Functional Features Base hardware platform supporting multiple firmware variants for different automation applications. Integrated SERCOS optical real-time bus for high-speed servo drive communication. Soft PLC function compliant with IEC61131-3 standard. Supports multi-axis motion functions including electronic cam, flying saw, gantry synchronization and interpolation. Ethernet interface for HMI connection, engineering download and remote diagnosis. USB port supports program backup and data export. Hardware watchdog circuit monitors system operation state. PCI expansion slot allows adding extra communication or I/O boards according to project requirement.
Application Scenarios Printing machinery, paper and film converting lines, metal cutting and forming equipment, packaging machines, textile machinery, automated production lines, material test equipment.
Performance Parameters Real-time kernel maintains stable control cycle for multi-axis synchronous motion. SERCOS optical bus has strong anti-electromagnetic interference capability for long distance transmission. Watchdog hardware responds immediately when system program failure appears. CompactFlash storage provides stable data storage under mechanical vibration of production site. Communication interfaces maintain continuous data exchange under complex industrial electromagnetic environment. Expansion PCI bus works stably with additional plug-in boards.
Material Composition Enclosure: Aluminum alloy metal housing with anodized anti-corrosion treatment. Main Circuit Board: FR4 multi-layer industrial PCB with conformal coating. Core Electronic Components: Embedded CPU chipset, memory chips, SERCOS optical transceiver, Ethernet controller, watchdog IC, power regulation module. Connectors: Shielded metal communication connectors, fiber optic port, power terminal block. Fasteners: Stainless steel anti-vibration screws. Internal wiring: Shielded flexible wire for internal board interconnection.
Structural Features Compact rectangular metal casing designed for cabinet installation. Front panel fitted with LED indicators for power, running and fault status. Communication ports, fiber port and USB port are arranged on front panel for convenient access. Back side equipped with DIN rail clip for fast installation inside cabinet. Internal layout separates high-speed real-time circuit, general digital circuit and power circuit to reduce crosstalk. Heat dissipation by casing heat conduction and natural air convection. PCI expansion slot reserved inside housing for optional plug-in boards.
Working Principle After 24VDC power supply is connected, internal power module supplies power to CPU, memory and peripheral interfaces. The embedded CPU boots operating system and loads Rexroth real-time motion kernel and PLC runtime. User project stored on CompactFlash is loaded into RAM for execution. Motion control software calculates axis trajectory data and transmits commands to servo drives via SERCOS optical bus. Position feedback signals return from servo system through optical bus to complete closed-loop motion calculation. Soft PLC executes logic control, safety interlock and digital signal processing. System operation data and fault events are stored locally and accessible through Ethernet or USB. Hardware watchdog continuously monitors CPU running state and triggers safety stop when system abnormality occurs.
Installation Requirements Mount unit to DIN rail or cabinet base plate inside control cabinet. Reserve air circulation space around housing to prevent heat accumulation. Connect 24VDC power wiring to the power terminal with proper wire gauge. Lay SERCOS optical fiber following specified topology, maintain minimum bending radius. Separate signal cables and high-power motor cables in different cable ducts. Check all wiring and fiber connection before power on. Download engineering project and configure axis parameters by Rexroth engineering software. Complete single axis and multi-axis motion commissioning after configuration.
Usage Precautions Do not bend optical fiber beyond minimum bending radius. Maintain cabinet internal ventilation and regular dust cleaning. Cut off power before inserting or removing CompactFlash card. Not applicable in environment with condensation, corrosive gas or heavy conductive dust. Back up user project regularly. Prohibit opening aluminum housing without professional authorization.
