Abstract ：The Siemens CP440 module and LECOM protocol are introduced. The method
of realizing LECOM protocol by CP440 module and the design thought and software
programming are also presented. The practical application proves that CP440 module is
stable and reliable when it communicates with LENZE 4900 by this protocol. The protocol
conversion method is also very suitable to be used in industrial control field.
