XYCOM XVME-202 Interface Card
XYCOM XVME-202
The XVME‑202 is a 3U high VME‑bus interface card, specifically designed to bridge the VME bus and the PAMUX distributed I/O subsystem. It connects the VME host to up to 16 PAMUX stations via a single 50‑pin ribbon cable. Each station can be configured with 32 I/O points, allowing the single card to control a maximum of 512 I/O channels.
Key Technical Specifications
| Parameter | Specification |
|---|---|
| Card Form Factor | 3U |
| Bus Type | VME‑bus (short address space: 64 KB) |
| Address Occupancy | 1 KB (base address configurable via jumpers on 1 KB boundaries) |
| I/O Channels | Up to 512 channels (16 stations × 32 points) |
| Connection Method | 50‑pin ribbon cable; maximum chain length: 500 ft (approximately 150 m) |
| Power Requirements | VME standard 5 V/±12 V power supply |
| Operating Temperature | -20 °C ~ +60 °C (industrial environment) |
Product Features
- High-Density I/O: Manages 512 distributed I/O channels with a single card, ideal for large-scale fieldbus systems.
- Modular Daisy-Chain: Connects multiple stations in series via one ribbon cable, enabling simplified wiring and reduced system costs.
- Flexible Address Configuration: Base address set via jumpers on 1 KB boundaries, ensuring compatibility with various VME hosts.
- Reliable Industrial-Grade Design: Complies with VME standard electrical specifications and features a wide operating temperature range, suitable for harsh industrial environments.
Structure and Composition
- Main PCB: Integrates VME interface, address jumper area, and ribbon cable connector.
- Ribbon Cable Interface: 50-pin circular ribbon cable socket for series connection with PAMUX stations.
- Power Distribution Module: Draws 5 V/±12 V from the VME bus to power internal logic and I/O drivers.
- Jumper Area: Used to set the card’s base address (on 1 KB boundaries).
Typical Application Fields
- Industrial Automation Control: Distributed I/O data acquisition for large production lines and robotic systems.
- Process Control: Scenarios requiring a large number of on-site sensors/actuators, such as chemical and metallurgical industries.
- Machine Tools and Numerical Control: Multi-axis coordinated motion control systems.
- Energy and Power: Power distribution monitoring and on-site bus systems in power plants.
Installation and Maintenance Guidelines
- Card Installation: Insert the XVME‑202 into a 3U slot on the VME backplane, ensuring alignment between the card’s back and the backplane socket.
- Address Jumper Setting: Configure the base address on 1 KB boundaries using the jumpers on the card’s back, following the system’s planned address space.
- Ribbon Cable Connection: Use a dedicated 50-pin ribbon cable to connect the card’s ribbon cable interface to the first PAMUX station. Connect subsequent stations in a Daisy-Chain configuration, with the total chain length not exceeding 500 ft.
- Power Check: Verify the normal operation of the 5 V/±12 V power supply provided by the VME host to avoid overvoltage or undervoltage.
- On-Site Debugging: After power-on, use the VME host’s configuration software (e.g., Indramat CLC driver) to check the I/O status of each station, ensuring all points are readable and writable.
- Maintenance: Both the ribbon cable and the card adopt a plug-and-play design for quick replacement in case of failure. Regularly inspect the ribbon cable connectors for corrosion and keep them clean.
