For the safety precautions of the programmable controller system, refer to the User’s Manual for the CPU module. Let us start by creating a new structured project with Q series PLC.SAFETY PRECAUTIONS(Always read these instructions before using this product.)īefore using this product, thoroughly read this manual and the relevant manuals introduced in this manual and pay careful attention to safety and handle the products properly.The precautions given in this manual are concerned with this product.
Some of such modules are analog input, analog output, temperature module, and MODBUS module.
They are special modules that can be added to PLC hardware. Intelligent Function ModulesĪs with the device memory in CPU modules, intelligent function module devices can read data from and write it into their buffer memories using transfer instructions like MOVE.
An installation of GX Works 2 Software.īefore we delve into function blocks, let us first understand Intelligent Function Modules. Familiarity with Mitsubishi PLC Programming with GXWorks2. In order to follow along with this tutorial, you will need: This tutorial introduces the basics of function blocks and troubleshooting methods. Instances are a specific implementation of a defined function. They help reduce the time spent programming systematic processes/sequences as an instance can be created. It allows us to make changes before the circuit is implemented, reducing the risk of errors and accidents.įunctions and function blocks store their inputs/outputs in instance data for processing. And seventh, it helps to identify potential risks and hazards associated with the circuit program. Thus, it provides greater flexibility in experimentation. Sixth, it allows for testing different scenarios without physical changes to the control circuit. Why? Because physical testing can be affected by external factors. Fifth, it provides a more accurate representation of the circuit's behavior than physical testing. Fourth, you gain an understanding of how the program works, how it interacts with various inputs, and how it produces outputs. Third, it allows for the testing of the circuit program without the need for actual hardware, which can save time and resources. Second, you can identify design flaws and adjust parameters to improve the circuit's performance and safety. First, it allows for error detection in the control circuit program before it is implemented in real-life situations. Mastering the simulation process in Siemens Logo PLC can provide several benefits.
