Post by peterned on Programatically restart Codesys OPC UA server? ^{CODESYS Forge talk (Post)}
Hi, I'm using a Festo Codesys PLC (CPX-CEC-C1-V3), which is connected to a HMI panel. Both exchange data via OPC UA. Occasionally, the HMI stops displaying data, and looks as if there is no connection. If the HMI stops, the only way to make it work again is to restart the PLC. Restarting HMI has no effect. When the PLC is restarted, HMI starts working normally again. Is it possible to restart the OPC UA server from PLC code? I hope this will make fixing the HMI possible without a PLC restart. Thanks

Post by alimans on OPC-UA Server, Symbol Set: Raise an error: Object reference not set to an instance of an object. ^{CODESYS Forge talk (Post)}
Hi everyone, I just created a very simple library without any code and, added it to my very simple project. after adding this library, I get an error when I try to open "Symbol Set" in "OPC UA Server" in "Communication Manager". Here is the code of my POU in the library: FUNCTION_BLOCK POU VAR eCommand : (CMD_NONE:=0, CMD_RESET:=-1) INT := CMD_NONE; END_VAR Attached is the error that I get. I also noticed that by removing the enumeration variable above (eCommand), I can open the "Symbol Set" again. Anybody has any idea why this error is raised and how could I use enumeration variables without error in "OPC UA Symbol Set"?

Post by wiekon on OPC UA Probleme ^{CODESYS Forge talk (Post)}
Hallo zusammen, ich hoffe, ihr könnt mir helfen. Eigentlich möchte ich etwas ganz einfaches erreichen: CODESYS Runtime auf Raspberry Pi (OPC UA Client über Datasources Manager) <--> Cognex Designer (OPC UA Server) auf Windows PC Es will einfach nicht klappen. Wenn ich die Datenquelle hinzufüge, Adresse opc.tcp://192.168.150.10:4840 kommt immer BadRequestTimeout. Es ist keine Security und keine Authentication auf dem Server eingerichtet. Auf dem gleichen Raspberry klappt es aber wunderbar mit dem Tool opcua-client! Das heißt für micht, es ist kein Raspberry oder Firewall Thema. Was auch geht: Diese CODESYS Runtime auf dem Raspberry ist OPC UA Server (einfach über die Symbolkonfiguration) und eine andere CODESYS Runtime (ControlWin auf meinem Rechner) ist Client und verbindet sich über den DatasourceManager. Allerdings: Die Daten kommen im Client nur im 1s Takt an, obwohl die Aktualisierungsrate auf 10 ms eingstellt ist und sowohl Server, als auch die DatasourcesTask im Client auf 10 ms laufen. Ich kann einstellen, was ich will, es bleibt bei exakt 1 Sekunde Aktualisierungszeit im Client. Warum ist das so? Wenn ich auf dem gleichen Windows PC, auf dem die ControlWin läuft den UaExpert verwende und mich zum Raspberry verbinde, kriege ich die Daten im 10 ms Raster! Am Server liegts also nicht! Zurück zu meiner eigentlichen Aufgabe: Ich konnte mir vorübergehend so behelfen, dass ich auf dem gleichen Raspberry einen IO-Broker laufen lasse, der zwei Instanzen des OPC UA Clients hat. Er verbindet sich mit dem OPC UA Server des Raspberry und des Cognex Designers (also die zweite Instanz auf dem Raspberry, die es schafft, sich mit dem zu verbinden, nur Codesys schafft es nicht). Der IO Broker ist also das Bindeglied zwischen beiden OPC UA Servern. Über Javascript kopiere ich bei Wertänderung die Daten vom einen Server auf den anderen. Das ganze Funktioniert tadellos, nur die Performance ist nicht so toll, wobei ich mir nach der Erfahrung mit den zwei Codesys Instanzen nicht sicher bin, ob es nicht an Codesys liegt und der IO Broker nichts dafür kann. Ich komme mit dem Thema einfach nicht weiter. Könnt ihr mir Tipps geben? Am liebsten wäre mir natürlich der direkte Weg: Cognex Designer als Server --> Codesys als Client Aber zur Not wäre auch der IO Broker ein gangbarer Weg, allerdings muss die Performance stimmen. Gibt es noch weitere Wege? Ich danke euch für eure kreativen Ideen und Lösungsvorschläge!

Hey, I am facing the same problem. Basically UA Expert and other programs work fine with the login credentials. But codesys can not use them properly. I can see the server login to it manually but when I download the program and run the datasource never runs... Currently I am facing the same Error ID: 7012 and cant get it running properly.

Post by yr00 on OPC UA datasource low read frequency ^{CODESYS Forge talk (Post)}
Hello everyone, I am trying to test the OPC UA client feature in Codesys. My setup is the following; I have a Codesys simulation/ visualization running on Control Win V3. My OPC UA server is hosted on a Siemens 1518 PLC using PLCSim Advanced. The setup is completely virtual so there are no really PLCs. Everything is on my laptop. Writing data from the Codesys simualtion to the server is very quick. I have a PLC program running on another 1500 PLC which reads data from simulation via the server, and changes in the simulation (e.g. button pressed) appear within hundreds of miliseconds if not tens of miliseconds in my PLC program. However, when it comes to reading data from the OPC UA Server by Codesys, it taks around 1-2s. I connected a UAExpert client and it gets update very quickly so I am fairly sure the problem is with Codesys. I have tried changing the update rate in datasource -> General and Diagnosis, but it doesn't seem to have an effect. Do you guys have any suggestion on what I can do?

..dann mal im WBM alles deaktivieren, da der OPC UA Server ja direkt im PFC200 SL RUntime integriert ist und nicht über die WBM Oberfläche zu konfigurieren ist.

Same for me. I have problems with UAExpert too. Can't see the Current Value of Enum and can't control. Did some Tests with Python opcua library. Not working with the communication manager so far.

@eschwellinger - We are experiencing the exact same issue. RunTime 3.5.19.70 and IDE V3.5 SP21. It's 100% reproducible. All you have to do is disconnect the network cable for about 10 minutes. OPC UA Crashes and requires a reboot to fix.

Post by thn-power on How to change OPC NodeId IdentifierType ^{CODESYS Forge talk (Post)}
Hi Yet another OPC UA question. When setting up a OPC server using "Communcation manager" (Symbol set and information model) in Codesys the NodeId is always given as "opaque" type. At least when browsing using UAExpert. Other standard OPC objects use numeric (or string) identifier, but for some reason my variables seems to get opaque/binary type. See attached photo. How can I change this? I can't see that this is a parameter in the CodesysControl.cfg. Can this be specified in the information model nodeset? And is it possible to specify the exact numeric or string NodeId for each instance? And on a related topic, is there a way to export the OPC server nodeId's with variable name so that it can be imported in a OPC Client? The .xml files in the project folder does not seem to contain the NodeId.
