Posted 30 Jun 2020 Hi Guys I am trying to change a profibus module on a Q02CPU from a QJ71PB92D to a QJ71PB92V, but when I try to download I keep getting the error Flash ROM writing could not execute rightly. Now I can download and upload code thus I think the Cable and PLC power OFF is a null. How would I do this? I am using GX Works 2, as I do not have GX Configurator AD. Kind Regards Morne Share this post Link to post Share on other sites
Posted 1 Jul 2020 You need to have GX config DP installed. Share this post Link to post Share on other sites
Posted 1 Jul 2020 Hi Gambit I do have GX Config DP installed, but when I try to download to module I get the attached error. This has to do with there previously being modules on the PLC rack, that are not there anymore. Any idea how to get past this? Share this post Link to post Share on other sites
Posted 1 Jul 2020 Hmm maybe the io adress isn't the same anymore. Check the system Diagnostics and the IO set for the module in GX Works 2 Share this post Link to post Share on other sites
Posted 1 Jul 2020 The IO set looks fine, but the SP para Error remains in the diagnostics no matter what I do. It blocks me if I want to download anything hardware related. Share this post Link to post Share on other sites
