Post by fraccaroli on New Codesys Library Dependencies ^{CODESYS Forge talk (Post)}
Hello, you probably fixed in this meanwile, but I think your problem comes from dependencies of other libraries. I see in the Project column of errors the "caa types extern" and "caa fb factory", that both have dependencies. Try to check there. Regards, Francesco

Hi, you should have 'CODESYS Installer,' there you can manage your packages and installations. The version number looks like a softmotion package, try to install it. Or repair your whole installation with the CODESYS Installer.

If I want to display level in the tank, what's usual approach? Is there tank or vessel element I can use? I see there is bar display, but I can't make it fill the shape I need.

I'm not sure I understand what you're asking, but I don't believe a function block with this behavior exists in the default libraries. I think the best solution would be using multiple and/or blocks or make your own function block.

Go to Online>Communication Parameters...>Gateway>TCP/IP> Click on "New..." and reestablish your connections with whatever IP address and set up information you have. Bypass whatever is necessary as you may have to redownload to the PLC.

Maybe it is better to use Interfaces to access the objects instead of pointers. But besides that, is "read_obj_ptr" a method? If yes, you need to call it, so add brackets behind the method call: read_obj_ptr();
