Post by joel214 on OPC-UA / Unterschied Symbolkonfiguration, IEC-Symbolveröffentlichung und Informationsmodell ^{CODESYS Forge talk (Post)}
Hallo liebe Community, im Rahmen einer Studienarbeit gilt es ein OPC-UA-Informationsmodell in eine existierende CODESYS-Steuerung zu implementieren. Dabei sind wir auf die Frage gestoßen welcher Unterschied zwischen den folgenden Objekten besteht: - Symbolkonfiguration (veraltet?) - IEC-Symbolveröffentlichung - Veröffentlichung über zuvor erstelltes Informationsmodell In unserem Verständnis erfüllen alle Objekte die Gleiche Aufgabe nur mit unterschiedlicher Vorgehensweise und Darstellung im OPC-UA-Server. Während durch die Symbolkonfiguration die Variablen und Instanzen über lange und verschachtelte Pfade abgelegt werden, wird durch die IEC-Symbolveröffentlichung ein Ordner im Pfad der Objekte erstellt. Dort sind die Variablen und Instanzen anschließend zu finden. Bei der Verwendung von Informationsmodellen hingegen, werden die Instanzen direkt unter den Objekten abgelegt. Für welchen Anwendungsfall ist welche Vorgehensweise am besten? Vielen Dank vorab und viele Grüße Joel

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

Post by khaledkhalil on Import OPC UA model to Codesys ^{CODESYS Forge talk (Post)}
I have added a models in SiOME which a software to design nodes and add instances. and created a resultant xml file. I tried to import the xml file to Codesys through OPC UA information model Repository the problem i don't know how to view my objects which i have designed. and map it to my PLC to make viewable on my server UaExpert. I watched the tutorial video https://youtu.be/aJhzN3Uk-Do?feature=shared. But it only give you how to add the Information model, and my resultant model doesn't have information type. So how in Codesys i can view a model which i have designed in SiOME and mapped my instances (Objects, Variable or methods) with my Variables in PLC I saw people do it in Tia Portal or other Software, but i have no clue how to do it on CODESYS

Post by alexgooi on OPC-UA and other communication questions ^{CODESYS Forge talk (Post)}
Dear forum, I currently have a big question mark above my head, and maybe this forum can shine some light on the situation. I recently updated to Codesys 3.15 SP19 Patch 6. And now I’m trying to setup the OPC-UA server, besides that I’m trying to connect to the controller with the Codesys V3 (Ethernet) protocol. OPC-UA I have installed the correct licenses on my controller (Runtime and communication). I’m able to connect to the controller with an OPC-UA client, and I’m able to browse the tags, so far so good. Therefore I’m assuming that the OPC-UA server is running on the controller. But now the strange part, in the device security settings I have set the communication Policy to BASCI256SHA256 ( I also have tried the other ones) and the communication mode is set to secure if possible (I also have tried all the other ones) (see picture). With these settings I would assume that I would only be able to login with a Basic256SHA256 policy with a client. But the opposite is true, I am able to login using the no policy mode and when I set it to Basic256SHA256 the client (UA-Expert) notes that this policy is not available on the server. I then check the certificates and I noted that there is no certificate for the OPC-UA server, I tried to generate one but it gave the error that the certificate has not been created by the device (See picture). To summarize I have no clue what is going on, and the controller does the opposite of what I would expect. Codesys Ethernet V3 driver I have a HMI connected to the same controller using the Ethernet V3 driver. But this will not connect. I tried all the Protocols (see picture), with and without the username and password enabled. But it will not connect, when I scan the available servers I can see the controller with the port number that I am expecting, so I’m assuming that the Codesys V3 ethernet driver is up on the controller. Does anyone can give me some direction, because the stuff that I tried doesn’t make sense to me. Thank you in advance

Post by dsa28 on OPC UA subscriber not operational ^{CODESYS Forge talk (Post)}
Hello All, Hopefully I can get some help configuring an OPC UA subscriber in a CODESYS runtime in a Raspberry Pi 5 that tries to retrieve data from an OPC UA publisher (in this case running in a TwinCAT system). I tried to follow the steps described in the page to implement the OPC UA subscriber: https://content.helpme-codesys.com/en/CODESYS%20Examples/_ex_opcua_pubsub.html Seems that the example provided was created with version 3.5.16.0. Now with version 3.5.20.20 is not possible to open the complete project neither convert it. Anyway, after configuring all IPs and ports used in the OPC UA connection function block but the connection state always shows DISABLED. Can someone help me to do the proper configuration of the OPC UA subscriber? Many thanks in advance.

Post by dogulas on OPC UA C# client connecting to OPC UA CODESYS server ^{CODESYS Forge talk (Post)}
Noob alert! I’m just getting my feet wet with CODESYS. I have a “Hello World” project in the CODESYS IDE. I’m using the Win SoftPLC on the same computer. I’ve added a Communication Manager under the Application node. Under that is “OPC UA Server -> IEC Symbol Publishing 01”. I also added “OPC_UA_Symbols -> Information Model”. I’m not sure I need the second thing. I was grasping at straws. I also set up several dummy symbols in the IEC Symbol Publishing 01 node. In my C# application, I am trying to get an instance of EndpointDescription from CoreClientUtils.SelectEndpoint(“opc.tcp://localhost:1217/Gateway-1”, useSecurity: false, 15000). I wasn’t sure about the “Gateway-1”. I found that in the CODESYS IDE under the project -> Communication Settings. When I execute the previous method call in C#, I get: “BadSecureChannelClosed”. I have no idea what that means. Any pointers to documentation are welcome.

Post by tcarlbom on Read tag values using external program ^{CODESYS Forge talk (Post)}
This is my first time posting in this forum and I am new to codesys. I am a fullstack developer and I am trying to figure out how the following. What would be the best approach to create a own/custom tag browser? Either directly in codesys ide or using a separate custom program (perhaps a winforms application). 1.a. Shall I parse the .project xml file to get a list of all tags in the project? 1b. Shall I use python scripting in codesys ide to get a list of tags? Once one have selected some tags. These tags shall be exposed to a python program which will be acting as a edge computer. It’s fine to be able to import a file. 2a. I found a library called codesys plchandler which (as I understand) acts a rest api server. Is this correct? If so, can I query the api from a custom python script, ie can query what tags exist in project and or read tag values? My research so far. From earlier projects I know that using opc ua would be perfect for this but from my opinion it’s bloating the plc since it’s resource intensive. So opc ua is not an option. Codesys automation server is neat. But I don’t want to rely on some cloud services and subscription based pricing. There seem to be several interesting codesys libraries like mqtt, tcp server and NVL sender which would help me expose plc tags. But all have a common problem. One have to manually write what tags which will be used in these function blocks. I want a similar experience like “selecting” tags in the opc ua or the codesys tracing, ie a tag browser.

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

Perfekt, das war es. Node ist zu sehen. Es hat mich schon etwas gewundert, dass die Zertifikatverwaltung zwischen Codesys und WBM auseinander lief. D.h. der OPCUA Server, den man im WBM konfigurieren kann, ist (in diesem Fall mit einem 750-8202) der WAGO OPCUA-Server?
