Hello, Im running into a problem after moving from SP18 to SP20 or SP21. After the update I have an error with the TextFieldInmputHandler.VariableWritten which is implemented if de visualisation part of my software. The interface seems to have changed. I cannot find the new implementation. Does anyone know how to solve this issue.

Post by josealb2000 on EL6910 as a PROFIsafe F-Host in Codesys ^{CODESYS Forge talk (Post)}
Interested. I can see the EL6633 Profinet Controller can be added in Codesys to the EK1914 or EK1100, and then ProfiSafe devices can be added as the F-DI8/F-DQ3 ET200eco PN. Im unsure how to configure the telegram to the EL6910. Have you been able to make this configuration? EL6910 Manual shows a way but only using TwinSafe.

Post by snguyen on Any ways to prevent Infinite scroll when moving an object to the left or top edge? ^{CODESYS Forge talk (Post)}
I've been making few HMIs and I'm starting to get annoyed that whenever I try to align an object to the left or top side of the frame, it quickly scrolls into that direction infinitely. Is there a way to prevent that?

We used this with shared memory codesys. and work. OpENer is an EtherNet/IP™ stack for I/O adapter devices; supports multiple I/O and explicit connections. And we adapt this also for Implicit message. But for arrive to the end we spend a lot of time. :-(((

Post by timvh on Persistent Retain Variables Not Visible in Online View (WAGO PFC100 + CODESYS) ^{CODESYS Forge talk (Post)}
It is a known issue. It only happens with CODESYS and Wago controllers and the Persistent Variables. It seems related to using 64 bit variables in the PV list (e.g. LREAL). Internally in the PLC everything works okay. It is just a monitoring issue.

Now that SP21 is out, what's the answer? I want to get a pointer to the TxPDO and RxPDO structs. I can generate a STRUCT declaration from the ESI file with a bit of Python. I just need to get the pointer from the ETC_Slave.

Thank you for your answer. The build > Generate Code start the code of the application but does not modify the compileinfo. I work with .projectarchive to avoid this kind of problem. I would like to have the possibility to modify the compileinfo by myself so I can indicate the losses information.

Hallo an alle, ich schaue mir gerade ein paar 22kW Wallboxen an: https://shop.einfacheauto.de/collections/22-kw-wallboxen Mir wäre vor allem wichtig, dass die Kommunikation per Modbus gut funktioniert. Es werden zwar ein paar Wallboxen gelistet, die Modbus ermöglichen, trotzdem wollte ich euch nach Erfahrungen fragen, welche Modelle in der Hinsicht besonders problemfrei funktionieren.

Hello, Basically, everything is clear to me. There's still the issue of a TimeProvider for an external device. This may be a stupid question, but I can't find this package. And of course, the question is, can the RPi machine be an external provider? Has anyone tested such a solution?

Post by althafu on Codesys v 3.5 to factory IO ^{CODESYS Forge talk (Post)}
I have been following the steps shown in the RealPars video to connect CODESYS with Factory I/O. The connection works correctly when I use Ladder Diagram, but when I try the same simple input–output logic in Structured Text, the simulation does not behave as expected. Has anyone experienced this issue or knows what might be causing it?

Post by scrisp on Source code changes since last download ^{CODESYS Forge talk (Post)}
Why does CODESYS 3.5 show the message “Source code changes since last download” even though I did not create or modify any new variables? When I go online with the PLC, it detects changes and suggests synchronizing, but nothing was actually changed in the project. What could cause this and how can I fix it?

Hi Reinier, I'm wondering if you managed to get this FB to work? I was just trying it, and found it not to work, I get an EMCY message in the CodeSys program under the Device Status, but the FB doesn't pick up any EMCY messages from the Bus. Cheers.

Post by gseidel on SMC_ERROR SMC_CGR_INVALID_POSPERIOD ^{CODESYS Forge talk (Post)}
Hi blitz, that usually means that the modulo period, when converted to increments, is larger than 2^31. (The bus bandwidth is usually 2^32.) What is your "technical unit", do you program in angular degrees? And what is the modulo period? If you want you can post the drive configuration (screen shot of the "General" and "Scaling/Mapping" page). Best regards, Georg

Thanks Georg for responding. I have followed the suggestion mentioned in the real time problem. However, it does not solve the problem. The weird part is, the robot stops at the same position randomly and it does not stop when I increase the speed of the motion.

Post by timvh on <Dereference of invalid pointer> ^{CODESYS Forge talk (Post)}
Yes, this can be fixed by setting the correct reference to the structure.... But by only the given information it is impossible to say what you did wrong. Maybe you can start by first creating an instance of the structure within the program to see how this works.

Hallo, kann mir jemand was zu dieser Fehlermeldung sagen: Mitteilung vom Gerät: “Alarm online change executed but license for Online Configuration Change not aviable!” Habe erst letzte Woche noch auf dieser Steuerung (PFC300, FW30) eine Programmänderung gemacht und hat alles funktioniert. Die Meldung kommt am Schluss, wenn ich einen Online change gemacht habe. Dann geht die Steuerung mit Ausnahmefehler auf Stop.

SysTimeRtc.SysTimeRtcHighResGet(pTimestamp := lstActualIPCUnixTime_ms); SysTimeRtc. SysTimeRtcConvertHighResToLocal(lstActualIPCUnixTime_ms,lstActualIPCUnixTimeLocal_ms); SysTimeRtc.SysTimeRtcConvertLocalToHighRes(lstActualIPCUnixTimeLocal_ms,lstActualTime_ms); F30_SysTimeRtcHighResGetLocal:= TO_ULINT(lstActualTime_ms); Dies hat immer die selbe Zeit in UTC. Wie bekomme ich eine HIGHRes Zeit in Millisekunden. Und diese Zeit nicht in UTC sondern mit der Zeitzone verrechnet..... Und reicht es die Zeitzone mit "SysTimeRtcSetTimezone" zu setzen oder muss die Zeitzone im Linux (PC) gesetzt werden ?

Post by dhumphries on CODESYS Download Issue ^{CODESYS Forge talk (Post)}
I had an issue when my organization installed some security software that blocked scripts. The installer would silently hang at the same point every time. I had to get a network admin to make some change to security software that wasn't immediately visible to me as a user to allow the installation script to run.

Hi, How do you create your SBOM in Codesys. I have been searching for this topic but couldn't find any useful information. I am referring to making an export list or all libraries used in the project. I have developed a python script that exports them, but I am open for ideas of beast practice
