PLC-PT Integrated Simulator and online Simulator

[Kevin Do]

Hi Everyone, I've been using CX-Programmer for a couple of months now and noticed one day that the PLC-PT Integrated Simulation and online sumulator was faded out, meaning I couldn't start them up. The shortcut icons on the toolbar for them was also faded out. It seemed like these two options were disabled somehow. I called Omron up and they were stomped as to why it had happened and they have never heard of it fading out before. Has anyone ever had this happen before? I got the simulators to show up again when I put the CX-One cd in and did a repair on the existing installation.

PLC-PT integrated simulation and PLC simulator is only available for for specific processors in CX-Programmer: If you do have one of these processors selected and still no available options, there are multiple reports of this problem here. In this topic you find a fix that worked for me: CX-Simulator disabled from within CX-Programmer ? Re-installing CX-One also fixes these registry keys. Do you use any disk cleaning software that also cleans registry keys?

Hi PdL, Thanks for the feedback. So it is a registry key problem? I have tried re-installing CX-One and it worked for me when this problem first occurred, on the second occurance I just did a program repair and it seemed to fix it as well. Seems like this is a re-occurring thing, I have a feeling it might be my Norton Antivirus that's deleting the registry keys.

Hi Kevin, Yes it is a registry key problem. There is a registry key that defines the patch CX-Simulator is installed. For some reason registry key cleaners mark this key as invalid and delete it.... Probably CX-Programmer determines if CX-Simulator is installed or not by checking for this key when launching the application. Key present means CX-Simulator is installed, key not present means it is not installed. The cleaner I use has an option to manually add keys to skip the cleaning process. Another workaround would be to create a *.reg file (notepad file saved as *.reg) with one of the path keys as described in this topic (sorry the link above missed the mrplc url) You would have to check what folder CX-Simulator is installed and apply the key accordingly every time CX-Simulator becomes unavailable. CX-Simulator disabled from within CX-Programmer ?, What am I missing? Please note that any modification done to your system registry is your own responsibilty!!!
