How to use PLC programmer

The PLC programmer is the human-machine interface of the programmable controller system. Users can use the programmer to input, edit, modify and debug programs of the programmable controller.

After the PLC programmer is powered on, the word "PASSWORD" is displayed on the programmer. After pressing the CLR MONTR key, the password disappears. Press the CLR key again, and the address 0000 is displayed on the screen. Then various operations can be performed.

Memory Clear

The memory clearing operation must be performed in PROGRAM mode.

Clear all memory

The program in the memory and the YV06 action are completed. From the PLC STATUS, 110.6 is "1", indicating that the workbench indexing plate rotates to the right position, I10.0 is "0", indicating that the workbench indexing plate has not fallen back, and then Q4.7 is "0", the KA32 relay is not energized, the YV06 solenoid valve does not act, and the workbench indexing plate does not fall back and an alarm is generated. Treatment method: Manually operate the YV06 solenoid valve and observe whether the workbench indexing plate falls back to distinguish whether the fault is in the output circuit or inside the PLC.

A PLC programmer is a device used to program a programmable logic controller (PLC). It can be used to develop and test PLC programs. Here are the general instructions for using a PLC programmer:

Connecting the PLC programmer and PLC controller: First, you need to connect the PLC programmer to the PLC controller. The connection method can vary depending on the device and model. Usually, the PLC programmer needs to be connected to the PLC controller through a serial port, Ethernet port, or USB port.

Open the PLC programmer software: After the connection is successful, you need to open the PLC programmer software. Generally, the PLC programmer software provides a graphical user interface for writing, debugging and downloading PLC programs.

Create a new PLC program: In the PLC programmer software, you need to create a new PLC program. When creating a new program, you need to specify the type and model of the PLC, as well as the name and path of the program.

Writing PLC programs: In the PLC programmer software, you can use various programming languages ​​(such as ladder diagram, SFC, ST, etc.) to write PLC programs. When writing programs, you need to program according to the logical functions of the PLC and the actual control requirements.

Debugging PLC program: After writing, you need to debug the program to ensure that it can run normally. In the PLC programmer software, you can use the online debugging tool to debug the program and check the correctness and running effect of the program.

Download the program to the PLC controller: After the program debugging is completed, you can download the program to the PLC controller. In the PLC programmer software, you need to set the parameters and connection method of the PLC controller, and then download the program to the PLC controller.

In short, PLC programmer is an important tool that can help users develop and test PLC programs, realize automation control and optimize production processes. The use of PLC programmer requires certain professional knowledge and skills, and requires professional training and practice.
