Posted 27 Sep 2022 I have a client that has an old extruder system that is controlled by a GE Fanuc 90-30 PLC. I have been trying to get the running program out of the PLC so we can update with out having to write a new program. It turns out the program was loaded using Logicmaster software and can only be read by Logicmaster software. I cannot find Logicmaster software for free (trial?) or to purchase anywhere. Any ideas? I would really appreciate any guidance. Thank you. Share this post Link to post Share on other sites

I haven't been using it lately, but I've connected to many 90-30 model with Proficy to pull old programs out. They'll never show "Logix Equals" with a different programming tool, but that can be correctly by re-downloading. Do note: the 90-30 does not carry the comments in the processor. The original logicmaster files, if you have them, can be imported into Proficy. Share this post Link to post Share on other sites
Posted 28 Sep 2022 I am able to connect with Proficy but the PLC crashes every time I try to read the program. Everything else seems to work fine. A specialist I worked with at Cimtec told me if the program was loaded with LM it can only be read with LM. On the internet I found other people who have had this same problem and using LM was their solution. I checked and our program was loaded with Logicmaster so that is what I am trying. I am open to any other ideas. Share this post Link to post Share on other sites
