Post by mariusz997 on Visualisation - internal error ^{CODESYS Forge talk (Post)}
Hi everyone. I try to reach Codesys but I have problem on the beginning. I use Codesys 3.5.18.60 and 3.5.18.30 . On both version I have this same problem - when I create new standard project with controller Control Win v3 x64, empty PLC program - I compile it and everything is ok. But when I add visualisation without any elements and compile it - I get: ~~~ ------ Build started: Application: Device.Application ------- Typify code... Generate code... Generate global initializations... [WARNING] SortingStation: HMI Device: PLC Logic: Application: Missing element configuration. Element may not be usable.
