Practical Tips and Techniques
The productivity series of PLCs has a built in data logger. This easy data logger will log up to 64 tag values on a USB (Micro SD) storage device connected to the CPU. The logs will be stored in CSV (Comma Separated Values) file format. Logging can be triggered by the rising edge transition of … Read more
The C-More Micro HMI Panel software uses virtual components called Objects. Meters and Graphs are part of these objects. They can represent a range of numbers and are programmable to simulate the functions that you require on your automation project. This helps you produce simple, intuitive looking human machine interfaces. We will now look at … Read more
The productivity series of PLCs has a Drum and Sequencer instruction. Drum instructions are great tools. They mimic an electromagnetically drum sequencer. Have you ever seen the mechanisms of a music box? Ok so it’s a little drum with pegs that catch and flick the chimes in a particular sequence to play whatever tune is … Read more
We will now look at the C-More Micro Numeric Entry objects. The C-More Micro HMI Panel software uses virtual components called Objects. These objects are programmable to simulate the functions that you require on your automation project. Several of these objects can be placed on a one-panel screen and you can have multiple panel screens. … Read more
Shift registers will move (shift) bits in a word (register) to the left or right. If we look at an example of boxes moving along a conveyor belt, the boxes would represent the bits in the register. The movement of the conveyor would be the shifting of the register that represents the movement of the … Read more
The program control method and instructions will allow us to specify what parts of the logic get solved and when this happens. This will control how the PLC will scan and solve your logic in your program using a synchronous PLC Scan. Understanding the PLC program scan will explain the synchronous and asynchronous program scanning. … Read more
