Post by dennisyhli on Ethernet IP Connection timeout ^{CODESYS Forge talk (Post)}
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?

Most likely your IP address is set to 172.... because you use a VPN connection to your device. Probably best to use the other Ethernet interface for your modbus communication.

One thing you could do is create an object with the variable as field with a function and procedure to get the variable (read) and set the variable (write). These are then called from your program and the vizualization.

Resolved this. There is a config file called CodesysControl_User that I had to edit to set the driver to component 5. I deleted the semi colon next to Component.5=CmpEt1000Drv

Another way to resolve this is to set Codesys to use a specific version of the offending library under Placeholders in the Library Manager.

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.

Hello Julian, could you please check in Chrome Password Manager Settings if the option "Offer to save passwords" is set? With this option selected, a pop-up message will then show up asking whether or not to save the password. Choose OK. Hope this helps.
