I use ethernet ip scanner and the connection type is set to multicast. After running the PLC, the ethernet IP will have a connection timeout every 10 seconds. What is the reason for this error?

Post by egau on Hard shutdown: no code on device after power on ^{CODESYS Forge talk (Post)}
Hi, We have a machine running Codesys on a Windows IPC (CODESYS Control Win v3 - x64). When we hard shutdown the machine, the code on the PLC sometimes becomes "corrupted" after a power on (When trying to login to the PLC, we get the message "The application 'Application' does not exist on device."). I've noticed these errors in the logs, but I'm not sure what to make of them. We are not using any RETAIN variables in our code, although I'm not sure about referenced librairies. (we are using the persistence manager). I'm pretty sure that not doing a graceful shutdown is the root cause of this. This being said, what is the proper way of doing a graceful shutdown? Is putting the Codesys application in "stop" sufficient? I know how to implement this, so if it works then it would be a quick fix. However, I think we need to add a UPS, which would detect power loss and inform the PLC that it needs to initiate its shutdown, and then the PLC would shutdown gracefully. Any help with this will be greatly appreciated :)

Is there any way to have EoE working with Tap names different from tap0? My PLC manufacturer uses Tap0 for the remote assistance service and it's not avvailable for other uses.

Suddenly CODESYS gateway has been stopped running as below picture so I’m not able to scan network PLC. I also tried to start CODESYS gateway service manually but its giving error as below. Have you faced this kind of problem before ??

Hi, Yes this should be possible, you should find the CodesysControl.cfg file on your plc. Open this with a text editor, and change the placeholder filepath for alarms. You can find the Placeholder filepath in the CodesysControl file under Sysfile.

Post by gilbert-mh on CAA net base TCP client cause PLC to crash - Kernel message : N0HZ_local_softirq_pending 80 ^{CODESYS Forge talk (Post)}
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

Post by dhumphries on How to determine code size ^{CODESYS Forge talk (Post)}
I'm trying to determine which Codesys Control license I need, the Control Standard S has all the features I think I'll need, but the code size is limited to 3mb, I created a simple program with only 1 line of ladder logic and a simple visualization with a button and an indicator. When I generate code I get some messages, one indicates that the total allocated memory size for code and data is 2.1mb. Is this metric the correct size of the code? I question the size because it exceeds the allowable code size for the Basic S and Basic M licenses and consumes 2/3 of the available memory for the Basic L or Standard S license. What tool can I use to estimate the size of code as it relates to the runtime license limit?

Post by timl on Application has invalid license metrics ^{CODESYS Forge talk (Post)}
Hallo, ich habe eine Control for Linux SL auf der ich einen TCP Modbus Master anlege, mit dem ich einen Slave auslesen möchte. Das Anlegen funktioniert soweit alles, sobald ich beim ModbusTCPSlaveE/A-Abbild in den Channel eine Variable einfüge, damit ich den Channel auslesen kann, kommt es beim übertragen auf die SPS zu einem Ausnahmefehler. Im Anhang noch eine Bilder der Fehlermeldung und der installierten Lizenzen. CODESYS Version ist V3.5 SP19 Patch 4 Meinem Verständnis nach ist die Modbus Lizenz mit in der Control Standard L inbegriffen und auch in der Lizensierten Softwaremetrik sehe ich keine überschreitung meiner Lizenzbegrenzungen. Daher verstehe ich nicht wieso ich diesen Fehler bekomme und eine auslesung via Modbus nicht möglich ist. Gruß Tim
