PLC Fiddle Math Challenge Examples

PLC programming will often involve math equations that need to be solved. Every manufacturer of programmable logic controllers will include math logic for you to use in your programs. Numbering systems play an important role. You can usually perform math using BCD (Binary Coded Decimal), Binary or Floating Point. Here is a link that will review the numbering systems in the PLC:
What everyone ought to know about PLC numbering systems
PLC Fiddle Math Challenge Examples
PLC Fiddles provides four basic BCD math and a move function for our circuits. Add, Subtract, Multiply Divide and Move. We will look at these math instructions and show you the parameters required to program them. Our math challenges will help you gain a good understanding of how we can use math in the PLC. Trying these challenges with PLC Fiddle is fun and will help you with PLC programming.
Let’s get started. Continue Reading!

PLC Fiddle Counter Challenge – Counters

Counters are used in a lot of PLC programs that I have seen. A timing chart is a secret behind understanding the counter that you need in your application. Making a timing chart before writing the program will ensure that all of the information will be accounted. The secret to using counters is a good review of using these timing charts.
PLC Fiddle Counter Challenge - Counters
PLC Fiddle has three different counter instructions for us to use in our programs. Count UP, Count Down and Reset. We will discuss the counter parameters and the three different instructions. Our counter challenges will help you gain a good understanding of how counters work in the PLC. Let’s get started. Continue Reading!

PLC Fiddle Timer Challenge – Timing Instructions

Timers are present in just about every PLC program that I have seen. A timing chart is a secret behind understanding the timer that you need in your application. Making a timing chart before writing the program will ensure that all of the information will be accounted for. The secret to using timers is a good review of using these timing charts.
PLC Fiddle Timer Challenge - Timing Instructions - On delay Off delay Pulse output
PLC Fiddle has three different timing instructions for us to use in our programs. On-Delay, Off-Delay, and Retentive Timers. We will discuss the timer parameters and the three different instructions. Our timer challenges will help you gain a good understanding of how timers work in the PLC. Let’s get started. Continue Reading!

PLC Fiddle Basic Gate Ladder Logic

Last time we discussed the free virtual plc simulator called PLC Fiddle. It will enable you to create simple PLC ladder logic code within your browser. This is an ideal way in understanding PLC concepts for industrial automation. All of the basic PLC instructions that come with most plc units have been incorporated into this virtual PLC software.

PLC Fiddle Video – This will demonstrate the basic functions of the PLC simulator.
Understanding and creating your own programmable logic controller programs on the ladder can be fun. We will be starting with the basic gate logic circuits and convert these to ladder logic.
We will be looking at the AND, OR, NAND, NOR, EXOR, and EXNOR logic circuits using PLC fiddle. This will get you involved in learning and understanding PLC programming. Let’s get started. Continue Reading!

PLC Fiddle – Online Editor and Simulator

I have recently come across a free virtual plc simulator called PLC Fiddle. It will enable you to create simple PLC ladder logic code within your browser free. This is an ideal way in understanding PLC concepts for industrial automation. All of the basic PLC instructions that come with most plc units have been incorporated in this virtual cloud PLC software.
PLC Fiddle is currently in an early stage of development but is functional enough to be helpful to you in learning and understanding PLC concepts. We will be reviewing this online plc editor and simulator software and create a few common basic circuits. Using the simulator we will test our circuits and monitor our PLC programs (circuits). Let’s get started. Continue Reading!
