Productivity 2000 PLC Ladder Logic Math

Productivity 2000 PLC Ladder Logic Math

Math instructions perform mathematical calculations. The Productivity 2000 Series PLC has math instructions that you can use in various applications. We will look at the Data Statistics (DATA) and the Math Editor (MATH).
Productivity 2000 PLC Ladder Logic MathWe will demonstrate both of these instructions using the examples in the help file. An average wind speed will be calculated using the data instruction based on six different inputs. Converting Celsius to Fahrenheit degrees will be done with the math instruction for an oven temperature. The automation system that you implement may involve these instructions. You will require using these instructions in your commissioned programs as a system integrator.
Let’s get started with the Productivity 2000 Series PLC Math Instructions.

EasyPLC Machine Editor – Design a Simulation

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 Machine Editor - Design a SimulationEasyPLC 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.

Productivity 2000 PLC Ladder Logic Counter

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.
Productivity 2000 PLC Ladder Logic CounterCounters 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.
PLC Ladder Logic Programming Sample CodeThe productivity suite software has Simple Counters (SCNT) and the Counters (CNT) instructions.
Productivity 2000 PLC Ladder Logic CounterWe will be reviewing these instructions and looking at how to implement them in our ladder logic program. Let’s get started.

EasyPLC Palletizing Robot Programming Click PLC

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.
EasyPLC Palletizing Robot Programming Click PLCWe 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.

Timing Diagram NOT Just Used for a Timer

Logic circuits in a PLC ladder logic program are either on or off. The inputs change, which will affect the outputs. This can be expressed in a timing diagram. The timing diagram or chart will show you how the ladder logic program will respond to the changing states of the inputs and outputs.
Timing Diagram NOT Just Used for a Timer
This visual method is an excellent way of understanding how the PLC ladder logic functions. We will discuss a timing diagram and how it is used for timers, counters, and ladder logic. This will help in understanding or troubleshooting your PLC programs. 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)
Productivity 2000 PLC Ladder Logic TimersWe will now look at using the Simple Timer (STMR) and the Timer (TMR) instructions in the productivity suite software. Let’s get started.
