This document introduces the preset values, controller IP address, controller communication port, controller station number, controller wiring instructions, controller Read/Write address definition of Delta RTU-EN01 (Modbus TCP) human machine.
This document describes the Delta RTU-EN01 human‑machine interface controller, including its default IP address (192.168.0.1), Modbus TCP port (502) and station number (1). It also explains the wiring options and the automatic HMI detection mode.
Detailed tables list the read/write address ranges for basic registers, timer registers, counter registers, I/O module control registers, and the various relay contacts. The Modbus address mapping for each register type is also provided. This manual is written in Chinese.
