Post by vamsi on How to configure gateway for programming RPi 2B using Codesys ^{CODESYS Forge talk (Post)}
I am using a Raspberry Pi 2B. Installed Codesys V3.5.20.1 64-bit and installed 'CODESYS Control for Raspberry PI 4.12.0.0' I am able to install the packages using the 'Update Raspberry Pi' option, but when I try to log into the RPi, in the Device tab it says 'Sacn fail. Please checl that the gateway is running and that its settings are correct'. My setup looks like this. I connected my RPi to my company LAN and also my laptop to company LAN (using HP Docking station). This setup worked when I installed 'CODESYS Control for Raspberry PI', but now I donot know how to configure the gateway. Could anyone please help me in finding what I have to enter in the gateway configuration? Thanks, Vamsi.

Post by trent on Automation server - trends stop recording - need to manually reconnect ^{CODESYS Forge talk (Post)}
Hi All, I use the analysis page in automation server to capture historical trends from my PLC - i only sample one point per hour but it does the job (for now) One issue I have is I often log on to analysis page to find the system has stopped recording trends from my PLC. To fix this, I need to choose "state information" in the "List view" under PLC and click "Reconnect" When I do this I see my variables listed under "parameters" under "PLC Details" start updating again and the trend in Data analyzer continues to update. My Question, Why do I need to manually reconnect? Is there a way to get automation server to automatically reconnect to the PLC so I continue to capture data from the PLC? Regards, Trent

Post by mahmutbeyaz on Create a Motion Profile ^{CODESYS Forge talk (Post)}
Dear All, I hope first to get notice and somebody answer my question. How can I create a motion profile with the axis following it (once or periodically)? As my research shows, Schineder has a UI-based (Motion Sizer) program that helps create a motion with different configurations, which is Codesys-based. I need to create a motion profile based on position, changing the speed. (i.e., 0-300mm moves with 300 mm/s, 300-400mm moves with 500 mm/s, 500-800mm moves with 1000 mm/s, and 800-0mm moves with 2000 mm/s). MC_PositionProfile does it time-based, which is not working for me as the axis may not stabilize the position in time, which may cause a big failure in the system.

Post by karol-abktech on Raspberry and problem with runtime ^{CODESYS Forge talk (Post)}
Hi, My problem is with raspberry pi 4 with 2 GB ram,. Install codesys is correct but runtime works only few seconds or I can connect with device few seconds. I can ping raspberry and in system info I can see " !!!! Warning: no runtime license - running in demo mode(~2 hours)" but it is 2 minutes after runtime. When I press Start runtime I have another few seconds when I can connect to raspberry. After this time I couldn't find device. Of course, reapet start runtime works every time on few second. Raspberry is new and works with fresh install raspberry os 32 bit. Where should I start looking for solve of my problem ?

Post by janderson on Ethercat scan for devices not picking up EL7041 as a softmotion axis ^{CODESYS Forge talk (Post)}
it appears that the different revisions have different PDOs. I am currently trying to use the rev25. I have tried to use the rev24 (the device repository entry not from 'scan for devices') and i keep getting 'invalid output mapping' or 'invalid input mapping' in the ethercat log. I cant even get the bus to run from the device description that comes from 'scan for devices'...

Post by aott33 on Webvisu NO load ^{CODESYS Forge talk (Post)}
Thanks, I will check the PLC Log when the PLC is connected again. I will update my findings here. Since I don't have access to the Linux Panel PC at the moment, I tested inside my development VM with the same Linux OS. I have no issues or delays connecting to the WebVisu using my Linux VM. Two main differences: 1. My host Computer has a faster processor compared to the panel PC. 2. There are no devices connected in my dev environment. I will continue testing when I have connection to the panel PC.

