The sensor manual is shared above. I want to communicate with it through Modbus RTU node. My code is given below:
[{"id":"5f61c311.3e5d1c","type":"tab","label":"Flow 1","disabled":false,"info":""},{"id":"b3e619e4.41ca08","type":"modbus-read","z":"5f61c311.3e5d1c","name":"","topic":"","showStatusActivities":true,"logIOActivities":false,"showErrors":true,"unitid":"1","dataType":"InputRegister","adr":"1","quantity":"1","rate":"30","rateUnit":"s","delayOnStart":false,"startDelayTime":"","server":"1c521864.046078","useIOFile":false,"ioFile":"","useIOForPayload":false,"emptyMsgOnFail":false,"x":340,"y":140,"wires":[["94edf5aa.8613a8"],["3bf738d0.3f1648"]]},{"id":"3bf738d0.3f1648","type":"debug","z":"5f61c311.3e5d1c","name":"","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"payload","targetType":"msg","x":750,"y":140,"wires":[]},{"id":"94edf5aa.8613a8","type":"modbus-response","z":"5f61c311.3e5d1c","name":"","registerShowMax":"10","x":660,"y":40,"wires":[]},{"id":"1c521864.046078","type":"modbus-client","z":"","name":"","clienttype":"simpleser","bufferCommands":true,"stateLogEnabled":true,"queueLogEnabled":false,"tcpHost":"127.0.0.1","tcpPort":"502","tcpType":"DEFAULT","serialPort":"/dev/ttyUSB0","serialType":"RTU","serialBaudrate":"9600","serialDatabits":"8","serialStopbits":"1","serialParity":"none","serialConnectionDelay":"100","unit_id":"1","commandDelay":"1","clientTimeout":"1000","reconnectOnTimeout":false,"reconnectTimeout":"2000","parallelUnitIdsAllowed":true}]
I am getting error message which says: Error: Data length error, expected 7 got 2
Please help me out!!
