2I2O-Modbus TCP relay

Feature of product 1. Support working in TCP server, TCP client, UDP mode. 2. It supports 4 client connections under the TCP server mode. 3. Support MODBUS TCP protocol and Kingview. 4. Supports online update procedures, which is very convenient for customers to customize procedures. 5. The device name can be customized, and the Chinese definition is supported. When there are many devices, there is no need to record the complicated IP number. 6. The heartbeat packet time can be customized, and the reliability of the network is restored 7. The 32-bit microcontroller (STM32F103C8) with the high-performance Cortex-M3 core is used instead of the 8-bit microcontroller on the market. The network chip uses the hardware protocol W5500 instead of the low-cost ENC28J60. Product description 1. Support TCP server, TCP client, UDP 2. Supporting 4 client connections in the TCP server.Assume that the local port is 5000.Port 5000,5001,5002,5003 can be connected to the TCP client. 3. Support TCP MODBUS protocol
