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.

Post by arundara on Variable Sync Issue In Soft Plc Redundancy
CODESYS Forge
talk
(Post)
Hello, I was trying to create a redundancy POC for our application where we read data from few modbus tcp devices. As there is a limitaion that modbus tcp device support only for single master device, we wanted to test how the variable sync happens in redundancy mode. For that i have used the redundancy sample code added a variable "b" under a condition. What i observed was while active controller is running, if passive controller is powerup, passive controller is able to sync all the data configured for redundacny. But after that the variable data which resided under a condition is not synching from active to passive controller. I have attached the image where i have highlighter the variable. Can some help me to understand how redundacny work in codesys soft plc and if there is a solution to sync variable which are under condition, please explain the same or suggestion to achieve the same. Hardware - Raspberry Pi (2 qty) Redundancy licence used - yes in both controllers. Codesys runtime - 4.9.0.0 Codesys software version - V3.5 SP19 if i have posted this question in wrong section, please do let me know in whcih section i have to post this question.

Hallo zusammen, ich hab ein kleines Problem bei einer Modbus TCP-Verbindung von meinem RaspberryPi (ML) zu einem Fronius Wechselrichter. Ich habe mir die CodeSys Version 3.5SP20 heruntergeladen und die Runtime auf dem RaspberryPi mit aktualisiert. Gerät ist ein Fronius Symo 6.0-3-M Folgende Konfiguration habe ich im Wechselrichter (Siehe Bilder). Laut Registertabelle fangen die Daten bei Adresse 40001 an und gehen im Modus int+SF bis 40120 Ich habe mir also im Ethernet-Adapter einen Modubus Master und darunter einen ModbusSlave angelegt. Der Slave (Fronius) hat bei mir die IP 192.168.2.46 dazu UnitID und Port. Ich habe dann einen Kanal mit den 120 WORDS und dem OFFSET angelegt. Wenn ich nun die Konfiguration übertrage , scheint erst mal alles zu passen.. aber es flackert immer wieder ein Fehler beim Slave auf (kann nicht erkennen welcher und finde auch keine Diagnose). Es werden auch keine Daten übertragen. Alles bleibt auf 0. Ich muss dazu sagen, dass ich noch eine weiter Modbus TCP Verbindung zu einer anderen SPS habe. Die funktioniert wunderbar. Normalerweise sollten ja auch mehrere Verbindungen gleichzeitig möglich sein oder? Wäre top, wenn ihr mir helfen könntet, den Fehler zu finden. LG Chris

Post by gilbert-mh on CAA net base TCP client cause PLC to crash - Kernel message : N0HZ_local_softirq_pending 80

Hello all, I have been trying to implement a TCP client on a Festo PLC (CPX-E-CEC-M1) and it looks like it works well except that after some time (greatly varies between a few hours to more than 100h) my PLC crash. When I look into the log file the only thing I see is that before the crash happens a few kernel warnings : N0HZ_local_softirq_pending 80 and then the crash. I've looked into this warning and from what I could find on the net it seems that this is warning is triggered when the ethernet link is down. I've tried to correct this bug for quite some time and what I know is that : - The crash is caused by my TCP client, when I remove it from my code I see no crash - The crash happens more quickly the more the TCP client is used. - The time before the crash is not directly proportional to the number of communications or their size. But it looks like it is just more likely to happen if the client connect to the server at a higher frequency. - The precedent observation makes it seem unlikely that the crash is caused by some memory overflow because then the crash speed would be more proportional to the amount of data exchanged. SO from these observations, I believe that the crash could be caused by the PLC trying to connect to a server while there is some kind of issue with the ethernet link resulting in the PLC getting stuck in some indefinite state and making it crash. This still seems a bit unlikely to me because if the ethernet is down it simply shouldn't be able to contact the server and the communication would just fail which doesn't cause my PLC to crash. Has anyone encountered the same kind of problem (with the same kernel message) ? I am pretty sure the warning is not the direct cause of the crash but just an indicator that something is wrong with my PLC. Thanks in advance

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?

ah ok, I will keep trying, I already removed all security from the Server side. I'm new on codesys and I don't know yet how to implement the certificates, but I will find out and also try. thanks for your reply.
