Mengoperasikan Programmable Logic Controller (PLC) - Teknik Otomasi Industri

Assalamualaikum warahmatullahi wabarakatuh, greetings of prosperity. In this video we will learn about operating the programmable logic controller, better known as PLC.

The topic we choose today is to operate the VLC to control the working system of two three-phase induction motors with life and death operations in sequence. Later, by using the same concept, of course this system can be applied for systems that are much more complex, such as to control the machines in the industry, to control the lift, conveyor, and so on.

Welcome to watch! Learning Goals Through practical activities, students can operate the Programmable Logic Controller system or PLC to control two three-phase induction motors with life and death operations in sequence independently.

Panel Box USB 2.0 Type B Cable PLC The PLC we use is Omron CP1E N30DRA 24VDC Power Supply 3 Phase Induction Motor 24VDC Magnetic Contactor Thermal Overload Relay

This is

PLC input and output circuit This circuit connects the PLC and the input device used, namely push button and thermal contact of the product. Next, PLC is also connected to the output device, namely the magnetic contactor and the indicator light. Then, the motor circuit is used to connect the three-phase voltage source to the electric motor. The ladder diagram is designed to control the input and output devices.

For this practice, we will use the following diagram. Before doing the practice, do a check on each component that will be used. Check the push button condition using the ohmmeter. Make sure the contacts on the push button work well. Check the terminal using the ohmmeter. Make sure the terminal is in good condition. Check the magnet contactor using the ohmmeter.

Make sure the coil and the contactors work well.

Next, install the components to the panel box. Measure the hole position on the panel cover for the push button placement and the indicator light as shown in the picture. Measure the position of the cable duct, omega rail, and terminal on the inside of the panel.

for the placement of components and installation of wiring. Make a groove on the panel cover according to the size that has been determined. Make a duct cable cut and omega rail. Make a duct cable installation

REL Omega: Install MCB 1-phase, MCB 3-phase, and 24VDC power supply on REL Omega. Install PLC, magnet contactor, thermal overload relay, and terminal on REL Omega.

Install push button and indicator light on the panel cover. Prepare two 3-phase induction motors in the area around the traffic light.

After all the components are installed on the panel box, the next step is to do the wiring process. The wiring process starts with the installation of the main circuit on the motor, which is by connecting the voltage source to the MCB and then to the main contactor terminal to the electric motor through the terminal.

The wiring process is continued by installing the port-com input. Make sure the port-com input is in accordance with the PLC specification used. For this type of PLC, we use negative com so that we give positive voltage to the push button. Next is the installation of the port-com output. Just like the com input, make sure the port-com output is also in accordance with the PLC specification used.

For this type of PLC, we will use a composite that is taken from a 24V DC voltage source. The wiring process is continued by installing the output circuit, which is to connect the PLC to the contactor and the indicator light. Next, do the installation of the input circuit, which is to connect the push button and the thermal overload relay contact to the PLC.

Next, do the check on the circuit that has been made Check the voltage source connectivity from the terminal to the MCB and power supply using ohmmeter Check the COM input and COM output connectivity using ohmmeter

Check the connectivity of the input circuit by using the ohm meter. Check the connectivity of the output circuit by using the ohm meter. Check the connectivity of the motor circuit by using the ohm meter. Make sure the three phases are safe and neutral, not connected to the phase. After all is confirmed, the next step is to connect the voltage source to the panel.

Check the voltage that enters the panel terminal using a voltmeter. The voltage of 3 phases is 380 volts and the voltage of 1 phase is 220 volts. The next step is to make a program. Make a program of the motor system in sequence using the ladder diagram on the CX Programmer software.

What you need to pay attention to when making a ladder diagram is when we use the push button NC as a stop button, then the ladder diagram is made NO. On the contrary, if we use the push button NO as a stop button, then the ladder diagram is made NC. The program that has been made will be uploaded to PLC.

What you need to pay attention to is that to connect this type of PLC to a computer, we use USB 2.0 type B cable or cable that is commonly used as a cable printer. After connecting PLC to the computer, make sure the computer can read the PLC status like this. Perform the program transfer procedure from computer to PLC like this.

Before operating the system, perform the operation of the control system on the PLC. Increase MCB 1 phase, then L3 will be activated. Press the PUSH button ON, then K1 and L1 will be activated. 5 seconds later, K2 and L2 will be activated automatically. Press the PUSH button OFF, then K2 and L2 will be turned off.

5 seconds later, K1 and L1 will automatically turn off. After the control sequence is confirmed, turn on the MCB 3 phases. Perform system operation. Press the PUSH button ON 1. The 1st motorcycle will turn on. 5 seconds later, the 2nd motorcycle will turn on automatically. Press the PUSH button OFF.

the second motor will be turned off. Five seconds later, the first motor will automatically turn off. When operating the PELSI system, make sure the I/O system is installed correctly, then the diagram is made correctly, and the migration process is done according to the procedure of the type of PELSI we use.

The most important thing is to work safely when doing the practical. Don't forget to clean and tidy the practical area after use. The program we made is just one example of a PLC application in the automated bus system. Of course, we can develop a PLC program according to the system we want.

And that's the video of learning to operate the TLC system. Hopefully it will be useful for everyone. And keep on working, creative and innovative. SMK can! SMK is great! Strong vocation strengthens Indonesia. Wassalamualaikum warahmatullahi wabarakatuh. Assalamualaikum warahmatullahi wabarakatuh. Peace and prosperity.

I, Anwar Subekti, as a video consultant operating the PLC system that you are witnessing. In my opinion, this video is already in line with the industry standards. However, the differences in this learning video are still reasonable, because this video is intended for learning. Thank you. Assalamualaikum warahmatullahi wabarakatuh.

Thank you.
