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"

Post by shabroz-gill on Exception when OPCUA datasource disconnects from Server ^{CODESYS Forge talk (Post)}
If i loose the network and the opcua data source suddenly looses connection with the server, i get an exception and my application stops working. I am using the latest version of the communication add v4.5.2.0 Is this a known issue? This makes the datasource unusable because it is inevitable that we will loose connectivity at some point, and the datasource crashing everything due to that seems to be a deal breaker. I can provide more details is someone from codesys is reading this. You can recreate is by just shutting off the Opc server after the codesys data source is connected and reading data from it. The codesys app does not crash everytime and sometimes it is able to reconnect without crashing, so you may have to try this a few times to see the exception. Best regards

Maybe the CODESYS HMI is a good solution. https://store.codesys.com/en/codesys-hmi-sl-bundle.html Run this on the remote main control station. In the HMI application you can add the data source manager and to this manager you can add Data sources. A data source has a reference to the PLC you want to connect to and can get access to the variables of the PLC application. You can then use these variables in the visualization of the HMI application.

Post by nha451 on EIP Scanner not receiving data from adapter ^{CODESYS Forge talk (Post)}
Hello, I have an EtherNet IP adapter (GoPxL) running with a virtual PLC. I have successfully connected the adapter with green icons next to it. On WireShark I can see the data coming from GoPxL but on CODESYS it shows up as all 0. My firewall is turned off and I have enabled the device to always update variables. I tested my set up with Profinet and I can receive the data. Please let me know if you have any suggestions!

Hello otdeveloper, I am very interested in this topic. I have been dedicated to IEC 61499 for some time and I would like to understand if the time has come to adopt it in the real world of automation or if it will continue to fill up research papers only.
