A quick demonstration how to download the program from the Logic Designer into the Yokogawa STARDOM FCJ, FCN-RTU or FCN.

Logic Designer is the engineering tool that all Yokogawa PLC and RTU uses to program and upload and download the program into the and out of the controller.

Note that before you download the PLC program to the controller (PLC or RTU), you will have to build and compile the program (without error).

Another note worthy point is that, “Download” command will download the entire project to the STARDOM, causing the PLC to stop running. This will ESD your site, and should only be used under controlled setting. “Download Changes” will only download the changes that are detected in the logic. This will not stop the PLC from running, and will seamlessly transition the PLC program download without process interruption.
