Huaqiang Wang · Industrial Instrumentation & Automation · 2012
In the past GE series PACSystems PLC,mostly through the allocation of special communication module is adopted to realize and other subsystems in Modbus communication.In this paper,the shortcomings of the scheme are analyzed,with GE PACSystems RX7i/RX3i and Bently 3500 between communication as an example,based on the Modbus RTU communication improvement scheme,and its realization process is described in detail.
