Tutorial merakit RTU Modbus TCP Arduino
1. Masukkan
library Mudbus ke folder C:\Program Files\Arduino\libraries
2. Run
Software Arduino, bisa download disini https://www.arduino.cc/en/Main/Software
3. Masukin
sketch

//Function codes 1(read coils), 3(read registers), 5(write
coil), 6(write register)

4. Tancapkan kabel
data ke arduino dan port usb laptop/PC
5. Klik Verify untuk Compile sketch
yang dicopy tadi,
6. Setting board
dan port arduino
- Pilih Tool – board – arduino uno
-
-
Pilih Tool – Port- com (sesuai arduino, cek di device
manager)
7. Upload Sketch ke arduino
8. Settiing IP
laptop/PC 192.168.1.87(87 bisa di ganti angka lain selain 10(ip RTU) dan 1(ip
gateway))
9. Tancapkan Ethernet
shield to arduino
10. Tancapkan kabel
UTP to port RJ45 ethernet shield dan port RJ45 laptop
11. Cek komunikasi
RTU menggunakan Command Promt (CMD)
-
Ketik perintah : Ping 192.168.1.10 untuk cek sesaat
-
Ketik perintah : ping 192.168.1.10 –t untuk
cek seterusnya
12. Test RTU
menggunakan modscan32
13. Setelah
koneksi menggunakan modscan berhasil, itu menandakan RTU Modbus TCP arduino
sudah sukses.
klik mudbus untuk tahap selanjutnya
