1. Wiring

Datalogger

ke Mesin

Berikut ini adalah gambar

wiring

diagram pemasangan

datalogger

ke mesin

forming

PT Kepuh Kencana Arum.

Gambar 1.

Wiring

datalogger ke mesin

Gambar 1 diatas merupakan

wiring

atau pengkabelan dari datalogger ke mesin

produksi sehingga arduino dapat membaca mesin secara keseluruhan, mulai dari

pembacaan

rotary encoder

, mode manual otomatis, dan juga dapat mengetahui mesin

forming

tersebut dalam keadaan hidup atau mati.

2. Langkah Instalasi Alat

Langkah-langkah yang harus diperhatikan saat memasang datalogger ke mesin

forming

adalah sebagai berikut:

1. Testing

mesin untuk mengetahui pin pada

wiring

PLC yang digunakan untuk

tombol FOR pada mesin dan sensor potong mesin.

2. Matikan mesin, pastikan mesin dalam keadaan mati.

3. Upload code arduino, pastikan waktu sudah tepat dan code berjalan sesuai

dengan proses mesin.

4. Upload code nodemcu dan pastikan wi-fi dapat terhubung dengan nodemcu.

5. Sambungkan kabel dari datalogger ke mesin sesuai dengan gambar 1 diatas.

6. Hidupkan datalogger, kemudian jangan lupa colokkan adaptor.

3. Koding Arduino
