NA-RTU CPU401-1101 Feature Introduction
- RTU features an Ethernet interface, an RS232 interface, an RS485 interface, a ZigBee wireless communication interface, digital input interfaces, digital output interfaces, analog input interfaces, and interfaces for I/O expansion modules, among others.
- Supports I/O expansion, with a maximum expandability of up to 8 I/O modules;
- Program the RTU via the Ethernet interface to implement complex logic control, as well as data acquisition and transmission.
- Supports I/O interfaces, RS485 fieldbus interfaces, and wireless ZigBee network data acquisition functionality;
- Supports the proactive upload of RTU alarm data to the SCADA system (upstream communication protocol: IEC60870-5-104 or MODBUS TCP);
- Supports multiple data acquisition methods for indicator diagrams;
- Supports electrical power diagram measurement and auxiliary analysis: Utilizing motor electrical data to indirectly measure the “indicator diagram” in real time, thereby assisting in the analysis of oil well operating conditions.
- RTU supports power-loss data retention functionality;
- Features a calendar clock and supports network-based time synchronization (the calendar clock can maintain its time for 3 months even after power failure);
- Supports large-capacity, time-stamped data caching (10 days) for RTU monitoring data in the event of an upstream network interruption;
- Supports on-site monitoring, control, configuration, and debugging of RTUs from laptop computers;
- Supports remote configuration and parameter modification functions;
- Built-in temperature measurement module for real-time monitoring of ambient temperature;
- Equipped with a PT100 temperature interface for real-time monitoring of ambient temperature;
- Meets the requirements of outdoor and complex electrical environment applications.
Product Features
Stable and reliable
The fully intelligent I/O design and a series of safety and reliability features provide robust assurance for the system’s safe and reliable operation.
Low-power design
- Isolation and protection measures are implemented between the CPU, I/O signals, communication networks, and power supply.
- Possesses excellent electromagnetic compatibility;
- Supports password setting to protect users’ intellectual property.
Comprehensive functionality
- Open network, 100M Ethernet, supports MODBUS/TCP protocol;
- Features one Ethernet port and four built-in serial ports (one RS-232, three RS-485);
- Features 12 DI inputs (24V), 10 DO outputs (relays), and 6 AI inputs (5 channels of 4–20mA, 1 channel of two-wire RTD);
- The rich set of built-in integration features not only provides various standard operators, control function modules, and standard functions, but also offers practical function modules such as PID and SOE (Sequence of Events), enabling cost-effective solutions for high-end control applications.
- Integrated hardware watchdog, supporting extensive fault monitoring and diagnostics;
- Comprehensive LED indicator functions: comprehensive LED indicators for power, module operation, faults, communication, and more;
- Smart module with powerful self-diagnosis capabilities—when a fault occurs during module operation, it can automatically reset and restart itself.
Good value for money
- The CPU module integrates an Ethernet interface (saving on a separate network module);
- The serial communication module provides a rich set of communication interfaces.
- Programming debugging is convenient and fast;
- Supports the IEC61131-3 international standard;
- It features system configuration, database configuration, online database querying, online ladder diagram monitoring, online structured text debugging, online process debugging, and online ladder diagram modification.
- The unique data security output function gives the control device enhanced security features.
- Supports multiple programming languages: Ladder Diagram LD, Instruction List IL, Structured Text ST, Sequential Function Chart SCC, and Function Block Diagram FBD;
- Supports programming in both Chinese and English, greatly enhancing the readability of the program.
- Provides intelligent graphic and text editing features with a user-friendly interface;
- Supports Ethernet-based remote programming and debugging;
- User programs and data are permanently saved.
