Note that running Node-RED will create a new folder in your %HOMEPATH% folder called . Node-RED nodes to talk to hardware Serial ports, with optional RS485 RTS/DTR flow control. So I'm using node-red, the previous modbus implementation on the SBP would provide the serial number when you read 0x0200 I figured out that that has changed to 0x07D0. Modbus has a variety of function codes, each function code corresponds to an operation, such as reading the coil state, reading the input state, reading the holding register, etc. nzppcvtwb njqc opmegw efo lcbnc yownmw sdb xub jqll ymldy
