Post by smartcoco on Add visual background FB blocks. ^{CODESYS Forge talk (Post)}
Can you add a background FB block to the visualization page, and loop through this FB block when the page is in display mode. This FB block requires two more functions, one for executing when the page is displayed and the other for executing when the page is closed.

Post by nathant on Can't open online view of FB instance from code editor, only from Device/POU windows ^{CODESYS Forge talk (Post)}
Hello, The title pretty much says it all. When trying to open a FB from the CFC/Ladder/SFC editors while online, the FB does not open in an online view of that specific instance. Instead, it opens an offline view with '???' shown for the value of any variable. This makes debugging extremely cumbersome, as I have to find each FB in the POU window and select the specific instance I am trying to view. Anyone know the cause/solution for this? Thanks.

Post by ph0010421 on Stack overflow with really simple function ^{CODESYS Forge talk (Post)}
Hello I wouldn't call an FB from inside a FUN; it feels wrong to me. I have had something similar. Try declaring the FB instances as GlobaVars rather than the instance memory.

inside the fb, use the reflection-attribute and get the instancename includibg whole path.when im right, the applicationname will also reflected, if yes. you have to trim it. https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_pragma_attribute_instance_path.html

Post by jari-koivuluoma on Problem trying Net Base Services 3.5.15.0 TCP connection ^{CODESYS Forge talk (Post)}
Solved. Just in case that someone else is now to this also. It seems that the xDone of the TCP_Connection FB goes true once client disconnects and then you need to reset the FB by setting the xEnable to false.

Post by timvh on FB string and naming ^{CODESYS Forge talk (Post)}
I see, you want to initialize the FB. To be able to initialise it like you described, you need to add the FB_Init method to your FB. (right click on the FB, select add object --> method). Then press the arrow down, to select the FB_Init (overwrite default implementation). In the VAR_INPUT section of this method, add the variable --> Tag : STRING; Then in the code section of this method add: THIS^.Tag := Tag; // copy initial value to local variable in FB Search Google if you want to know more about FB_Init. PS, reflection + instance path, is also an option if you want to get the full name of the instance (path) of the Function Block. See: https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_pragma_attribute_instance_path.html

Post by paulorb on FB Factory example ^{CODESYS Forge talk (Post)}
I am trying to use FB Factory (to dynamically create FB), I am looking for documentation the only thing I found is this page: https://content.helpme-codesys.com/en/libs/CAA%20FB%20Factory/3.5.17.0/Factory/fld-Factory.html I am trying to find the examples, I search on the installed folder, I have the impression that it is no longer installed as part of the CODESYS installation. Where can I find it?

Post by pernockham on Is there a pragma for init/instantiation of local variables in FB (like in Methods) ^{CODESYS Forge talk (Post)}
Im using a pointer as input for a FB and for convenience I like to use 'referenced' variable internally. I use this setup in methods which works because internal variables are instantiated for each call. In a FB these variables are instantiated and initiated for the first call only. Is there a pragma/attribute available that changes this behaviour to mirror a 'method'-call?
