Dari panel tampilan ke PLC, sinyal yang dikirimkan adalah sinyal arus listrik. Sedangkan dari meter utama ke panel tampilan, sepertinya bukan sinyal arus listrik

Ada berbagai macam sinyal, seperti tegangan, arus, dan resistansi

Umumnya bukan sinyal arus listrik, yang saya temui kebanyakan adalah 232. Ada juga yang menggunakan 485.
