This document is about the wiring instructions for the Koyo K-Sequence series HMI with various brands. The document includes the default values of the HMI, communication rate, controller station number, and the definition of control and status areas. It also provides the wiring methods for different series of HMIs with controllers, as well as the read/write address ranges for controller registers and contacts.
This manual describes the communication ports of the Koyo K-Sequence controller, including RS‑232 and RS‑485 connections, pin assignments, and wiring details. It lists the supported baud rate and connector types for each interface.
The document also contains a complete register map and bit‑level definitions for inputs, outputs, relays, timers, counters, and special functions, along with error messages and notes for proper configuration. This manual is written in Japanese.
| RS-232 Baud Rate | 9600, 8 data bits, odd parity, 1 stop bit |
|---|---|
| RS-232 Connector | 9‑pin D‑SUB |
| RS-485 Connector | 9‑pin D‑SUB male with terminal block |
The RS‑232 interface uses 9600 baud, 8 data bits, odd parity, and 1 stop bit.
The RS‑485 port uses a 9‑pin D‑SUB male connector with a terminal block.
Pin 6 must be connected to ground (GND).
The manual displays “Error 6 … Command Can Not be Executed.”
