Abstract
The comprehensive control technique of many related marine equipment is an important means of marine automation.This paper introduced an integrated control automatic system whose communication platform was based on industrial Ethernet and PROFIBUS Fieldbus and whose control cells on SIEMENS S7-300PLC.By analyzing the status of the field,it also presented the basic hardwares of this system,inc.digital i/o nodes、control modules and communication function.Though planning communication protocol and using STEP7,programming tool and WinCC Configuration Softwares to programme,system functions were realized and the operation of the equipments inside the system was controlled effectively.This system adopted the advanced technologies in the field of the control engineering.It has been tested in the laboratory to improve the function and validate the reliability.