Post by r-niedermayer on OPC UA subscriber not operational ^{CODESYS Forge talk (Post)}
Hi. As far as projects in "old version"s are concerned, these can be upgraded to newer versions at any time. To do this, the device must be updated accordingly and the copilers and library versions must be adapted. You can find instructions on how to proceed in the online help/FAQ: https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_changing_compiler_version.html https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_cmd_update_device.html See also 4.3.22.4 "How to open an Example Project" within the following pdf for more details on the single steps: https://forge.codesys.com/lib/counit/tickets/_discuss/thread/3e991befbc/ca97/attachment/Public%20FAQ-v13-20240610_075228.pdf Regaring your OPCUA connection state always showing just "DISABLED", without knowing both sides of the assembly in detail, one can only approach the problem theoretically. We can give a chekclist on how to proceed: Fist, please recheck the communication settings in the OPC UA connection function block to ensure that the server URL, endpoint URL, and other settings are correct and match the configuration of the OPC UA server. Verify that the OPC UA server is running and accessible. -You can try to connect to the OPC UA server using a separate client, such as UAExpert, to ensure that the issue is not related to the OPC UA server itself. Test the security settings in the OPC UA connection function block to ensure that the correct security policy and certificate are selected. If you are using a dynamic connection to the OPC UA server, probe that the connection settings are correctly configured and that the OPC UA client is able to establish a connection to the OPC UA server. Also, please loock into the log files for any errors related to the OPC UA connection function block, these should be listet there. The log files may also provide additional information about the issue and help you to further troubleshoot the problem. FYI - Please see https://content.helpme-codesys.com/en/CODESYS%20Communication/_cds_obj_data_source_communication_opc_ua_server.html: Her you can finde the Communication settings via OPC UA Server -> layout Browse Live Server: The client connects to the server and detects the existing variables and types. From Information Model The client reads the data structure (layout) of the OPC UA Server from the information model set here and as a result receives the information about available variables and types. A connection to the server is not required. The list contains the information models installed in the OPC UA Information Model Repository. "Read Connection" Settings from IEC Variable (option set): - The connection settings used by the device are not read here from the dialog, but at runtime from the IEC variable specified here. - For this possibility, please see the Using a Dynamic Connection to an OPC UA Server (https://content.helpme-codesys.com/en/CODESYS%20Communication/_comm_use_dynamic_opc_ua_server_comm_settings.html) The settings for the communication of a Client-data source to an OPC UA Server can also be dynamically configured from the IEC code and can also be changed at runtime. For such a purpose, a structure is available in the DatasourceOpcUAServer library (For a description of the OPC UA Server, there is one included in the standard installation of CODESYS, https://content.helpme-codesys.com/en/CODESYS%20Communication/_cds_encrypt_communication_data_sources_opc_ua_client.html)

When trying to connect to a Github repository in the Git remotes windows of Codesys, the user can be the account username or the account email, while the password is the Github token. (I know this is an old topic, but I lost some time figuring it out from the guides.)

Just verified the behaviour. Still is the same. It should be attached here. But I also tried the DCF-file with the axis in the lab with the real drive: The MC_Power block never goes out of busy. Had not time to investigate further, though.

Post by smartcoco on Dynamic object release issues ^{CODESYS Forge talk (Post)}
Dear, When I use "__NEW" to dynamically create the object "Object_1", and assign this object "Object_1" to another object "Object_2". At this point, I use "DELETE" to release the object from "Object_2". At this time, I cannot judge whether the object has been released normally through "Object_1" (in fact, the object has been released theoretically). Thanks for you help.

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 markushunter on Different behavior between the "Start" button in the IDE and the Cmp function "AppStartApplication()" ^{CODESYS Forge talk (Post)}
One workaround is to create a second application which is started after the rested of the main application. The second application starts the main application after time x and is rest after done start of the main application. No problems during the fieldbus re-start by this workaround.

Post by mmpl on Array to String ^{CODESYS Forge talk (Post)}
I would like to create one large JSON string from an array of objects, where each object contains a value. My current approach involves using a for loop and string concatenation, but with 20,000 elements in the array, this method takes almost 7 seconds and negatively affects the PLC scan time. Is there a more efficient way to accomplish this?

have a look at UNIONs. With a union you are able to write single bytes to the same adress area which belongs to a float variable at the same time. I like to do a lot of convertions belonging to interfaces and fieldbus in this way, f.eg. word / byte swapping etc.
