No Comments on EasyPLC Machine Editor – Design a Simulation

EasyPLC comes with many prebuilt machines for you to develop the programming logic. These can be modified, or new custom machines can be programmed using the machine editor. The machine editor comes as a standard feature of the EasyPLC Software Suite. The EasyPLC Machines Simulator editor is an easy-to-use tool enabling you to create easy, medium, or complex mechanical systems. These machine systems can include assembled mechanical, electrical, and electronic components.
If the components you need are unavailable in the library, you can use the components editor to create your mechanisms and devices. These machines help you to enhance your PLC programming skills. You can also replicate real, physical systems to be programmed virtually and avoid damaging the existing system. Alternatively, you can start programming and verifying your program before making the machine.
EasyPLC comes with over 40 prebuilt machines. We will be using the Machine Simulator Editor to create a new machine mixing tank simulation. It will include a tank, control panel, and operation indication. Let’s get started.

No Comments on Click PLC Analog Input Non-Linear Scaling

The Click PLC has automatic linear scaling for the analog inputs and outputs. What if the analog input or output is not linear? How do you handle this in the PLC? Look at the following tank. We can measure the height, which is linear, but the volume will not because of the shape of the tank.
We will look at an application to determine the volume in this tank. This will be based on the height of the liquid in the tank. We will then scale this non-linear volume of the tank to display the actual volume. Let’s get started.

No Comments on Productivity 2000 PLC Ladder Logic Counter

Most programmable logic controller (PLC) programs will include a counter instruction. The Productivity 2000 Series PLC has two different counter instructions for your program. These can be used in several different ways to adapt to your application. Basically, counters are used to count up or down to a specific limit. When the limit is reached, the output is turned on.
Counters can be made from a few different instructions from the PLC. The math instruction uses the one-shot (leading edge) input to add 1 to an internal register to keep track of the counter’s value. A comparison is used to compare this counter value to a set value (SV). The output is turned on if it is greater than or equal. Another input is used for the reset of the counter value. Copy is used to move the reset value into the counter value. This reset will usually override the counting application. Breaking down the counter’s essential operation will help us understand our application and how we can utilize counters in our automation programs.
The productivity suite software has Simple Counters (SCNT) and the Counters (CNT) instructions.
We will be reviewing these instructions and looking at how to implement them in our ladder logic program. Let’s get started.

No Comments on EasyPLC Palletizing Robot Programming Click PLC

The EasyPLC palletizing robot will demonstrate sequencing and robot control using a PLC. This palletization process will fill a box container with six cans. A servo-controlled gantry robot using x and y is used to do this operation. The complete box will then travel along to another conveyor to an unloading area. A robot will then pick up the box and place this on a pallet.
We will discuss and show you how to program this EasyPLC palletizing robot machine using the five steps for PLC program development. This will involve all the ladder logic to load and unload using the robot simulator. This PLC simulator will show sequencing instructions. A drum instruction in the PLC will be used with events and a counter to load the box with six cans. Another drum instruction in the PLC, with time, will be used to unload the container onto a pallet. An Automation Direct Click PLC will be used for this application, but the general methods can be used for just about any PLC on the market. Serial Modbus RTU communication between the machine simulator and the Click PLC will be used. An Ethernet connection will be used with the Click programming software. Let’s get started.

Timers are one of the first things you learn about programmable logic controllers. (PLC) Just about every PLC program will include timer instructions. The Productivity 2000 Series PLC has several different timer instructions for your program. We discussed the timed coil (TMC) and flasher coil (FLS) last time as part of the ladder logic output discussion. (Ladder Logic Output Instruction – Video)
We will now look at using the Simple Timer (STMR) and the Timer (TMR) instructions in the productivity suite software. Let’s get started.

The EasyPLC machining center loading robots will demonstrate sequencing and robot control using a PLC. Two input lines feed blanks to the robot. The robot will alternate taking the blanks and putting them into the CNC (Computer Numerical Control) machine. The robot moves the piece to the finished conveyor when the part has been machined. A three-axis robot loader will pick up the part and place this in a storage box on the roller conveyor.
Using the five steps for PLC program development, we will discuss and show you how to program this EasyPLC machining center. This will involve all the ladder logic to load and unload using the robot simulator. This PLC simulator will show sequencing and drum instruction programming using timers and events. An Automation Direct BRX Do-More PLC is used for this application, but the general methods can be used for just about any PLC on the market. Let’s get started.
