This document introduces the Modicon TSX series human-machine interface and the wiring instructions for various brands. It includes default values such as communication rate, controller station number, control area/state area, as well as specific instructions for RS-232 and RS-485 wiring. It also introduces the definition of Read/Write addresses for the controller.
This guide provides the default communication parameters for the Modicon TSX (Uni‑Telway) human‑machine interface, including a baud rate of 9600, 8 data bits, odd parity, and 1 stop bit. It also specifies the default controller station number and the memory areas used for internal, system, and input data.
Detailed wiring diagrams are given for RS‑232 and RS‑485 connections to various DOP series controllers, along with the required Modicon Uni‑Telway cable (TSX PCX 1031). Register and bit address formats are listed, and differences between Modicon and Uni‑Telway communication protocols are explained. This manual is written in Chinese.
| Default communication speed | 9600 baud, 8 data bits, odd parity, 1 stop bit |
|---|---|
| Default controller station number | 2 |
| Internal word address range | %MW0 – %MW65534 |
| Internal bit address range | %M0:0 – %M65534:15 |
The default communication speed is 9600 baud, 8 data bits, odd parity, and 1 stop bit.
A Modicon Uni‑Telway dedicated communication cable (TSX PCX 1031) must be used.
The default controller station number is 2.
Internal word memory can be addressed from %MW0 to %MW65534.
