Specifications and Parameters
Hardware and Performance
- Processor Configuration: 266 MHz clock frequency, supports hot-standby protocol, equipped with mathematical coprocessor.
- Memory Structure: 1024 kB internal RAM (512 kB for data storage), expandable to 7168 kB program memory and 8 MB file storage via PCMCIA card.
- Instruction Execution Efficiency: 20 Kinst/ms for pure Boolean instructions, 15 Kinst/ms for a mix of 65% Boolean and 35% numerical instructions.
- I/O Capability:
- Discrete I/O: Unlimited Ethernet remote I/O (up to 31 branches, 28 slots per branch); local I/O disabled in hot-standby mode. Each distributed Modbus Plus network supports 31744 inputs/outputs.
- Analog I/O: Unlimited Ethernet remote I/O (31 branches × 28 slots); local I/O disabled in hot-standby mode. Each distributed Modbus Plus network supports 1984 inputs/outputs.
- Special Function I/O: Integrated high-speed interrupt inputs (supporting precise timestamping) and serial links.
Communication and Networking
- Built-in Interfaces: 1 Modbus Plus, 1 Modbus (RS232/485), 1 USB, and 1 multimode fiber optic interface (for hot-standby master-slave interconnection, up to 4 km).
- Expansion Modules: Supports 6 optional modules (Ethernet, Modbus, Modbus Plus, Profibus DP, Sy/Max).
- Connectivity: Local support for 6 Ethernet TCP/IP, 6 Modbus Plus, and 6 Profibus DP connections; distributed/remote support for networks like AS-Interface.
Hot-Standby Features
- Master and slave PLCs are interconnected via MT-RJ fiber optic interface. Functions such as fast tasks and I/O interrupt tasks are disabled in hot-standby mode.
Electrical and Environmental Parameters
- Power Requirement: Backplane current of 2500 mA, requiring external power supply.
- Certifications and Compliance: Certified by UL, CE, CSA, GOST; RoHS compliant since 0901; SVHC-free per REACH; classified as a Green Premium product.
- Protective Treatment: Surface coated with Humiseal 1A33 conformal coating for adaptability to harsh environments.
Physical Characteristics
- Installation: Compatible with 2/3/4/6/10/16-slot racks, supports 2 local racks.
- Interface Types: RJ45 (Modbus bus), SUB-D 9 (Modbus Plus), MT-RJ (fiber optic).
- Status Indicators: Ethernet activity (green LED) and Ethernet collision (red LED).
Applications and Compatibility
- Industrial Scenarios: Suitable for automation systems requiring high reliability, such as redundant control in energy and manufacturing sectors.
- Network Deployment: Supports 63 distributed I/O stations and remote I/O stations (16 X80 Ethernet racks / 31 Quantum Ethernet racks / 31 S908 racks).
Notes
- Partial task functions are limited in hot-standby mode, requiring configuration based on actual requirements.
- Use PCMCIA cards for memory expansion to ensure compatibility and stability.
