【Abstract】 A communication control system of PLC based on PROFIBUS DP was designed aiming at acrylic fibers product lines. It includes control layer and local layer. The former is used with MPI communication mode, and the latter is used with PROFIBUS-DP communication network. The communication process and the system settings are described in this paper as well as the realization of soft programs and anti-interference technique of the master PLC with the slave PLC and the master PLC with the inverters. The system is easily enlarged and has characteristics of effective anti-interference, fast Communication and high control precision.更多还原
