Thanks for information. I will check for SD card inside the controller and if there are some file on it I will write again here.

I want to ask one more question in this topic. How can I back up the project from the controller? I don’t want to upload it with editing purposes, I need to have it, if something happened to the hardware. Is it possible to use SD card or other way to get in (in compile form for example)? I need to have in case of controller problem and be able to load it in new PLC.

Thnaks for fast responce. I expexted this answer. The model of the controller is V350.

Hello, This is my first post and first time I face Unitronics PLC. We have customer who has HVAC systems base on Unitronics PLC. The problem is that our customer doesn’t have the PLC project, so is impossible to change some of the controls of the system. I connected to the PLC by ethernet and try upload the project but get the following message: “This project cannot be uploaded because: -the option Burn Upload was not selected when the project was downloaded, or – due to incomplete data in the PLC”. So, I want to ask Unitronics experts if they is some way to buy pass this message or nothing can be done? Thanks in advance for you time.
