In this tutorial, you will learn how to program a chain conveyor transfer using Do-More. The EasyPLC software suite includes a Machine Simulator (MS) with pre-programmed machines, including the chain conveyor. This machine can move boxes of various sizes along the production line, transferring them to different locations. We will use the Do-More Designer PLC … Read more
This tutorial is for beginners who are just starting to program PLCs. Using the EasyPLC simple conveyor, we will move a box back and forth on the conveyor. We will learn to write the PLC ladder logic program for this operation. Using the five steps to PLC programming development, we will determine what must be … Read more
The Machine Simulator (MS) is part of the EasyPLC software suite. It has many built-in machines that can be programmed. The chain conveyor is one of these machines. It will transfer large and small boxes on the line to different locations. The productivity series of PLCs will be used to program this virtual machine. Using … Read more
The productivity suite software now contains a plc simulator. The software is a free download and is available from automation direct. This software will now allow you to test or troubleshoot your program without the physical hardware present. The entire family of controllers can use the simulator. P1000, P2000, and P3000 emulation can happen on … 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
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
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 … Read more
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 … Read more
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 … Read more
