Abstract

The characterdisplayer which can communicate with many kinds of PLCs is widely used in the industrial field. The PLCs provided by different manufacturers, differ in protocol formats, and are incompatible with each other. So it's meaningful to develop the characterdisplayer which is compatible with a variety of protocols. This paper adopts the idea of reconfiguration in the frame organization layer of the PLC communication protocol,and the scheme is widely used in characterdsplayer products.

Key words： reconfigurable;layered protocol;protocol interface;HEX code
