I have a script(modbus_script.sh) running in etc/rc.local for now and I’m utilising:
"ubus call modbus_client.app tcp.test {…}.
It was difficult to find examples and documentation.
If Read is ok I will write EXT_VALUES with function 16, to reg_count:“Val1 Val2..” I will upload my findings later.. There ought to be more clearcut examples with writing and reading modbus data from tcp nodes.
Firmware FW: RUT9M_R_00.07.13.3
