This is the instruction set and communication manual of Modicon TSX Neza programmable controller. It mainly introduces the ladder diagram programming method and instruction set of the controller
The manual introduces the Modicon TSX Neza programmable controller and explains how to use the PL707WIN software for both instruction‑list and ladder‑diagram programming. It covers the full range of Boolean, numeric, and special function block instructions, providing examples and programming guidelines.
It also describes the controller's communication options, including TER port, MODBUS/JBUS, and UNI‑TE modes, and explains system bits and words used for fault detection, time/date handling, and diagnostics. This manual is written in Chinese.
| Supported communication modes | MODBUS, UNI‑TE, TER |
|---|---|
| Number of instructions | over 1000 |
Use the programming terminal to set the date and time, or update them via the system words.
The controller provides a TER port, MODBUS/JBUS interface, and UNI‑TE (ASCII) mode for communication.
Specific system bits represent different fault conditions such as output failure, sensor power fault, internal hardware fault, and communication errors.
