Unitronics PLC Program with HMI Interface

Job ID: 37953933

Budget: $30 – $250 USD

I am seeking a skilled programmer with significant experience in Unitronics PLC SM43-J-R20 to develop a specific program. This program should include:

- HMI Interface: This should be capable of real-time data display and house the necessary control buttons for efficient operation.

- Control Buttons: Specifically, the interface should include on/off switches.

Your understanding and expertise in creating an intuitive interface will be highly valued in this project. Please demonstrate your previous successes and relevant experience in your proposal.

Attached is detailed documentation of attempt to upload program from the working PLC and the error message at the end.

Below is the Unitronics feedback after review our documentation.


Hello Mr. Shew and Mr. Ortega,
Unfortunately if the original programmer did not download the project with an upload enabled then it will no be possible to get the project off of that controller. A new project will have to be made. If the device is part of a system/machine that was purchased as a whole (not made in house) then there is a chance the machine builder will have the project for that PLC.

Unfortunately, We lost contact with the Programmer who did the code before we could get a copy of code.
Our objective is to get a program which is upload enabled. We will download it to a new Unitronics PLC and also keep it for future download in case any one of PLC failes.
