C-More Micro HMI Object Numeric Entry

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. This helps you produce simple, intuitive looking human-machine interfaces.

Continuing from last time we will now look at the numeric entries that we can use with our HMI micro panel. Let’s get started. Continue Reading!

PLC Fiddle Shift Register Challenge

Shift registers will move (shift) bits in a word (register) to the left or right.
PLC Fiddle Shift Register Challenge
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 boxes.
PLC Fiddle Shift Register Challenge
Shift registers are a form of sequential logic, which involves the present inputs and the prior history. All of the prior history is remembered.
We will be making a shift register in PLC Fiddle with the instructions provided. The output of the shift register will then be looked at for a reject area. Let’s get started. Continue Reading!

Productivity 1000 Series PLC Program Control

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.
Individual ladder logic programs get solved left to right, top to bottom. The result of the rung before is available for the next rung. Task Management provides a method to clearly see the overall flow of your PLC program. Looking into the folders of the task management we can see blocks of code. These blocks contain the ladder logic that will solve our logic. Instructions within the ladder logic code can also determine how the PLC will solve the logic.

C-More Micro HMI Object Buttons and Indicators

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 you can have multiple panel screens. This helps you produce simple, intuitive looking human-machine interfaces.

PLC Fiddle Compare Instruction Challenge

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 instructions.
= (if Equal contact)
<> (if Not Equal contact)
> (if Greater Than contact)
>= (if Greater Than or Equal contact)
< (if Less Than contact)
<= (if Less Than or Equal contact)
We will be looking at these instructions along with some programming challenges. As a system integrator, this ability can prove very useful to you in the field when commissioning your automation system. We will look at these compare instructions and show the parameters required to program them. Our compare challenges will help you gain a good understanding of how we can use compare in the PLC. Trying these challenges with PLC Fiddle is fun and will help you with PLC programming. Let’s get started. Continue Reading!
