The Yokogawa DP97*B, also cataloged as the DP97 Display Processor Card, operates as a dedicated hardware component for graphical data rendering and operator interface management within Yokogawa process control platforms.

Hardware Specifications

Process Control and Graphical Rendering

The DP97*B architecture utilizes high-speed backplane bus communication velocity to process complex human-machine interface (HMI) graphics. By offloading rendering tasks from the central controller, the module ensures deterministic update rates for operator stations. The internal circuitry provides channel-to-channel isolation from the video signal paths to prevent electromagnetic interference from distorting display outputs. The module supports seamless integration with Yokogawa's control environments, maintaining I/O density scaling through efficient data packet management across the display bus.

Frequently Asked Questions

Q: Can the DP97*B card be hot-swapped while the operator station is powered?

A: No. Hot-swapping is not supported. All power to the module must be disconnected via the system chassis before installation or removal to prevent electrical short-circuiting on the display bus.

Q: Is the display processor capable of driving multiple high-resolution monitors simultaneously?

A: The card is optimized for the resolution and refresh rates defined by the Yokogawa HMI software configuration. Exceeding specified resolution limits may cause buffer overflow and graphical stuttering.

Field Installation Guidelines

• Mechanical Installation: Slide the DP97*B into the designated display processor slot. Ensure the rear edge connector is firmly seated in the backplane socket before fastening the locking screws to provide chassis grounding.
• Grounding Protocols: Verify that the rack-mount chassis is connected to the cabinet's protective earth (PE) bus. Proper grounding is essential to stabilize the high-frequency clock signals used in video rendering.
• Cable Management: Use high-quality shielded video cabling for connections to monitors. Keep these cables separated from high-voltage AC power lines by at least 15 cm to prevent ghosting or signal interference on the display.
• Environmental Control: Maintain the ambient temperature between 0 and 50 deg C. Ensure that cooling fans within the operator station housing are functional, as the display processor generates significant heat during continuous graphical rendering operations.
