*DEEP DIVE CONVERSATION* Okuma OSP P100: How to export the D300win APP & unzip a PLC Project backup
This YouTube video describes how to work with PLC projects on Okuma OSP P100 and potentially OSP P200 machines using the D300win software. It explains how to execute the software from a GHOST image, open existing projects, and specifically focuses on unzipping and restoring a backed-up project file with a ZWT format. The goal is to demonstrate how a previously made modification to the PLC logic, involving adding a parallel output, can be verified by opening and reviewing the restored project. The process involves navigating the software, handling common errors during decompression, and ultimately saving the verified project.
Key Themes:
Accessing D300win and PLC Projects: The video demonstrates how to access the D300win software and associated PLC project files by copying the contents of the machine's hard drive (presumably the "DIN" partition) to a computer and running the executable. This suggests a method for offline access and manipulation of the PLC logic.
PLC Project Structure and Location: The source identifies a "projects" folder within the copied directories as the location where the PLC project files are stored. This highlights the organized nature of the PLC software within the Okuma system.
Modifying and Saving PLC Logic: The demonstration shows a specific modification to a Programmable Organization Unit (POU) named "CHK1," specifically within block 21. This involves adding a parallel connection. The process includes opening the project, reviewing the original logic, making modifications, and the final step of saving the project.
Backup and Restore Process: The core focus of the video is demonstrating how to restore a zipped backup of a PLC project. This involves unzipping a file with a ".ZWT" extension, which the source identifies as a common zipped format for these projects. The success of the restore is verified by re-opening the project and observing the previously made modification.
Project Compilation and Build: The source mentions steps like "compiló el programa" (compiled the program) and "la construcción de la cross reference" (the construction of the cross reference), as well as the option for a more advanced "reveal de proyecto" (project reveal) compared to a simple "make." This indicates that working with Okuma PLC projects involves a build process beyond simply saving the logic.
Most Important Ideas/Facts:
D300win is the software for connecting to and modifying the PLC on Okuma OSP-P100 and likely OSP-P200 systems.
Accessing the PLC project files offline is possible by copying the machine's hard drive contents.
PLC project files are typically located in a "projects" folder.
Okuma PLC projects are often backed up in a zipped format with a ".ZWT" extension.
Restoring a project involves unzipping the ".ZWT" file.
Modifications to the PLC logic within POUs (like CHK1) are possible using D300win.
A build process (compilation, cross reference, reveal) is involved when working with these projects.
