Post by mejak on Raspberry Pi USB HID RFID Reader - read ID in plc program ^{CODESYS Forge talk (Post)}
Hello, I have an RFID reader that is detected as a keyboard. While looking for information, I came across examples using visualization. I would like to read the ID without visualization or external code in python, only in PLC. I found on the forum that you can try reading directly from potru /dev/... https://forge.codesys.com/forge/talk/Runtime/thread/24b3527036/ How to read values directly in codesys? Or maybe there is another solution? Best Regards

Post by eschwellinger on License problem gateway ^{CODESYS Forge talk (Post)}
I just try to help. Anyway it is a big difference if a Store SL runtime or an oem plc and licence is used. These licenses need to be activated on plc side - so you have dependencies to the version (CODESYS and Runtime Version) Did you ever ask Epis out for this situation? They should know which license fit to their device. Even they should know if the device is capable for Softmotion and see the requiremnts in the CODESYS store: Runtime 4.9.0.0 - how should this work with Epis 3.5.16.x? Anyway refund is not a problem.

Post by winki on Modbus TCP & RTU with Control for Linux SL ^{CODESYS Forge talk (Post)}
For small project, I would like to use my industrial computer as a PLC + Industrial Computer. Like that I can save the cost of one PLC. That why I am using Codesys on Linux. With the nic it is not working. I already set the IP adress with /etc/network/interfaces. Can it comes from there ? looking to "Control Linux SL" docuemntation it should work with rtu.

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?

this is a security issue not to read/write in the plc allowed path I would recommend to update and change the path in the application were the files are😏

Could you please give me an example where to select new path in plc. Right now my csv files are placed into /home/user/csvfiles

Post by eschwellinger on RPI Zero w - Edge gateway cant install ^{CODESYS Forge talk (Post)}
ok now it is clear - this is a single core Pi Zero W. For this device there is no edge device available. But just for working with CODESYS it is not really needed and yes plc runs only for 2h unlicensed.

Hi all, I am also looking for a solution to transfer a csv file from ifm HMI-PLC to some cloud and finally to node-red, for example. Do any of you advise me how to do it? Thanks

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 nathant on Easiest RevPi PLC to configure HMI visualization with? ^{CODESYS Forge talk (Post)}
I'm worried that the Core SE (which I was originally going to go with) will not be straight foward in terms of setting up the HMI visualization. This is for an offline application, if that matters.

Post by eschwellinger on function block output ^{CODESYS Forge talk (Post)}
I think you should use a piece of hardware in between your drive (pulse/direction) and the plc like for example Beckhoff EL2521 - so Ethercat might be to choice if you need CNC and SoftMotion. EK1100 and EL2521

not sure on which plc you are - there might be the option with: https://forge.codesys.com/drv/sm3raspistepper/home/Home/ but it is more or less Pi restricted and need additional hardware too I guess.

Hi there, I am having a similar problem like you. I have 3 screens connected to one PLC. I have set 3 different URLs for them. But 3 of them are still dependent to each other. How can I make them independently ? Kind regards, Jin.

Post by yannickasselin on Connect to remote PLC via local pc and teamviewer ^{CODESYS Forge talk (Post)}
Yes it is possible. I did it a lot of times using TeamViewer VPN. Unfortunately, TeamViewer VPN only works on Windows. If the remote PLC is a Codesys runtime running on Windows, you should be able to login directly using TeamViewer VPN if it is installed on the PC/PLC. If it is not Windows based, you can still do it but you need to have a Windows based PC acting as a gateway in the middle. In this case you need to enable IP Forwarding on the Windows remote PC (the gateway) and you need to setup the gateway IP address on the PLC to be the address of the Windows PC. Then you need to add a route on your local PC to point to the gateway PC for Codesys communication. I know it may not be detailed enough but I did not want to make a whole tutorial on how to do it. Bottom line, it is possible. I do it all the time.

I'm no longer working with this PLC brand, but if I were you, I would try to stop all related Codesys services before the copy and restart them after that.
