The ADM-5832G is an industrial-grade 2 serial RS-485/422 Modbus gateway serial port device that allows users to easily integrate Modbus Ethernet devices with Modbus serial devices. DIN rail mounting, DC9-48V power supply, internal Integrated ModbusTCP, ModbusRTU and Modbus ASCII protocol.   1, MODBUS agreement in several categories, what is the difference?   MODBUS RTU:RS-485/422/232 serial communication, master-slave structure, a master, multi slave.   MODBUS ASCII:RS-485/422/232 serial communication, master-slave structure, a master, multi slave.   MODBUS TCP: Standard 10/100M Ethernet port communication, master slave structure, multi master, multi slave.   2, under what circumstances do you use the MODBUS gateway server?   (1) the RS-485 port collection terminal is connected to the PC of the configuration software through ethernet;   (2) PLC and touch screen need to communicate with RS-485 terminal when it is collected;   (3) multi host MODBUS protocol communication;   (4) MODBUS RTU protocol network access MODBUS TCP protocol network. 2 Port RS485/422   MODBUS gateway server   ADM-5832G   Function Brief   MODBUS protocol is one of the most widely used protocols in the electronic equipment industry. It has become a universal industrial standard. Through this protocol, various MODBUS devices (such as PLC, DCS, HMI, various instruments, etc.) can communicate with each other through a network or serial link. Nevertheless, the MODBUS protocol that uses the serial port and the Ethernet is different, so a gateway is needed to complete the communication transformation between the two protocols. ADM-5832G is a product dedicated to communicating MODBUS TCP devices and MODBUS RTU/ASCII devices.   ADM-5832G is a multifunctional 2 Port RS-485/422 serial MODBUS gateway, which integrates MODBUS TCP, MODBUS RTU and MODBUS ASCII protocol, and the device can be configured flexibly through serial port software RS485 or RS422 mode, the user can easily use it to seamlessly integrate MODBUS Ethernet devices with MODBUS serial devices.
