I am reading values from PLC (modbus/tcp) which has analog sensor using modbus node red, and I used input anolog register and read one register. it returns values such as [ 9088]. and it works switch on/off LED when the temperature goes up . I read this value through node-red modbus but I cannot write on LED. I sent zero or one to the coil but it doesn't work and I can't read the values using node-red from coil. I am using the same address for slave (100), and I am not sure if it has different address. could you help me to figure out the problem?
