The Parameter segment is your PLC’s configuration files. Here, there is only one file of software logic, titled “MAIN”. The Program segment is your controller’s software logic. After selecting your desired components, you can complete the read by pressing the “Execute” button. The Read window will auto-populate with your project connection parameters, and a tree under “File Selection” allows you to select which components of the PLC you would like to read into your software. If your parameters are inputted successfully, and your hardware connection is active, you will receive a Successful Connection notice.Ĭlose out of the transfer/setup window, then read the project file by selecting the Online tab→ Read from the PLC. Once you’ve entered your communication information, test your connection by pressing “Connection Test”. Make sure your COM port number is correct, or the MELSOFT software will not be able to connect to the PLC. Specify your communication protocol for the PC (here we use Serial Port 1) and the PLC. To configure your connection, select the Online tab, then transfer/setup. In this example, we upload from an A2ASCPU, and so we create a project for that PLC. You can do this from GX developer using the 'Create New Project' button. Create your PLC-Specific Project File.īefore you can upload from your PLC, you'll need to create a project file of the appropriate PLC series and type. If your computer does not have a serial port, you will need to use a USB to RS232 adapter to connect to your PC’s USB port.Ģ.

This cable connects to the front, female port on your PLC and plugs directly into a serial port on your PC.

MELSEC F-Series PLCs use an SC-09 RS232 to RS422 adapter cable, which can be purchased from many places, including on Amazon. Need to upload a project from a MELSEC F-series PLC? You're in luck! This tutorial explains how to upload the software on a MELSEC F-series PLC using GX Developer, the MELSOFT developing platform for this line of controllers.
