Bachmann PCC200 Memory Card

Hardware Specifications

Firmware Flash Compatibility & Backplane Bus Architecture

The PCC200 memory card integrates with Bachmann processing modules through a high-throughput 16-bit access bus, ensuring deterministic data transfer rates. Firmware flash compatibility mechanisms allow secure image deployment and configuration updates managed directly via the system operating software. Write protection routines are implemented at the software level to prevent unauthorized memory overwrites during runtime operations, safeguarding system integrity across industrial control networks.

Frequently Asked Questions

Q: What is the method for enabling write protection on the PCC200 card?

A: Write protection is executed via the system operating software configuration tools rather than physical hardware switches, allowing dynamic control over memory block security.

Q: Does the PCC200 support hot-swapping within the controller rack?

A: No, inserting or removing memory cards while the backplane is energized is prohibited to prevent electrical arc damage and data corruption across the 16-bit bus lines. Always power down the rack prior to hardware maintenance.

Q: What are the nominal voltage requirements for card operation and programming?

A: The card functions natively on a 5 V supply rail, while flash programming operations require a dedicated 12 V programming voltage source supplied through the backplane interface.

Field Installation Guidelines

• ESD Protection: Always wear a grounded electrostatic discharge (ESD) wrist strap when handling the memory card to protect sensitive semiconductor components from static events.
• Insertion Alignment: Align the card edge connectors precisely with the backplane slot guide rails and insert evenly without applying excessive lateral force to prevent pin distortion.
• Grounding & Shielding: Ensure the industrial control chassis maintains a low-impedance earth ground connection to mitigate electromagnetic interference (EMI) affecting the 16-bit data bus.
• Environmental Controls: Install within control cabinets meeting standard industrial operating temperature and humidity limits, avoiding direct exposure to corrosive gases or severe mechanical vibration.
