Post by captaincookie on SP19 Runtime Zugriff auf lokales Dateisystem ^{CODESYS Forge talk (Post)}
Hallo, das konkrete Problem konnte ich seither leider nicht lösen, allerdings habe ich mit SP19 Patch 4 einen Workaround gefunden, der zumindest für meine Anwendung funktioniert: Zunächst besteht das Problem nicht für alle Funktionalitäten gleichermaßen. Die Anzeige einer .bmp oder .tiff-Datei im Visu-Elementtyp Bild beispielsweise funktioniert aus dem lokalen Dateisystem. Die Anzeige von .cnc-Dateien in einer Tabelle dagegen nicht. Allerdings funktioniert das wiederum, wenn der Dateipfad in den Ordner der PLC führt, genannt '_cnc'. In der PLC wird dieser Ordner über den Pfad _cnc/ erreicht. Auch lohnt es sich einen Blick in die PLC Config-Datei zu werfen und ggf. Anpassungen vorzunehmen. Einzelne Einträge definieren Zugriffsrechte und ähnliches. Die beschriebene Lösung ist nicht sonderlich schön und es erklärt das Problem nicht. Vielleicht kann das noch jemand anders beantworten.

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.

Change the actual time of your PLC. How to do this sometimes depends on the PLC you use. Please contact the vendor of the PLC to get this information. Or see the following example for using CODESYS date and time functions: https://forge.codesys.com/prj/codesys-example/date-and-time/home/Home/

Post by blitz on Latch alarm variables from the PLC runtime ^{CODESYS Forge talk (Post)}
Hi, I have a question. Does anyone know a way to change latch alarm variables from the PLC runtime? In the help there is a method described: https://content.helpme-codesys.com/en/libs/AlarmManager/Current/Interfaces/pou-IAlarm3/SetLatchVarValue.html but I don’t know how to use it correctly.

Post by simotion on Pointer to Softmotion axis ^{CODESYS Forge talk (Post)}
In my projet I use Softmotion. There are several Softmotion axis (type SM_Drive_Virtual). In the Global Variable List I have an array of pointers to the adress of the Axis. Axis : ARRAY[1..iMaxCntAxes] OF POINTER TO AXIS_REF_SM3 := ADR(AX01_Axis), // [1 ADR(AX02_Axis), // [2] This works, but when compiling I get the message : . [WARNING] E3D: GVL Device: PLC Logic: Application: C0564: A reference to uninitialized variable AX01_Axis is used for initialization of Axis. Accessing the uninitialized variable may result in unexpected behavior. [WARNING] E3D: GVL Device: PLC Logic: Application: C0564: A reference to uninitialized variable AX02_Axis is used for initialization of Axis. Accessing the uninitialized variable may result in unexpected behavior. Is there a way when initializing to force the hardware (softmotion axis) to first initialize and then the Global Variable List?

Post by alez on CANopen safety , SRDO error behavior ^{CODESYS Forge talk (Post)}
I have a project in which there is a Safety device in CANopen, and the PLC interfaces with it as Master. I would like to understand if it is possible to set the behavior in case one of the SRDOs that I receive from the slave is no longer received. From what I have seen, if the SRDOs are not received, the CANopen safety status becomes "Not in progress" and the mapped variables freeze at the last value detected. I want to understand if it was possible to set the variables connected to the SRDOs to take a default value (e.g. zero) in the event of a CANOpen error during reception.
