Interfaces and Configuration

Backplane interface: LCN cabinet gold fingers, dedicated graphics control bus

Peripheral interfaces: Video output (VGA), keyboard/mouse interface, parallel printing interface

Status indicators: PWR, RUN, LCN ACT, DISP, FAULT LED

Redundancy: Does not support redundancy (single card configuration for operation station)

Compatibility: Compatible with all versions of TDC 3000 LCN network, compatible with GUS/US full series of operation stations Core function

Graphics rendering processing: Receives process data from the LCN network, generates flowcharts, trend charts, alarm screens, etc. in real time, and supports dynamic refresh of complex graphic elements.

Peripheral driver control: Directly drives the operator station display, keyboard/mouse, and printer to achieve human-computer interaction command parsing and peripheral response control.

LCN data interaction: As a LCN network node, it conducts high-speed data communication with AP (application processor) and other operator stations, synchronizing process screens and system status.

Screen cache management: Uses high-speed VRAM to cache common screens, reducing LCN network transmission and improving screen switching speed and operation responsiveness.

Fault self-diagnosis: Real-time monitors graphics processing, peripheral interfaces, and LCN communication status. When a fault occurs, it lights the FAULT indicator and generates a system alarm, facilitating rapid troubleshooting. Applicable scenarios

System: Honeywell TDC 3000, TPS, Experion PKS (LCN compatible)

Equipment: Universal operation station (GUS/US), LCN network operation station cabinet, TDC 3000 process control system

Industry: Petrochemicals, thermal power, nuclear power, metallurgy, cement, pharmaceuticals, papermaking

Application: Operation station graphic display control, human-computer interaction peripheral driver, LCN network picture data processing, upgrade and replacement of old operation station display card, replacement and maintenance of faulty components
