Post by davidbo on How to allow a user to handle certificates without access to sourcecode? ^{CODESYS Forge talk (Post)}
With CODESYS V3.5 it is possible for a user to do the following things among many others. 1) Handling certificates especially move a certificate to the trusted folder. 2) Change password and create new users for OPC UA access However it requires access to the whole projects and its source code. Something you might not want to hand over to an end user for a stand alone product. Is there a way out of this problem?

Man, this was a long time ago. I think the problem probably stemmed from not loading the certificates from the client and the server on the server and client respectively in the correct manner. I believe I ended up getting around it just by removing all security on the server. In the end we did not move forward with that architecture so I never had to actually fix it.

I ran into a problem. Uploaded an example (https://content.helpme-codesys.com/en/CODESYS%20Examples/_ex_uacapi_example.html) After launch. on the emulator. I see that I am having problems: - UaExpert does not connect. There are many servers but no connection. - I can’t transfer the certificate from quarantine to trusted ones. There is some problem with creating the certificate. CS 19.2. If anyone has had similar problems, please give me advice. Thank you.

Post by nano on How to access to variable value through symbolic string name ^{CODESYS Forge talk (Post)}
i know, this is the reason for us either. PLC-Handler is to big, and only available with additional Contracts/Costs. OPC-UA is to slow for us. As described, there is a solution available, but im not allowed to post them here. i would prefer you send a message at codesys store by "have a question" or similar called. Not sure. Or, if an Codesys-Official Member allows to share that informations, i can give you the right hints.

Post by joosterloh on Anbindung an bestehendes SIMIT Modell ^{CODESYS Forge talk (Post)}
Hey also ich soll mit CodeSys 3.5 ein Modell erstellen, welches ich dann später mit einem bestehenden Modell in Simit anbinden kann. In CodeSys steht das Modell mehr oder weniger und ich wollte jetzt mal ausprobieren, ob ich die beiden Modelle miteinander koppeln kann. Übern einen OPC UA Server hat das auch alles geklappt. Allerdings hängt es jetzt an den globalen Variablen. Wie gehe ich da am besten vor? Soll ich die Variablen in CodeSys anpassen oder gibt es da einen Trick? Vielen Dank schon einmal im Voraus!

Post by ivanh on kepware minimun privilege ^{CODESYS Forge talk (Post)}
Hello everyone, I’m integrating Codesys with Kepserver using the Kepware driver for Codesys, and I need to configure a user account with the minimum necessary privileges to read and write to the tags on the PLC, without using the internal OPC UA server of Codesys. However, despite not assigning the Modify permission, Kepware still allows writing to the tags. What are the minimum required permissions to ensure that writing is only allowed when necessary, and how can I prevent other permissions from being overridden? Any guidance would be greatly appreciated.

Post by veneto on OPC UA Client ^{CODESYS Forge talk (Post)}
Ciao damian177, provo a chiederti un'informazione. Sul mio progetto Codesys(ver.3.5 SP17) non è visibile l'oggetto "Data Source Manager". Il PC con il progetto Codesys(client) è collegato via rete TCP ad un PLC Siemens1200(server). Sul PC con Codesys ho installato UAexpert(client) e riesco a vedere le variabili del PLC1200. Riesci ad aiutarmi a capire come mai non è visibile l'oggetto "Data Source Manager"? Molte grazie

Hallo zusammen, gebe es den die Möglichkeit SPS Shell Commands wie "Cert-Import" ins Programm einzubinden? ich habe versucht meine OPC UA Zertifikate über die sysFile Bibliothek vom Quarantäne zu vertrauenswürdig zu kopieren, was auch geklappt hat, aber das Zertifikat wird erst erkannt wenn ich die Steuerung neu starte. Ich habe mitbekommen das, dass mit der cmpPlcShell Bibliothek funktionieren soll, leider blicke ich bei der Beschreibung nicht durch. Hat da jemand eine Idee ?

Post by mm-sceg on Runtime geht sporadisch in Störung -> RaspiPi4 reagiert nicht mehr ^{CODESYS Forge talk (Post)}
Guten Tag, ich hab seit längerem das Problem, dass mein Raspberry Pi4 durch die PLC in Störung geht. Auf dem Raspi läuft eine einfache Software mit OPC UA server, InfluxDB und ein NodeRed-Server. (Und MQTT-Server) Daten werden von der PLC über OPC-UA an NodeRed übergeben. Es kann sein, dass der Raspi 2 Wochen läuft, dann geht die PLC in Stopp. Manchmal nur 2-3 Tage. Ein Neustart über Spannung aus & wieder an schafft Abhilfe. NodeRed wirft extrem viele Fehlermeldungen in kurzer Zeit. Wenn die PLC in Störung ist, kann man sich nicht mal mehr über SSH beim Raspi einloggen. Der Raspi ist aktiv gekühlt und im Normalbetrieb nicht überlastet. Ich hab einige logfiles mit vielen Einträgen die mir nichts sagen, eventuell hat hier jemand eine Idee wie ich dem Problem Herr werden kann :) Der letzte Datenbankeintrag von der SPS war am 11.11.2023 um 5:55:50 Uhr. D.h. danach muss die SPS gestorben sein. Siehe Raspi-Log im Anhang. Das LogFile von Codesys startet leider erst um 11 Uhr, weshalb weiß ich leider nicht. Vielen Dank schonmal

