TheABB Bailey INLIM03is a high-performance Loop Interface Module (LIM) used within theInfi 90 and Network 90 Distributed Control Systems. It serves as the primary gateway between the local module bus and the high-speed Infi-Net or Plant Loop communication rings, allowing local controllers to exchange critical process data and control commands with the rest of the network.
Specifications
Communication Speed: Operates at 10 MHz for Infi-Net or 2 MHz/500 KHz for older Plant Loop configurations.
Microprocessor: Equipped with a high-speed processor to handle complex network protocol management.
Power Requirements: Consumes approximately 11 Watts, drawing power from the +5 VDC system backplane.
Protocol Support: Compatible with both serial and peer-to-peer Infi-Net communication standards.
Data Integrity: Utilizes 16-bit Cyclic Redundancy Check (CRC) for error-free data transmission.
Memory: Contains dedicated PROM for firmware and high-speed RAM for network data buffering.
Isolation: Provides up to 1500V electrical isolation for network signal stability.
Features
Network Bridging: Acts as the essential link for transferring global data values across different system segments.
Advanced Diagnostics: Features comprehensive self-test routines that monitor both internal hardware and network health.
Traffic Management: Efficiently prioritizes real-time control data over background configuration tasks.
Failure Recovery: Supports redundant loop configurations, allowing for automatic switchover if a communication path is severed.
Front Panel Interface: Includes a multi-segment LED display to provide specific error codes and operational status in real-time.
Hot-Plug Capability: Designed for insertion into an energized Module Mounting Unit (MMU) to maintain system availability during upgrades.
