This document describes the wiring instructions for the series HMI and each brand, including Modbus RTU 2W (Master) HMI default values, communication speed, controller station number, control area/status area, controller wiring instructions, controller Read/Write address definitions, etc.
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.
