Description: ModbusSlaveIOException(cause=ModbusIOException, EOF=false, message='I/O exception: IOException CRC Error in received frame: 19 bytes: 01 03 10 11 b5 04 71 10 df 03 9a 00 00 00 00 00 00 00 00 ', cause2=null). Here some additional log reading out specific registersġ3:03:08.784 - Thing 'modbus:data:slave100:slave104holding:Pv_1_Current' changed from OFFLINE (COMMUNICATION_ERROR): Error (ModbusSlaveIOExceptionImpl) with read. Here the configuration of the modus slave in openhab
Running both at the same time i do get CRC errors or even empty responses on the serial modbus O exception: IOException CRC Error in received frame: 0 bytes: ġ2:35:59.226 - Try 2 out of 3 failed when executing request (ModbusReadRequestBlueprint [slaveId=1, functionCode=READ_MULTIP
Error was I/O error, so reseting the connection. Here are some example logs of the modus serial data polls from my openhab:Ģ:35:59.062 - Try 1 out of 3 failed when executing request (ModbusReadRequestBlueprint [slaveId=1, functionCode=READ_MULTIP See attached the screenshot of my product trend graph. Running both at the same time i do get CRC errors on the serial modbusĪnd also have glitches in the fusion portal. I just got an update on my inverter V100R001C00SPC133 and wifi dongle V100R001C00SPC118 In parallel my installer can still access the inverter with the fusionsolar portal. So i use y FTDI USB-RS485-WE-1800-BT to connect to my inverter and read out the data. In openhab the data coming from the inverter can be integrated by means of modbus. Have myHuawei SUNKTL-M1 running for a whiole now and I am also a user of openhab automation.
