Okay, the solution was so simple... In my case, you first have to add the EL1918 and then the EL2904... then the connection is made automatically. I probably had something else before and then added the EL1918... then it doesn't catch the connection :/

Post by ahuckphin on Issues with Modbus Slave with Raspberry Pi ^{CODESYS Forge talk (Post)}
I have a DFRobot RS485 temperature & humidity sensor (SEN0438) connected to my Raspberry Pi via a USB to RS485 adapter. I am able to connect and read the sensor data when running a python code locally. However in Codesys, I encounter this error "A bus error has occurred." and "There was no response in time". Could this be because of Modbus Server Channel and Modbus Server Init configuration on my part? Admittedly I am new to Codesys. To get to this stage, I: 1. added some lines to CODESYSControl_User.cfg 2. added "Modbus_COM" in Codesys and set "Serial Port Configuration" under "General" 3. added "Modbus_Master_COM_Port" in Codesys and checked transmission mode is set to "RTU" 4. added "Modbus_Slave_COM_Port" in Codesys and checked server address is set to 1 (also set 1 in my sensor) 5. added 1 channel and 1 init for "Modbus_Slave_COM_Port" under "Modbus Server Channel" and "Modbus Server Init"

is your pointer set to the correct visu client? set a breakpoint in your client iteration and step through the active visu clients like programming system, targetvisu, webvisu,... and check the last usage value of each client

Thanks for your answers! Close and Open CoDeSys has no effect. I already tried the original Roboto and this is working. But I think our marketing compartment changed it.

Is it really the same CODESYS version with the same add-ons? Maybe open the CODESYS installer on your home laptop, and export the configuration. On your work PC open the CODESYS installer and import the configuration.
