Hi all, I am new to Github , but not to coding and networks.
However I am struggling for a solution to what appears in the outset, to be a very simple task.
I have a Solis hybrid Solar PV inverter which has a remotely mounted current transfomer (CT) transmission unit that speaks modbus over RS485 back to the inverter. The inverter ( master ) is sending a request for 30 x 16 bit registers from address 31000 to 31029. The CT unit ( slave) replies with the data which includes 31013 which the the only piece of the data ( power exported ) I need.
So my question is :- Can the arduino be configured to’ listen’ for the response from the slave, identify register 31013 and make that data availble ??
I cannot make my arduino a master , as only one master is allowed per RS485 network. Similarly, I can’t make it a slave, as it needs to gather data rather than send it. So … is there a listen / monitor mode. ??
Any thoughts or example code are very welcome.
