Post by garmusd on Raspberry Pi 5 GPIO not working. ^{CODESYS Forge talk (Post)}
Hi, Codesyscontrol 4.13.0.0 Raspberry Pi5 64bit with latest updates. Cant get working GPIO - no output and no input. SPI/I2C not tested. GPIOs B+/Pi2, Input/Output is set in the parameters, assigned variables int the Mapping. Absolutely no reaction. Do I need to configure anything else to make it work? Thanks!

Post by rh-pk on v3.5 SP19 - Modbus TCP Devices - Channel Limit? ^{CODESYS Forge talk (Post)}
Hello jacobwago, I believe that the limit is fixed in the editor, but not in the driver package. There seems to be no link between the driver setting and the editor. Otherwise, I don't know why the input (>10) is blocked, but the function is available. Unfortunately, I cannot offer you any other solution apart from the one mentioned above. Kind regards

Post by davidmic on What is this ST syntax? ^{CODESYS Forge talk (Post)}
I found some structured text code which contained this statement: bHidden:= TRUE(*NOT _somevariable*) I haven't seen TRUE() used like a function before, and I also haven't seen the enclosing asterisks * * before. What do they do? (sorry if this is a duplicate question, I don't know what words to use to search for this syntax)

Post by dekelec on TrueType font problem ^{CODESYS Forge talk (Post)}
Initially I had the same problem in CoDeSys when selecting a newly installed TTF font, while CoDeSys was running. I solved it by closing Codesys and running it again to restart the initialization process. After that, using the new font did not pop up errors. I also had cases with files that had a ttf extension, but were actually not TrueType.

Post by phoward131 on Alarm filtering latch variables ^{CODESYS Forge talk (Post)}
I am having the exact same issue and was wondering if you ever found the problem? The sample program does exactly what it's supposed to with filtering but when I implement it the exact same way in my program, the alarm list just goes blank when I attempt to apply a filter.

Post by ellocco on FUP: Ausgang eines existierenden Blocks mit dem Eingang eines existierenden Block verbinden ^{CODESYS Forge talk (Post)}
Ist es unter dem FUP-Editor von CODESYS V3.5 SP18 möglich, eine Leitungsverzweigung mit einem existierenden Block (z.B. AND-Glied) zu verbinden? Oder den Ausgang eines existierenden Blocks mit dem Eingang eines existierenden Blocks (z.B. OR-Block) zu verbinden? Gibt es dazu Vorschläge?

Post by lsislsis on SIGABRT Error ^{CODESYS Forge talk (Post)}
After many tests i see that problem comes when serial communication established for modbus rtu. If the slave device not connected we don't see the exception. If the slave device connected at serial port then we have exception about 1 hour after startup and every 10 or 15 minutes. Any suggestion?

Post by sigurdrb on Codesys SP20 and professional developer edition ^{CODESYS Forge talk (Post)}
Hi, I updated codesys IDE to the newest version, but I lost the "professional developer edition" in the process. It still works fine on the older version I have been using previously. Do you know what the easiest process for getting the same integration in the newer version? It is only the GIT integration that I really miss.

Post by gseidel on Strange problem with the ‘MC_SetPosition’ function ^{CODESYS Forge talk (Post)}
Hi Gustavo, can you reduce the problem to a project that reproduces the issue without the real servo drives? (You could set the servo drives to virtual and strip away as much as possible from the application.) If you can attach a project, we will have a look. Best regards, Georg

Post by jeffersonhui on SP20 Visualization Element Dynamic Colors ^{CODESYS Forge talk (Post)}
I am using Codesys SP20 patch 5 and in a visualization element, the "Color variables" section does not have a section to set up dynamic color values linked to variables. In a previous version (SP18), I get the option to add variables for Normal & Alarm state colors. Does anyone know how to get the dynamic color variables to work?

Post by cellohorst on File Creation Issue ^{CODESYS Forge talk (Post)}
Nope! The file path is $$PlcLogic$$ and NOT $$PLCLogic$$. Otherwise a new folder ('PLCLogic') is created (at least with a linux rt - like raspberry or compute module) with the new file in it if you open the file with eFileMode := FILE.MODE.MRDWR. That is a bad bug that I'll report right after this comment.

Post by wayne-riesterer on Assignment Efficiency - Repetitive Assignment vs IF statement ^{CODESYS Forge talk (Post)}
Thanks for your responses. I like to write the leanest possible code that I can because it makes it much easier to read/maintain/debug. OR_ELSE is what I was looking for. I wasn't sure if CodeSys short-circuited evaluation and I didn't realize this operator existed. Thanks!

Post by eschwellinger on Codesys Network driver install for Codesys Control RTE x64 ^{CODESYS Forge talk (Post)}
Yes, either adding in the CODESYSContro_User.cfg because the driver will no longer appear in the list or type the name from the documentation in the configuration and when the gray check mark appears, the driver is also installed. It is just not selectable anymore.

Post by benemenn on Type mappings in Datasource ^{CODESYS Forge talk (Post)}
Hi! I am trying to achieve the same issue. Has there been a solution? I can create the mapping, and map the local variable, but somehow the object does not update. Furthermore, i have an issue where codesys doesn't let me set ReadWrite accesses to the variables in the "Type Mapping" place. The access will simply not be set. Has anyone ran int that issue?

I want to pass the FB for an AXIS_REF_ETC_SoE_Standard to the visualization and display live axis data in the visualization.

Post by snguyen on Atomic and Shared memory? ^{CODESYS Forge talk (Post)}
Hi, I've read that you can perform Atomic instructions like AtomicReadLInt on variables. However, I'd like to know if this uses stdatomic internally. My main question is : Is it possible to share atomic types in shared memory with CodeSys. If so, what types should they be declared as? If not, are the atomic functions lock-free or does it use a mutex?
