Best Program for Transferring Melsec PLC to Shihlin PLC: Medoc vs. GX Developer

Question:

Hello everyone, I am currently working on a project involving an industrial site entry gate system. The system is currently operated by an outdated Melsec PLC, and I have a spare Shihlin PLC that I plan to transfer the program to. I am seeking advice on which program to use for reading and copying the program - whether it be Mitsubishi's Medoc or GX Developer for Shihlin. This project is relatively small and straightforward, just one of the tasks on our work list. We are looking for a cost-effective solution and have a programming cable available. Any guidance on a simple and basic program for copying the program would be greatly appreciated. Thank you in advance for your assistance.

The compatibility of uploading GXDeveloper depends on the Mitsubishi PLC version you have. If you're using an older F series or FX PLC, you may need a special F2-20GF1 interface, which can be found on online platforms like eBay. However, these interfaces have been out of production for many years. The current GXDeveloper versions do not support the F series, so you may need to use Medoc, a DOS-based software that is no longer commercially available but can still be found online. The FX0-3 series is also becoming outdated, with the newer FX5 range replacing it. The Shihlin PLC is similar to the FX series, but compatibility with Mitsubishi software may vary. Despite some differences in functions, a simple program should still be relatively easy to configure.

Sure thing, I've dealt with a similar task in the past. I've found GX Developer to be more user-friendly and better supported for this type of work, especially if you're not very familiar with Mitsubishi's interface. It should be more than capable of handling the programming needs for your site entry system. However, make sure to double-check program compatibility between the Melsec and Shihlin PLCs, as there may be slight differences that need to be edited during the transfer process. Good luck with your project!

Hey there! For a project like yours, I'd recommend using Mitsubishi's Medoc if you're working directly with the Melsec PLC, as it can effectively read and transfer the program to the Shihlin PLC. However, keep in mind that you'd also need to adapt the logic and instructions since the Shihlin PLC may have different command structures. If you're looking for a simple and cost-effective approach, try to familiarize yourself with the Shihlin programming environment early on—it can save you time when it comes to modifications. Good luck with your project!

Hey there! If you're looking for a cost-effective way to transfer the program, I’d recommend using the Mitsubishi Medoc software to read the Melsec PLC program first. It is more straightforward for basic tasks, and since it's your starting point, it’ll give you a better understanding of the logic before transferring it to the Shihlin PLC with their own software. Once you’ve got the program extracted, you can easily rewrite or adapt it in the Shihlin environment using their tools. Good luck with your project!
