Practical Tips and Techniques
The EasyPLC machining center loading robots will demonstrate sequencing and robot control using a PLC. Two input lines feed blanks to the robot. The robot will alternate taking the blanks and putting them into the CNC (Computer Numerical Control) machine. The robot moves the piece to the finished conveyor when the part has been machined. … Read more
If you are looking to purchase a PLC system, there are three key components that you should look for. If your current system does not contain these features, you need to replace it with one that does as soon as possible. The three most important features you should look for in your new PLC system … Read more
The High-Speed discrete inputs can be configured to measure the amount of time between pulses. When you want a scaled value representing a speed or rate, the high-speed input timer is a better option for pulse rates below 5 kHz. This is compared to using the high-speed input pulse counting selection. The BRX Do-More series … Read more
A human-machine interface (HMI) is present in some form for every PLC. The HMI connects a user to a machine system to exchange information or control data. This interaction with the system can be through hardware or software. HMIs offer different people information and control in many ways for the automated system. Operators, supervisors, mechanics, … Read more
Developing a programmable logic controller (PLC) program can be broken down into five steps. These programming steps are as follows: Five Steps to PLC Program Development Step 1 – Define the task Step 2 – Define the Inputs and Outputs Step 3 – Develop a logical sequence of operation Step 4 – Develop the PLC … Read more
Programmable logic controllers (PLC) use a cyclic scan. The time that it takes to complete one scan is called Scan Time. Typical scan times range from 10 milliseconds to 10 microseconds. This translates from 0.01 to 0.0001 seconds per PLC scan. Understanding how the program scan will help us in programming and troubleshooting the PLC. … Read more
