Practical Tips and Techniques
The High-Speed Input Pulse Catch will set an output that can be seen by the PLC ladder logic scan in response to an input pulse. Inputs that are too fast to reliably be seen by the ladder logic scan time will be seen. The BRX Do-More series of programmable logic controllers have built-in high-speed inputs. … Read more
The Machine Simulator (MS) is part of the EasyPLC software suite. It has many built-in machines that are used to show different programming techniques. The warehouse stacker example is one of these machines. Pallets are loaded and unloaded into the stacker machine. A maximum of 30 pallets can be stored. The stacker will work as … 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
The Machine Simulator (MS) is part of the EasyPLC software suite. It has many built-in machines that are used to show different programming techniques. The industrial mixer is one of these machines. When the start pushbutton is energized it will fill up a tank until the lower level sensor is detected. The mixer blades will … Read more
The BRX Do-More series of programmable logic controllers have built-in high-speed inputs. These inputs can function in Counter, Timer, or Pulse Catch modes. Every CPU will have either 6 or 10 high-speed inputs (HSI) available, depending on the model. These inputs can be used for input frequencies from 0 to 250Khz. 250Khz represents 250000 input … Read more
The Machine Simulator (MS) is part of the EasyPLC software suite. It has many built-in machines that are used to show different programming techniques. The paint line is one of these machines. It will use a bit shift (shift register) to track bottles along a conveyor belt. All the bottles will be detected using photocells … Read more
