Hi @eschwellinger Just wondering if there is any update when the Expression or part of it has no effect will be fixed? Also have the ability to open an FB when online and offline. It would also be great to be able to view the ST code block when online.

Hallo Ton, vielen Dank für den Tipp. Das Löschen der '.precompile cache’ Datei behebt das Problem. Beim nächsten Programmstart ist die Datei bei mir aber wieder da und leider der Fehler auch. Ich habe in codesys auch keine Einstellung zum automatischen Löschen der Datei beim Beenden des Programms gefunden. Ist bei dir der Fehler dauerhaft weg?

Post by thieulam on Codesys access to DICTIONARY OBJECTS of ethercat (CoE ) Servo Drive ^{CODESYS Forge talk (Post)}
Hello to all! How can I read or write, via my main code (ST), to the registers present in the DO of my ethercat CoE servo drive? These objects appear in the list of the INITIALIZATION page, and from here I can only access them at startup. How do I access it in run time from my main PLC_PROGRAM?

I have created an EtherCAT slave code and fixed two slaves (IDs written in the 0xF050 object dictionary). The module IDs are 0x1 and 0x101, respectively. It can be scanned normally in TwinCAT, but when scanning in CODESYS, it reports an error. Why is this happening？text in the second pic means 'device cannot be found in repository'

Hello, I have an OPC-UA server with an information model. For many values, there is a defined range (e.g., 0 to 100). If a client enters a value outside this range (e.g., 120), the StatusCode should change to Bad. How can I accomplish this? Any help is appreciated! Thank you in advance. Best regards, Christian Stiller

Have you received any feedback or found any solutions to the load problem. We are running into similar issues, even without codesys running the load avarage is above 1 meaning that it is to busy already without plc code running. Hope you might have some more insight.

Hi, I suppose that you are referring to the error code "SMC_FB_WASNT_CALLED_DURING_MOTION"? Starting of Softmotion version 4.15.0.0 the instance path of the function block that has not been called is logged into the device log. This might help you to identify why it has not been called.

Hi, i am interested in this thread and have tried a couple of the above examples in to determine remote webvisu access. I am having trouble getting the lastusage variable to refresh during runtime? It seems to only log the last usage at initialisation and that is it? how do i gain ongoing access to the time variable as the code is running? Thankyou.

Post by dkugler on User management ^{CODESYS Forge talk (Post)}
If the PLC is equieped with a USB socket it's possible to copy the user management file via IEC code to a USB stick and restore it at the new plc. The file is located there: /PlcLogic/visu/app_visuusermgmtdb.csv I use this to reset the user management to default in case of the customer has changed passwords and lost it.

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 jrsantab on Remote connection to ifm PLC & HMI ^{CODESYS Forge talk (Post)}
We have finally solved the problem. The version of the Gateway in the computer that worked (3.5.11.0) and the one that didn't (3.5.17.30) was different. We have three different Codesys 3.5 versions installed because we work with different controllers. I believe that, depending on the sequence you follow to install the versions you get a different Gateway version. To solve the problem you first have to disable the "obsolete" services. Open services, serach for (in our case) CODESYS Gateway V3 Version 3.5.11.0 CODESYS ServiceControl Version 3.5.11.0 I stopped the services and changed to Manual Start. Then you have to create the new services. In our case, from a Command Prompt session (cmd): SC CREATE "Codesys GatewayService Rigual" binpath="C:\Program Files\CODESYS 3.5.17.30\GatewayPLC\GatewayService.exe" and then SC CREATE "CODESYS ServiceControl Version 3.5.17.30" binpath="C:\Program Files\CODESYS 3.5.17.30\GatewayPLC\CODESYSControlService.exe" remember also to set them as Automatic Start!

Post by elektron785 on Dongle von Linux-Modul (ARM64) nicht erkannt ^{CODESYS Forge talk (Post)}
Ich hatte noch einmal Zeit das mit der Lizenz zu probieren und habe dazu über den Codesys Installer das Virtual Control SL runtergeladen und ausprobiert, aber leider ohne Erfolg. Zunächst habe ich "Docker_codesyscontrol_virtuallinuxarm64_4.13.0.0_arm64.tar.gz" aufs Board geladen und das Image mit docker load geladen. Mit dem Befehl docker run --rm -dt --name codesys --network host -v /dev:/dev -v /tmp:/tmp -v /run/udev/:/run/udev/ --device-cgroup-rule='c 13: rmw' --privileged 470a708f17a2 hab ich dies dann ausgeführt, aber das Problem, dass ich das Board im Netzwerk dann nicht finden konnte. Damit ich die Verbindung herstellen konnte, habe ich die Datei "DockerRuntimeStart.sh" so verändert, dass ich den Teil: -p 11740:11740/tcp \ -p 443:443/tcp \ -p 8080:8080/tcp \ -p 4840:4840/tcp \ gegen --net host \ ersetzt habe. Das Skript habe ich dann aufs Board geladen und bash DockerRuntimeStart.sh -i codesyscontrolvirtuallinuxarm64:4.13.0.0 -c codesys -H verdin-imx8mp- ausgeführt. Nun konnte ich in Codesys wieder eine Verbindung zu dem Board aufbauen, aber der Dongle wird leider immer noch nicht im Lizenz-Manager erkannt. Wie kann ich denn prüfen, dass auf den USB-Stick vom Container aus zugegriffen werden kann?

