Global only, the exclusive supply a name <Protocol Interface Adapter> adapter, designed for some of the inverter used in automated machinery developed. When using the inverter needs to be replaced when damaged, the original model has been discontinued, looking for alternate models are generally not a problem. However, if the original circuit design is the use of serial communication, and to find a replacement model becomes impossible task. Give some common examples such as the textiles industry : Rieter Carding C50/C51/C60, Unilap E30 etc., the printing industry : Stahl Rotary Feeder RD78.1 etc., and the hardware industry, the food processing industry etc.
