Customers with PLC control, please kindly pay attention to this notice: your control computer has PLC protection system inside. DON’T try to copy anything from the computer or vice versa; and DON’T insert U-sticks alike, otherwise a blank will spring up with the aim of protecting the computer but also interferes your operation.

We remind our customers of this issue after installation, but unfortunately one of our Tanzania customers is still caught with awkward situation.
