I've managed to run Ladder logic code on a virtual PLC running on my laptop. Now, I want to connect to a device over EthernetIP, but I always get the "No driver found" message. Can anyone shed me some light?

Hello, is there a possibility to change modbus server parameters (baud rate, parity, etc.) configured in devices tree from PRG? I need to be able to change them, for example, from HMI.

It would be such a simple fix to first check if the file is missing or changed before writing to it, onedrive only has a problem because codesys writes to the file every second no matter the change.

Post by mainak on OPC UA C# client connecting to OPC UA CODESYS server CODESYS Forge talk (Post)
it could be due to security settings. In codesys IDE, go to device-> change run-time security policy, and click the checkbox that says "Allow anonymous login". try if this works.

Does the OPC UA server have a generic username and password? It doesn't seem to be the same as the device username and password.

Post by tk096 on How to get the motor scaling value from code CODESYS Forge talk (Post)
Hi, unfortunately, in Softmotion you have only access to the combined fraction - the scaling factor from user units to motor increments. It can be accessed using MC_ReadParameter with parameter number 1054. increments = user_unit_position * fScaleFactor

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.
