Abstract: This paper describes the design of communication protocols between computer and the PLC controller and its programmingbased on the integrated system designing method.It proposes the detailed protocols used in automated storage/retrieval system. These realistic protocols and programs show high simplicity, low requirements on media and at the same time having the ability of monitoring communication process. It is suitable for the network of point-to-point as well as multi station bus structures.