Post by ragarcia on Error while using UpdateConfiguredIPSettings to change IP address ^{CODESYS Forge talk (Post)}
Hello everyone, I am trying to change dynamically by code the IP address of a Weidmuller controller. So I am basically using IoDrvEthernet library to use UpdateConfiguredIPSettings function but I am getting constantly the 'INVALID_STATE' error. Even though I am following a procedure it should work: * First I added on the config file of codesys the following: [SysSocket] Adapter.0.Name="eth0" Adapter.0.EnableSetIpAndMask=1 Adapter.1.Name="eth1" Adapter.1.EnableSetIpAndMask=1 * Secondly I am first disabling the ethernet interface by using Ethernet_0.Enable = FALSE and then executing DED.Reconfigure. After that, I run the Ethernet_1.updateConfiguredIPSettings Code: Ethernet_1.Enable:= EnableDisable; Reconfigure(xExecute:= TRUE, itfNode:= Ethernet_1, xError=> ErrorReconfigure, eError=> ErrorCodeReconfigure); IF Reconfigure.xDone THEN ErrorCodeIP:= Ethernet_1.UpdateConfiguredIPSettings(IPAddress:= newIP, SubnetMask:= newMask, Gateway:= newGW); END_IF IF Reconfigure.xDone OR Reconfigure.xError THEN Reconfigure(xExecute:= FALSE); END_IF Ethernet_1.Enable:= TRUE; Reconfigure(xExecute:= TRUE, itfNode:= Ethernet_1); IF Reconfigure.xDone OR Reconfigure.xError THEN Reconfigure(xExecute:= FALSE); END_IF Can someone help me? Thank you. All I am trying is to find a way to change dynamically with code, the IP addresses of my controller (2 ethernet ports).

Post by sanacfu on looking for v2.3 libraries on v3.5.19 ^{CODESYS Forge talk (Post)}
Hi all, I'm new to Codesys and Wago but well versed in Rockwell. I've been tasked with upgrading old Wago 750-880 PLCs that run Codesys v2.3. All I was giving is the original PLC program in v2.3 and the currently running machine. I've spec out to what I believe is a suitable upgrade, the PFC100 2ndGen, 750-8111. As I'm rewriting this code on the Codesys I can't find the same library functions blocks for ethernet settings PLC functions. Currently I'm working on code to get/set the PLC ethernet IP address and HMI IP addresses from the HMI screen. One other function I'm looking for is a warm reset function to the PLC. When googling for this stuff I see a lot of code not in ladder logic. Are these functions now not available to implement in ladder logic? Where can I get more information on finding and implementing this functions? Do I have to buy a license from Codesys to use these functions? The PLC I ordered should be arriving in 2-3 weeks.

Post by kblundy on Change the Opening Position of the Dialog using VU.FbOpenDialog ^{CODESYS Forge talk (Post)}
I hope the community can help me with this. I need to use the Visu Utils FbOpenDialog to control the opening and closing of a dialog. I have the Opening and Closing working, but I can’t get the dialogue's position to be controlled. The code looks like this: PROGRAM OPEN_DIALOG VAR xOpenLatchSettingDialog : BOOL; TopLeftDialog : VisuStructPoint ; fbOpenLatchSettingsDialog : VU.FbOpenDialog ; END_VAR IF xOpenLatchSettingDialog THEN xOpenLatchSettingDialog:= FALSE ; TopLeftDialog.iX := 100; TopLeftDialog.iY := 23; fbOpenLatchSettingsDialog(sDialogName := 'visu_AlarmLatchSettings', xExecute := xOpenLatchSettingDialog , xModal := TRUE, itfClientFilter := VU.Globals.OnlyTargetVisu, pTopLeftPosition := ADR(TopLeftDialog)); CloseVisuDialog(sDialogName:= 'visu_AlarmLatchSettings'); ELSE xOpenLatchSettingDialog:= TRUE ; IF fbOpenLatchSettingsDialog.xError THEN xOpenLatchSettingDialog := FALSE; END_IF END_IF I can't seem to work out a way to make the values in TopLeftDialog.iX and TopleftDialog.iY be passed correctly in the call and for it to change the position of the dialogue box. The code is compiled, but the position has not been changed. Any guidance or suggestions for revising this code would be incredibly valuable. Your insights could be the key to solving this issue.
