First I'm no PLC guy per say but they are using this device to simulate a plant where we built a lab size demo to do testing with. From what I understand this device has 16 outputs and 4 inputs but additionally it has another block that is not accessible unless we can flash the firmware to a newer version. What I’m in need of is the additional inputs so I can accurately simulate the plant. The makers of this product no longer support this model and is unwilling to provide me assistance in flashing it with the exception of a download that only seem to fail every time I try, I am just looking for options. Please if you can provide any assistance I would appreciate it greatly.
