Post by talhaali on Can't read Alarm Class from Alarm Storage ^{CODESYS Forge talk (Post)}
Hi, I am trying to access active alarms in code(As alarm count variable updates only when we go to to alarm table frame in visualization). I wrote following code but it is not working: VAR iCountActiveAlarms : INT; parritfActiveAlarms : POINTER TO ARRAY[0..0] OF IAlarm; itfAlarmManagerClientAll : IAlarmManagerClient; END_VAR AlarmManager.g_AlarmHandler.GetActiveAlarms( itfAlarmManagerClient :=itfAlarmManagerClientAll, iCountActiveAlarms => iCountActiveAlarms, parritfActiveAlarms => parritfActiveAlarms); The Value is always 0. Please help.

Post by installwhat on C0077 on one machine but not another ^{CODESYS Forge talk (Post)}
It doesn't load differently codesys seems to be behaving differently. Original version of ethercat master in project archive is 3.5.15.50, compiler is 16.4 as is codesys I'm using. It builds fine in vm and not on local machine. The reason is not obvious. It builds on local machine with ethercat master at 3.5.16.0. I'd really appreciate advice

Post by steven-schalm on Github Actions CI/CD tasks - development topic ^{CODESYS Forge talk (Post)}
hello kevinrn, I've been looking for a solution to the CI/CD issue for a long time. Briefly about me... I am 32 and software architect for Codesys V3 and fullstack dev for web (VueJS, NestJS) in a small company in Erfurt (Germany). https://www.rex-at.de/. Through my web part, we already have CI/CD running well via GitLab (YAML-based configuration file (.gitlab-ci.yml), which defines which pipelines and jobs are executed when certain events occur) with everything you know. Stages for npm packages - prepare (GitVersion, npm install or whatever) - build (vite, tsc or whatever) - testing (vitest, jest or whatever) - deploy (npm packages) And similar for monorepo's or backend services (in NestJS) as DockerImages. For Codesys we have been building an OOP framework for years (~50 libraries now), which is currently managed via SVN and a specially written Svn-Watcher (in Python) gets commits and runs and builds everything together and deploys it to an FTP server and network drive. Why do we still have SVN? Because we are unfortunately still tied to the safety integration of Codesys and can therefore only go to SP15 at most with our controller/Eckelmann. But soon there will be an update and there will be no more obstacles to using Git. Hence my questions: 1. the basic idea is to run a local Windows Runner on some machine? 2. install Codesys on the machine where the runner is running? 3. powershell & python scripts are then used to execute builds (compile, build, sign libraries) & deploys? 4. can the Github action also be used in GitLab? ChatGPT has already told me that it's not the same, but it doesn't hurt to ask. Do you have any ideas on this? Greetings :D

Hi Tobthi, Do you have the eds file of the camera? I usually load first the eds file and then add the device to the Ethernet/IP scanner.

You can download the missing libraries by clicking on the "Download Missing Libraries" button. However, if you were unaware of this and accidentally downloaded the latest version of the library from the Library Repository, you may need to uninstall it first to avoid conflicts.

Post by tk096 on SMC_ReadNCFile2 is always busy ^{CODESYS Forge talk (Post)}
Hi, do you process the sentences subsequently? If not, the function block fills the sentences (queue) and waits for the sentences to be processed, so that new sentences can be read and filled to the queue.

Dear Tim, This is the missing link for me. I was not aware of the fact that the docker container is claiming the smallest possible license. Now the serial number makes much more sense. Thank you

it should be something like: fbWebClient : WEB_CLIENT.WebClient; You need to use the "Namespace" of the library, not the name of the library itself.

Hi eschwellinger, I changed the name to tap2 due to network issues with Debian (I don't know why it changes the tap0 IP every time the program restarts). Anyway, I think the tap name doesn't affect the connection.

the project has only one OneWire Master - so if you add the setting "PlaceholderFilePath.2=/sys/devices/w1_bus_master2, $OneWire2$ to the config file it will fail and the Ethercat task will be blocked by the OneWire Master readings?

Post by ihatemaryfisher on Sorting array of any-sized structure ^{CODESYS Forge talk (Post)}
With that I could make an array of varying size, but would still have to define the array type in the function's declaration VAR_IN_OUT stArray: array [*..*] of <pre-defined data type> END_VAR I wanted a function that could take an array of any type (e.g., a structured VAR) as an input. That way I could call it in multiple POUs to handle different arrays structures.

Post by voffi on Converting UINT into bytes and converting 2Bytes into UINT ^{CODESYS Forge talk (Post)}
There are some ways. One is to use SHR and SHL and it depends on your byte order in the data array. For Motorola byte order: PROGRAM PLC_PRG VAR u : UINT; byte_array_in : ARRAY [1..8] OF BYTE := [16#11, 16#12, 16#13, 16#14, 16#15, 16#16, 16#17]; byte_array_out : ARRAY [1..8] OF BYTE; END_VAR u := SHL(TO_UINT(byte_array_in[2]), 8) + TO_UINT(byte_array_in[1]); byte_array_out[1] := TO_BYTE(u); byte_array_out[2] := TO_BYTE(SHR(u, 8)); If it's Intel byte order just change 1 and 2 in the array indexes.
