HMI from Hell...

[Dr. Kindorf]

I inherited a machine project that has a Mitsubishi FX1s, and is connected to an HMI that was fitted with the machine in China. Apparently they didn't test the machine before it left, because the control transformer was connected backwards,and as a result incinerated most of the controls. Here is my dilemma: I have built new controls for the machine however; the data I need to determine the original scaling info for a length encoder on the machine is in the HMI, and I have no software to retrieve it. If they hadn't already built their product database around the original scaling parameters written to the PLC, I could just easily start over, but without knowing the DDIV variables that the HMI sends, it would be very difficult to match the exact scaling they have utilized . The HMI is called a "TouchWin" Model OP320, manufactured by Xinje Electronics. Does anyone know where I may obtain a copy of the software for one of these HMI's? Any assistance would be greatly appreciated.
