during my second session. I’m genuinely excited about the prospect of having this application on my laptop. Additionally, I have another client whose system employs one of Automation Direct's Direct Logic PLCs, which will require a copy of the software to diagnose why one of the outputs isn't maintaining its active state throughout the entire cycle. This aligns perfectly with my interests! I’m eager to take on more PLC-related projects, and having access to this software will be a significant advantage.
It sounds like you're in a bit of a tricky situation, but you're on the right track! Since you don't have the original program file, your best bet is to establish a connection and then upload the current program directly from the Rx3i to your PC. In the software, after creating your blank project and entering the IP address, look for an "Upload" option—this should allow you to pull the existing logic from the PLC into your project without overwriting it. Just make sure you have backup copies of everything if possible before you proceed. Also, don’t hesitate to check the help documentation for the respective software you're using; it might have specific guidelines for this process. Good luck!
It sounds like you're on the right track with creating a blank project and entering the correct IP address. Just to be safe, before you start any uploads or changes, I'd recommend double-checking if you can access the existing program in 'read' mode. This might allow you to view the ladder logic without rewriting it by accident. Also, make sure to back up any existing configurations if possible; you can usually save them directly from the PLC. If you're in the Ge fan community, trying forums or user groups focused on GE PLCs could also yield valuable tips from people who've been in your situation. Good luck!
