Product Short Description
Product Overview
VME industrial bus standard Profibus DP master/slave dual channel communication board, two fully independent Profibus channels with separate dedicated control DSP chips for each channel, support simultaneous operation of Profibus Class1 cyclic data exchange and Class2 acyclic parameter communication for VME rack industrial control systems.
Description
Core Technical Specifications
- VME Bus Standard: VME64 single slot 6U VME rack plug-in module
- Profibus Channel Quantity: 2 fully isolated independent DP channels
- Supported Profibus Modes: Each channel configurable as DP Master or DP Slave independently
- Profibus Baud Rate Range: 9.6kbps–12Mbps full standard baud rate support
- Data Processing Capacity: Each channel process maximum 244 bytes cyclic input/output data per Profibus cycle
- Byte Order Architecture: Intel little-endian native byte format, software configurable byte swap for Motorola big-endian VME host systems
Function Features
- Dual Channel Isolated Operation: Two Profibus networks electrically separated without signal cross-interference, realize dual redundant fieldbus communication for critical control systems
- Downloadable Independent Firmware: Each channel load separate custom Profibus firmware to connect different brand Profibus field devices simultaneously
- Comprehensive Profibus Diagnostic Function: Real-time bus signal strength, station address fault, short-circuit fault monitoring with VME host readable diagnostic registers
- Redundant Communication Compatibility: Support hot standby master redundant Profibus network architecture
Application Scenarios
Railway signal VME control systems, metallurgical rolling mill VME rack process control, nuclear power auxiliary equipment monitoring, shipboard industrial VME automation control cabinets
Installation Requirements
Plug into standard 6U VME backplane rack slot, secure front panel locking screw; use shielded Profibus DP cable for field bus wiring with bus terminator resistor installed at two cable ends
