METHOD AND SYSTEM OF OPTIMIZATION FOR INPUT OR OUTPUT DATA TRANSFER DURING PROFIBUS CYCLIC COMMUNICATION

摘要

Disclosed is a method for optimization of input and output data transfer during profibus cyclic communication in a networked computerized industrial process control systems. The method includes connecting a relay with a computer using a communication module with configuration utility, and selecting a parameter required by a PLC master device. Further, the method includes selecting bit information required by the PLC master device. Furthermore, the method includes configuring the relay as per data sequence and selection, wherein the relay is configured by using any one of adding multiplication factor in current value of the parameter and sending only useful bytes of the parameter in a PLC register. Thereafter, the method includes configuring the PLC registers as per memory map selection, configuring the PLC master device with previously used .GSD file, and reading/writing operation with maximum data utilization.
