The Productivity Series 2000 and 3000 CPUs and remote controllers have OLED/LCD displays. The data can be system errors and information or user-defined messages programmed through ladder logic. Operators, maintenance, or programmer can use this information for running conditions, troubleshooting, or other items for the PLC system.
We will be looking at the CPU OLED/LCD on the productivity 2000 PLC. The eight control buttons will display the inputs and output for troubleshooting. System parameters like the real-time clock can also be set using the CPU display and control buttons. Custom messages displayed will be programmed in ladder logic. This will include scrolling messages and displaying tag information. Let’s get started. Keep on Reading!
Previously we created our first program using the Productivity Suite Software and transferred this to our connected Productivity 2000 Series PLC. One of the most important aspects of programming the PLC is to document. This will aid you and your team in programming, troubleshooting, and modifying the automation control system. Your documentation should read like a book so information can be quickly obtained when required. Time spent on the PLC documentation will be priceless when you go to read your program in 1, 3, or 10 years from now. The Productivity Suite software provides several different methods for documenting your PLC program.
Tag Names and Details, Task Names and Descriptions, Rung Comments and Instruction comments are the ways that we will be looking at documenting our PLC program. Let’s get started. Keep on Reading!
The Machine Simulator (MS) is part of the EasyPLC software suite. It has many built-in machines that are used to show different programming techniques. The robotic cell example is one of these machines. This will demonstrate a sequencer example. The logic will step through different steps in order to perform the task. In this case, an engine is lifted and placed onto a rack.
We will be using a Productivity Suite Programming Simulator to program this engine loader of the robotic cell. This will be done using Modbus TCP (Ethernet) for communications. Using the five steps for program development we will show how this sequencer is programmed. Let’s get started. Keep on Reading!
The productivity suite programming software has a debug mode. This will allow you to view and control the rung execution on your ladder logic code. These programming tools allow you to troubleshoot, find, and correct errors in the PLC programming logic.
We will be adding a couple of rungs to our exiting start-stop circuit we created last time in our productivity 2000 PLC. Using the debug mode we will explain the scan of the PLC and use these tools to sequence the logic. Let’s get started. Keep on Reading!
We will be creating our first Productivity 2000 Series PLC program. This will be done in ladder logic. The default physical IO and PLC task management will be discussed. Previously we communicated to our productivity 2000 PLC and automatically created the hardware configuration. We also set the hot-swap feature of our physical input and output cards on the controller.
We will now write our first PLC ladder logic program in our Productivity 2000 Series controller. This will be a simple start-stop circuit. We will download and then run the program, monitoring the ladder logic using the Productivity Suite software. Let’s get started. Keep on Reading!
We will be connecting the Productivity 2000 Series PLC with our computer running the Productivity Suite Software. A micro USB and an Ethernet (RJ45) communication link will be made to our programmable logic controller.
The latest Productivity Suite software version is 18.104.22.168. This is the programming software that we installed last time and will be used to communicate and create our logic for control.
We will be connecting the P2000 PLC to the Productivity Suite programming software with both the micro USB and an Ethernet (RJ45). Once connected we will be automatically setting the PLC configuration and writing this into the controller. Let’s get started. Keep on Reading!
