Post by androidzz on Json Builder problem? ^{CODESYS Forge talk (Post)}
Dear reader, I am using the codesys JSON utilities SL, 1.9.0.0 library. And then specifically the FB JSONBuilder. I need to create a main object with at least 2 objects in it. The first object is no problem, but I cannot insert the second object into the main object. See attached my code and the result I get. I am assuming that I am doing something wrong with the parent index but have tried a lot and can't get it done. Kind regards, Rob

Post by snhatton on Retain memory change to ZERO ^{CODESYS Forge talk (Post)}
I think more information is needed to help solve the issue. Can you list the exact steps to reproduce the issue? What version of Codesys are you using? Did you add a persistentVars object to your project? I would recommend browsing all instances of the retain variable to see all possible writes to the variable in question.

Post by timvh on Limiting Memory Access of an Array to Within its Bounds ^{CODESYS Forge talk (Post)}
Add the object "POU for Implicit Checks" to your application, then select "Bounds check". This will create a function which is automatically called each time an array is write accessed. In the function you can handle "out of bounds" situations. By default it will be limited to its lower or upper bound.

Post by climblinne on Calling OPC UA Methods from UaExpert ^{CODESYS Forge talk (Post)}
Hello, I hope someone could help me. I installed the newest Codesys 3.5 SP 20 Patch 1. When loading the demo files from @i-campbell I can upgrade them to the latest version and everthing works on the OPC-UA client side as expected (object "a" is visible, I can use the "ExampleMethod"). Now I * remove the "Information Model", * delete the "OPC_UA_Symbols Objects", * Add "Information Model" again * add "TestRootObjectType" again and "Generate IEC declarations" * and search for mapped instances (to get instance "a" again) Very good still working as expected. Now I delete the OPC_UA_Symbols and add it again referring to the "objecttest" from 16.9.2020. Also I redo the steps from above. The result is now, that I can't see the "a" object in the "Root/Objects" folder. Why ist this and how can I make it running? I think, it could may be a different version of the UA configuration file. I tried to build my own model definition files and got the same problem (but I am really not an expert). When someone has a actual model, which is also running in the actual Codesys I would be very grateful. Or even better, how to make the correct model in e.g. UA Modeler SW (I followed the description https://documentation.unified-automation.com/uamodeler/1.6.0/html/howprojnet_sec.html).

Post by schnepper on Minor UI bug: cannot create SFC POU after creating a Function POU ^{CODESYS Forge talk (Post)}
After creating a Function POU, it is not possible to then create an SFC POU. Steps to recreate: * Create a new Function POU. SFC is not allowed for Functions, so SFC does not show in the Implementation language dropdown. * Click Add Object -> POU... Function is selected for Type. * Select Program * SFC is not present in the Implementation language dropdown

Post by swe-hob on call of a method of a function block in another program ^{CODESYS Forge talk (Post)}
Hi, Let's assume following: PRG_1 fb_1 : fbExample1; fb_1.method_1 do something... PRG_2 fb_2 : fbExample2; fb_2.method_2 if xTest then PRG_1.fb_1.method_1(); end_if; Is there a reason why runtime hangs when I call the method_1 in PRG_1 from a method in PRG_2? Both programs run in the same task. No chance that any other program calls the method. What I practically do there is that in the program PRG_2 I add a structed object into a buffer. In PRG_1 I just process the items in the buffer.