Post by khaledkhalil on OPC UA informationsmodell zu Codesys ^{CODESYS Forge talk (Post)}
Ich habe Modelle in SiOME hinzugefügt, eine Software zum Entwerfen von Knoten und zum Hinzufügen von Instanzen. und erstellte eine resultierende XML-Datei. Ich habe versucht, die XML-Datei über das OPC UA-Informationsmodell-Repository in Codesys zu importieren. Das Problem besteht darin, dass ich nicht weiß, wie ich meine von mir entworfenen Objekte anzeigen soll. und ordne es meiner SPS zu, um es auf meinem Server UaExpert sichtbar zu machen. Ich habe mir das Tutorial-Video https://youtu.be/aJhzN3Uk-Do?feature=shared angesehen. Aber es zeigt Ihnen nur, wie Sie das Informationsmodell hinzufügen, und mein resultierendes Modell hat keinen Informationstyp. Wie kann ich also in Codesys ein Modell anzeigen, das ich in SiOME entworfen und meine Instanzen (Objekte, Variablen oder Methoden) meinen Variablen in der SPS zugeordnet habe? Ich habe Leute gesehen, die es in Tia Portal oder einer anderen Software gemacht haben, aber ich habe keine Ahnung, wie man es auf CODESYS macht

Post by sigurdrb on OPC server in "Communication manager" ^{CODESYS Forge talk (Post)}
Hi! I was thinking of switching the OPC server config from "Symbol Configuration" to the "Communication manager" in the device tree. I Have a lot of arrays of structs that I have previously declared in the "Persistent Variable" object in the device tree. It seems as it is not supported to directly expose persistant variables to the OPC server like the "older" way of doing it in the symbol config. Is this correct? Do you recommend to just do it the old fashioned way, or should I edit the structure of the global variable list / persistant data / OPC server and set up the OPC server from the "Communication manager" object?

Hello Jusito, Can you share your final code, please ? I tried to implement a similar feature (going online, doing the reset and the start). But I get a timeout on the reset/start when I'm testing the script. If you got something working, I would appreciate to see it.

Hello at all I'd like to know how to configure CODESYSControl_User.cfg in order to use a specific network card for OPCUA Server. In the past, I tried to ask in "Forge" about this topic, but I could find neither help nor document informations about it. Reading the file "codesyscontrol.log" I see these logs OPC UA Server Started: Hostname: NTLRPICTRL01, Port: 4840 URL: opc.tcp://NTLRPICTRL01:4840 Loopbackadapter activated. **All available networkadapters are used.** Multithreading activated. 3 workers used. My controller, which is a Linux PC, has got two network cards eth0 and eth1 I whant to use the card with name "eth0" as a server for OPCUA and keep the "eth1" free for other stuffs. Is it possible ? Best regards Rossano

Post by sachem on Problem retain values Weidmuller UC20-WL2000 ^{CODESYS Forge talk (Post)}
Good afternoon. I am working with a weidmuller uc20-wl2000 controller, using a codesys license. We made a ladder code to control a process, and it works well, but we want some variables to remain stored even when the controller is turned off. We tried to use retain variables, but at the time of loading the program, when we went offline from the controller, the program was deleted, it did not remain in the controller, and in the same way if we turned off the controller. In addition to this, when we tried to program it again, the program would not stay loaded and began to present errors with the opc-ua communication. What could be causing this problem? How can we maintain the values of the variables without damaging the program or affecting the controller? thank you

Does anybody know how to get a specific text from a text list within a program. Obviously it works in a visualization, but because I will have an HMI that has it's own system and I will have to send variables to this HMI via an OPC UA connection, I need to be able to get a text into a string. I tried using the VisuElems like this, but it only returns an empty "" and nothing else. IF trig THEN sText := VisuElems.cmpDynamictext.DynamicTextGetDefaultText(ADR(sTextList), ADR(sAlarmID))^; //sText := VisuElems.cmpDynamictext.DynamicTextGetText(ADR(sTextList), ADR(sAlarmID))^; trig := FALSE; END_IF Any help and idea is highly appreciated because I am getting desperate here.

I need to know how i can change the directory of my instances 'inst_3' and so on. So they can be under objects directly. I tried to modify the settings, but couldn't find any leads till now.

Post by alexgooi on Codesys OPC DA server requires more then 2 GB of ram ^{CODESYS Forge talk (Post)}
Dear Forum, We are currently running into a problem that the CODESYS OPC DA server is running out of RAM (larger than 2 GB). We have a setup of 10 Codesys controllers which features around 300.000 discoverable tags per controller. We are only interested in 10 percent of the tags to be communicated to the OPC-server, this is due to the fact the program consists of arrays of objects which on their part implements arrays of objects, simply reducing the number of discoverable tags is not an option The OPC-DA server loads all the discoverable tags, is it possible to: 1 let the OPC-DA server only load the tags that are requested by the SCADA/MES system. 2 let the OPC-DA server claim more memory. 3 run 2 OPC-DA servers in parallel? Thank you in advance
