Rescue program to another new PLC UNITRONICS

Recommended Posts

Hi, I would like to know the easiest way to copy the program from one JZ10-11-R10 PLC to another. The reason is because one has been damaged and I want to replace it, but I don't have the program on my PC, since the programmer has closed his company.

Thank you, I have written to you. But the problem is knowing if there is a company that repairs these modules electronically, because it doesn't turn on and that's why I don't have the possibility of copying the program to install it in another new module.

In this case, I think the chances of saving the PLC and the programs in it are very small.

I repaired such PLCs, but all the problems they had were relay malfunctions and broken buttons on the keyboard.

Two PLCs that could not be repaired have a damaged processor which in such a PLC is not isolated from the inputs. Users accidentally applied high voltage to the PLC input and unfortunately it could not withstand such abuse.

The CPU power pins in the destroyed in this way PLCs are shorted, and the internal power supply cannot run on a shorted CPU. Therefore, look for an electronics specialist to measure the supply voltage (3.3V) of the STM processor and if it is present - there is a chance to clone the program.
