| Abstract: | The paper introduces a wireless correspondence sever. It can realize the Modbus-RTU master station protocol by STC Micro-control unit. The principle and circuit of the chip are introduced. This server is low cost. It solves the wireless correspondence problem between AB PLC master and other Modicon Micro PLCs in the far. It provides a practical and feasible method for the data exchange between the different type of PLCs. |
