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 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

Post by bryandimino on OPC Da Server Code Meter Issues after Enabling License ^{CODESYS Forge talk (Post)}
I'm trying to get the OPC server setup on my machine and currently I'm not having luck. I went ahead and got my license setup. However when I go to run WinCoDeSysOPC.exe I get an error message that I don't have the code meter licenses installed. Does anyone have any ideas on how I can fix this issue?

Post by ofey on two different OPC clients with different privileges ^{CODESYS Forge talk (Post)}
Hi! I have usually only connected one OPC client (our system) to an OPC server created in the codesys environment on a PLC. This OPC client has a lot of write privileges. A customer also want OPC access, but I want to restrict his access to only read certain values. Do you know if this is possible inside the single codesys runtime running on a controller?

it is mandatory to activate the OPC DA license into the 32-xxxxxx legacy container (not UFC) you need a remove ticket -> contact CODESYS store - my question to move the license

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

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
