Hello! Did you ever solve this? I'm running into the exact same problem.

Post by cfam on Codesys Control for PLCnext SL, Bus not running ^{CODESYS Forge talk (Post)}
Good day I would appreciate it if you can give me some advice on how to fix my "Bus Not Running Error". I am Using Codesys 3.5 SP20 and Codesys Control PLCnext SL V4.12.0.0. Codesys control was installed on the device and I can log into it but it seems that it does not pick up the PLC or the IO attached (Please see attached Image). The Bus Cycle Task of the AXL F 2152 is set to Main Task and the "Always update Variable" is Enabled on each IO Module. My Main Task interval is set to 100ms and Priority is set to 0. I have tried other options and none seem to work. Your response to this issue will be highly appreciated.

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?

This is still a huge problem. Does someone know how to update the frame references (not manually for every frame-element...)?

Post by micik on Python scripting - print whole project tree ^{CODESYS Forge talk (Post)}
Hello, I have found a script for printing device tree in Codesys project. This script is available as code snippet as an exmaple for using Python in Codesys. However I feel main documentation is lacking. For example, where can I find that object has "is_device" attribute? Code examples are given here: https://content.helpme-codesys.com/en/CODESYS%20Scripting/_cds_access_cds_func_in_python_scripts.html However, I have a question how to print the whole Project tree and not just devices? Of course I need to remove check: if treeobj.is_device: But simply removing this test condition will not produce what I want. I need to print PLC Logic, Application, ad other nodes in the Project tree. Where to find this documentation?

Post by ivanh on kepware minimun privilege ^{CODESYS Forge talk (Post)}
Hello everyone, I’m integrating Codesys with Kepserver using the Kepware driver for Codesys, and I need to configure a user account with the minimum necessary privileges to read and write to the tags on the PLC, without using the internal OPC UA server of Codesys. However, despite not assigning the Modify permission, Kepware still allows writing to the tags. What are the minimum required permissions to ensure that writing is only allowed when necessary, and how can I prevent other permissions from being overridden? Any guidance would be greatly appreciated.

Old question but since I stumbled on it others might. He probably added the function he wants to be called before using the "add event handler". If you don't add it first they will be created with the correct params.

Post by paulorb on STRUCT AT %MW1000 ^{CODESYS Forge talk (Post)}
Hi I am trying to use STRUCT to parse commands from Modbus/TCP, Modbus client will fill the bytes related to a specific command (type, parameters), then PLC (Codesys) will access the command parameters. A STRUCT will simplify a lot the process of parsing the data, so I don't need to parse byte per byte, address will be mapped to a struct and I can use it for parsing the data. From what I understood, the compiler does not allow me to specify the location of the struct for a %MW register. VAR_COMMAND AT %MW1002: structGenericModbusCommand; This will throw: Bad declaration, use '%ML' for 'structGenericModbusCommand' variable But If I change it to %ML, when you go online you see that it is actually allocating the struct in another memory address. When we go online, on GVL we can see: VAR_COMMAND. structGenericModbusCommand %ML1002 commandType COMMANDTYPE %MB8016 ... %MB8020 I am not specifying a pointer or a reference it is a struct type, why is it mapping to a %MW location (random one). How can I control where it is mapping to? I need a consistent way to map STRUCT to specific modbus address. Is it possible? Thanks, Paulo Note I am using a Codesys OEM: Schneider Machine Expert Logic Builder (M241)

Post by mubeta on STRUCT AT %MW1000 ^{CODESYS Forge talk (Post)}
This is normal and correct since in CoDeSys static addressing of variables uses the IEC method. A LONG tag has the size of 8 bytes, so %ML0 coincides with %MB0 ... %MB7; %ML1000 with %MB8000 ... %MB8007. (Similar reason for word and other formats). Also the reason the compiler won't let you map the structure to a %MW depends on the fact that the individual base elements are manipulated to 64 bits regardless of the smaller size. That said, it makes me strange that you cannot write a parser without making use of static memory allocation.

I think you have already up and running an Edge on the host ( not in the container) please uninstall that edge, then it should work.

Post by shawn-plc on Return value from a tag given a string literal ^{CODESYS Forge talk (Post)}
Good afternoon everyone, I am looking for a way to return a value given a string tag path. I put together a pseudo-example to illustrate my use-case and was wondering if anyone in this forum can help. The function fnValueFromTagPath is the function I am looking to either create or use from existing library. I would greatly appreciate it. Please see the attachment for additional detail. -Shawn
