Practical Tips and Techniques
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
We will now look at buttons and indicators that we can use on our C-More Micro HMI. 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 … Read more
Just about every program usually has some data comparison instruction. This is the ability to compare information from one area of the controller to another and act on results. The output of this comparison conditions the logical continuity of a rung. PLC Fiddle is a free online browser simulator and has the following compare contact … Read more
An array is a storage area for a group of common data type tags. They usually have some relationship with each other and need to be manipulated as a group. Previously we defined an array and use this in an indirect addressing program. It sequenced bits in an output card indirectly. We then looked at … Read more
We will now look at shapes like lines, rectangles, circles, and frames that we can use on our C-More Micro HMI. 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. Pushbuttons, Switches, meters, and graphs are just a … Read more
