jika sudah selesai upload dan merangkai silahkan di uji

download dulu software modscan

tancapkan usb to rs485 to pc or laptop

run modscan

connection -> connect

pilih connect using : sesuaikan port usb nancap dimana

baudrate 9600
worklenghr 8
parity none
stopbit 1
klik ok

lenght ganti 3
coil status ganti holding register

jika valid response sudah ada angkanya berarti anda sudah berhasil

rangkaian dari upload file modbus

upload sketch modbus RTU RS485
