Perancangan Trainer Berbasis Programmable Logic Controller (PLC) Dan Human Machine Interface (HMI) Untuk Sistem Kontrol Single Acting Pneumatic Cylinder
INTISARI
Telah direalisasikan sebuah project berupa Trainer PLC Mitsubishi FX3G-60MR/ES dan HMI Mitsubishi GS21 yang digunakan untuk training pegawai baru PT. Global Indonesia, Cikarang. Trainer ini dapat digunakan untuk beberapa fungsi kontrol diantaranya kontrol lampu menggunakan pilot lamp (Running Led), kontrol silinder pneumatic single acting, serta kontrol motor 3 phasa. Komponen kontrolnya terdiri dari beberapa sensor dan perangkat masukan, diantaranya melalui : push button, HMI, barcode scanner, sensor reed switch untuk mendeteksi magnet silinder, dan sensor rotary encoder untuk mendeteksi rpm motor 3 phasa. Sebagai sistem keamannya terdapat mode emergency, dimana mode tersebut digunakan saat terjadi hal tak normal dari sistem. Sebagai perintah untuk mode emergency menggunakan tombol emergency stop. Dalam pengoperasiannya, trainer ini dapat di-setting sesuai dengan kehendak pemakai dan dengan mengikuti manual book yang berisi instruksi alamat dan wiring. Dalam pengoperasian trainer ini menggunakan dua mode, yaitu manual dan otomatis untuk ketiga jenis kontrolnya. Hasil kontrol dapat dilihat melalui dua mode. Pertama, dengan melihat pergerakan mekanis aktuator secara langsung. Sedangkan yang kedua, dengan melihat display kontrol pada human machine interface. Display tersebut berupa indikator lampu, cycle time system, counter, dan monitoring motor 3 phasa.

ABSTRACT
Has been realized a project in the form of Mitsubishi FX3G-60MR/ES and GT21 Mitsubishi HMI Trainer PLC used for training new employees of PT. Global Mega Indonesia, Cikarang. This trainer can be used for some control functions such as lamp contrast using pilot lamp (Running Led), pneumatic single acting cylinder control, and 3 phase motor control. The control component consists of several sensors and input devices, including through: push button, HMI, barcode scanner, reed switch sensor to detect cylinder magnet, and rotary encoder sensor to detect 3 phase motor rpm. As a security system there is an emergency mode, where the mode is used when things are not normal from the system. As a command for emergency mode use the emergency stop button. In operation, this trainer can be set in accordance with the will of the user and by following the manual book that contains instructions address and wiring. In the operation of this trainer uses two modes, namely manual and automatic for all three types of control. Control results can be viewed through two modes. First, by seeing the mechanical movements of the actuator directly. While the second, by looking at the control display on the human machine interface. Display is a light indicator, cycle time system, counter, and 3 phase motor monitoring.
