JRiddington Posted June 12 Report Share Posted June 12 Hi there, Any advice welcomed. I need to upload a program using UniLogic. I have tried connecting via USB and via Ethermet and Unilogic doesnt seem to see the controller? Any techniques or anything im missing? The upload button at the bottom of the menu just remains greyed out. Thank you Quote Link to comment Share on other sites More sharing options...
DanT Posted June 12 Report Share Posted June 12 Hi; One issue can be mis-matched versions between UniLogic on your computer and the Version used to download the original program into the PLC. ( UniLogis is VERY Picky about this The versions MUST MATCH ) What version of UniLogic OS is in the PLC? UniApps -- About What version of UniLogic are you using ? If necessary you can download older versions of UniLogic and install them - Yes you have to uninstall the current version first. ( To have Multiple versions of UniLogic available on your computer, see the posts elsewhere in this forum) DanT Quote Link to comment Share on other sites More sharing options...
JRiddington Posted June 12 Author Report Share Posted June 12 Hi Dan, Thanks for getting back to me. Aha ok yes i could be something to do with this, i hadnt thought of that. I think you could be on the money with this. I am running version 1.33.236 of Unilogic Studio. No idea what version was used previously however as it is a PLC we have acquired from an outside source. Id just like to upload the project in there now just in case we need to use it again. Ill have a dig and see if i cant find out what version number they used. I'd imagine it will be a much older version as i have only just downloaded Unilogic and the program in this PLC is at least a few years old.
