Function

High-performance processing

It provides 100K word user memory and supports complex control programs, including bit logic, arithmetic operations, timers, counters and advanced control algorithms (such as PID).

The program scanning time is highly efficient (bit logic 0.5 ms/ thousand words, typical operation 2 ms/ thousand words), suitable for real-time control.

Multi-protocol communication

It is equipped with multiple communication interfaces (ControlNet, DH+, RIO, serial port), supporting high-speed data exchange with devices such as frequency converters, Hmis, and I/O racks.

The dual ControlNet ports support hot backup configuration (via 1785-CHBM), ensuring high availability and fast processor switching.

The serial port supports DF1 and ASCII protocols, and is suitable for program download/upload and point-to-point communication.

Flexible I/O configuration:

Supports up to 3072 I/O points and is compatible with 1771, 1794, 1746 and 1791 series I/O modules.

Supports 2-slot, 1-slot and 1/2 slot addressing modes, providing flexible hardware integration options.

Hot backup and Redundancy

Supports the ControlNet hot backup system (1785-CHBM), achieving rapid processor switching and highly reliable data transmission, suitable for mission-critical applications.

Memory backup

The RAM content is maintained using 1770-XYC lithium batteries, and non-volatile memory modules (1785-ME32, ME64, ME100) are supported to enhance data protection.

The battery status indicator light indicates low power and reminds you to replace it in time.

Diagnosis and Monitoring

Built-in diagnostic function, providing system status monitoring and fault detection.

Support network configuration and diagnosis via the 1784-KTCx communication interface card.

Programming support:

Programming is carried out using RSLogix 5 or Studio 5000 Logix Designer software, which supports programming languages such as ladder diagrams and function blocks.

Application scenarios

Manufacturing plant

In automotive manufacturing, food processing or electronic assembly production lines, complex sequential logic, robots, conveyor belts and sensor networks are controlled.

Supports up to 3,072 I/O points and is suitable for large-scale distributed control.

Process control

In the chemical, oil and gas or pharmaceutical industries, complex process control tasks such as PID regulation, flow control or temperature management are carried out.

The ControlNet network supports high-speed data interaction with HMI and SCADA systems.

Energy Management

In power distribution or renewable energy systems, manage switchgear, relays and monitoring devices to ensure highly reliable operation.

The hot backup function is suitable for critical mission environments and reduces downtime.

Material handling: In warehousing or logistics systems, control automated sorting, conveying and stacking equipment, and achieve efficient distributed I/O management through ControlNet.

Complex control system: Suitable for applications requiring advanced algorithms (such as PID, motion control, counting), supporting automatic/manual mode switching between analog and digital control.

Legacy system maintenance: Used for upgrading or maintaining old systems based on PLC-5, keeping existing equipment running, and integrating modern networks through ControlNet at the same time.
