Modbus TCP/IP User Manual
The document provides the basic communication parameters for a Modbus TCP/IP controller, including the default IP address (192.168.0.1) and the standard TCP port (502). It also lists the register address ranges for read/write, input, and discrete registers.
Detailed tables describe the format of each register type, the address limits (e.g., RW‑0‑FFFF for output registers, R‑0‑FFFF for input registers, RWB‑0‑FFFF for discrete outputs, and RB‑0‑FFFF for discrete inputs), and how to interpret the data stored in these registers. This manual is written in Japanese.
Covers: Modbus TCP/IP Overview · Controller IP Address · Communication Port · Register Types · Output Registers · Input Registers
Modbus 984 HMI Wiring Manual
The document describes the default communication parameters for the Modbus 984 HMI, including baud rate, parity, and stop bits for both ASCII and RTU modes. It also lists the default controller station number and the address ranges for control and status areas.
Detailed tables define the register and I/O address formats, showing output and input register ranges as well as discrete output and input bit ranges. A note explains how to configure special Modbus write commands when required by the connected controller. This manual is written in Chinese.
Covers: Communication Settings · Controller Station Number · Control and Status Areas · Register Address Ranges · Discrete I/O Ranges · Modbus Write Command Configuration
Modbus RTU 2W Master User Manual
The Modbus RTU 2W Master manual describes the communication parameters, including baud rate, data bits, parity and stop bits for both ASCII and RTU modes. It also specifies the default control address used by the device.
The document lists the register map for the device, covering output registers, input registers, discrete outputs and discrete inputs, as well as special Modbus write commands and retry behavior. Revision information and version details are included at the end of the manual. This manual is written in Japanese.
Covers: Communication Settings · Control Address · Register Map · Output Registers · Input Registers · Discrete Outputs
Modbus TCP/IP (6 Digits) User Manual
The document describes the basic network configuration of the Modbus TCP/IP (6 Digits) controller, specifying the default IP address, port number, and unit identifier used for communication. It also outlines the address ranges for various register types used by the controller.
Detailed tables list the output registers (W4‑n), input registers (WS3‑n), discrete outputs (B0‑b) and discrete inputs (B1‑b), showing the address ranges and data formats for each type. These tables serve as a reference for reading and writing data to the controller via Modbus TCP/IP. This manual is written in Japanese.
Covers: IP Configuration · Port Settings · Unit Identifier · Output Register Map · Input Register Map · Discrete Output Map
