Function

High-performance processing: It provides 32K word user memory and supports complex control logic and data processing.

Fast scanning time (0.9 milliseconds per K characters), suitable for high real-time applications.

Communication capability: Built-in RS-232 port supports multiple protocols (DF1, DH-485, ASCII, Modbus RTU). The default configuration is DF1 full-duplex with a baud rate of 19.2K.

The DH+ port supports high-speed and long-distance communication (with a maximum baud rate of 57.6K), making it suitable for multi-point networks and message passing with other PLCS such as PLC-5 and ControlLogix.

Support the extension of multi-point networks through the 1761-NET-AIC adapter.

Flexible configuration: Supports up to 3 local I/O racks and 30 I/O module slots, adapting to various I/O requirements.

Compatible with a variety of discrete, analog and dedicated I/O modules.

Programming and Diagnosis: Use RSLogix 500 software for ladder logic and structured text programming, supporting advanced instructions (such as file processing, sequencers, diagnosis, shift registers, etc.).

Provide status indicator lights (operation, fault, battery, etc.) for convenient fault diagnosis.

Support online programming and Flash EPROM firmware upgrade.

Reliability and backup: Battery-supported RAM and Flash EPROM backup to prevent program loss.

Optional ControlNet or PLC-5 backup modules are available to enhance the system's fault tolerance capability.

Modular design: Installed in slot 0 of the SLC 500 rack, powered by the backplane, simplifying system integration.

Application scenarios

Small and medium-sized process control: Applicable to small and medium-sized automation projects such as material handling, packaging equipment, and conveying systems.

HVAC control: Used in building management systems to control heating, ventilation and air conditioning equipment.

SCADA system: Integrated with HMI or SCADA systems via RS-232 or DH+ ports to achieve remote monitoring and data acquisition.

Distributed I/O system: Supports distributed I/O control through communication adapters and scanners, suitable for large-scale factory automation.

High-reliability industrial environment: Rapid scanning and reliable communication make it suitable for production lines that require real-time control, such as automotive manufacturing, food processing, and metal processing.

Traditional system maintenance: As a discontinued product, it is suitable for the replacement or upgrade of the existing SLC 500 system, extending the equipment's lifespan.
