Page 119: Modbus
Modbus Cellular Gateway 4.1.3 Modbus Modbus is one of the most popular automation protocols in the world, supporting traditional RS‐232/422/485 devices and recently developed Ethernet devices. Many industrial devices, such as PLCs, DCSs, HMIs, instruments, and smart meters, use Modbus protocol as the communication standard. It is used to establish master‐slave communication between intelligent devices. However, the Ethernet‐based Modbus protocol is so different from the original serial‐based protocols. In order to integrate Modbus networks, the IoT Gateway, including one or more serial ports that support RS‐232 and RS‐485 communication interface, can automatically and intelligently translate between Modbus TCP (Ethernet) and Modbus RTU/ASCII (serial) protocols, allowing Ethernet‐based PLCs to control instruments over RS‐485 without additional programming or effort. NOTE: When Modbus devices are connected to/under the same serial port of IoT Modbus Gateway, those Modbus devices must use the same protocol with the same configuration (i.e., either Modbus RTU or Modbus ...
