Saran - KESIMPULAN DAN SARAN - TUGAS AKHIR - Konsol virtual sebagai pemrogram PLC mikrokontrole

BAB V KESIMPULAN DAN SARAN

5.2. Saran

Konsol Virtual masih dapat dikembangkan dengan menambahkan fungsi-fungsi pemrograman PLC yang lain. Sebagai contoh yaitu penambahan fungsi-fungsi penyusunan program dengan gambar dalam bentuk ladder diagram tanpa harus memahami bahasa mnemonic terlebih dahulu.

Penambahan fungsi komunikasi juga masih dapat dikembangkan seperti penambahan fitur pemilihan port komunikasi atau penggantian jalur komunikasi dengan port USB (Universal Serial Bus) sesuai dengan perkembangan teknologi komunikasi yang ada sekarang ini.
