PP846A Dual-Screen Advanced Industrial HMI

Description

PP846A

The ABB PP846A functions as an advanced dual-screen hub in industrial automation architectures, building on the proven performance of the PP845 while introducing expanded visual capabilities. Positioned between control systems (PLCs, DCS) and plant operators, it enables simultaneous data visualization and control across two 12.1-inch TFT touch screens, each with 1024 x 768 resolution. This dual-display configuration allows operators to dedicate one screen to real-time process monitoring—complete with customizable dashboards, trends, and visual indicators—while using the second for active control, alarm management, or diagnostic tools.

PP846A

Like its predecessor, the ABB PP846A supports a comprehensive suite of communication protocols, including Ethernet/IP, Profinet, Modbus TCP, RS232, and RS485, ensuring seamless integration with ABB and third-party automation systems. Its enhanced processing power handles concurrent data streams from hundreds of connected devices, maintaining responsive touch interaction and instant screen updates even in data-intensive environments. The module also integrates with plant management software, enabling remote monitoring and data logging across both displays for comprehensive operational analysis.

Main features and advantages:

The ABB PP846A delivers transformative benefits to industrial operations through its dual-screen design and enhanced performance. By eliminating the need to switch between interfaces, it reduces operator cognitive load, enabling faster decision-making and minimizing the risk of oversight in complex processes. This translates directly to improved productivity—operators can monitor critical parameters on one screen while adjusting controls or addressing alarms on the other, streamlining workflows in high-pressure environments.

Engineered for durability, the ABB PP846A features an extended operating temperature range (-10°C to 55°C) and robust construction that resists vibration, dust, and moisture. This reliability ensures consistent performance in challenging settings, from cold storage facilities to hot manufacturing floors, reducing maintenance interruptions and extending service life. Its advanced connectivity simplifies integration with existing systems and future upgrades, protecting infrastructure investments while supporting scalability as operations expand.

The customizable dual displays also enhance training efficiency, allowing new operators to reference procedural guides on one screen while practicing controls on the other, accelerating proficiency and reducing onboarding time.

Application fields:

The ABB PP846A excels in industries requiring simultaneous oversight of multiple processes. In large automotive assembly plants, it monitors parallel production lines—displaying robot performance metrics on one screen while tracking quality inspection data on the other—enabling operators to address bottlenecks across the facility in real time. Its dual screens prove invaluable here, where coordinating timing between welding, painting, and assembly stations is critical to meeting production targets.

In chemical processing facilities, the ABB PP846A manages interconnected unit operations, with one screen dedicated to reactor temperature and pressure controls and the other monitoring safety systems and environmental emissions. This split-view capability ensures operators maintain regulatory compliance while optimizing production yields.

For power generation complexes, the HMI oversees turbine operations on one display and grid distribution metrics on the other, supporting efficient load balancing and rapid response to grid fluctuations. Its ATEX Zone 2 compliance also makes it suitable for hazardous areas in oil and gas refineries, where monitoring both process variables and safety interlocks simultaneously is essential.

Installation and maintenance:

Before installing the ABB PP846A, confirm your control system supports simultaneous data streaming to dual displays—check compatibility with your PLC/DCS firmware versions via ABB’s integration matrix. Ensure the mounting location provides sufficient space for the 640mm width, with at least 50mm clearance on all sides for ventilation, critical for maintaining operating temperatures in the extended range. Verify the 24V DC power supply can deliver stable 22W output to avoid performance degradation.

For maintenance, calibrate both touch screens semi-annually using ABB’s dual-display calibration tool to ensure alignment and responsiveness. Inspect inter-screen connectivity cables quarterly for wear, especially in high-vibration environments. Back up display configurations separately for each screen to facilitate quick recovery. Update firmware regularly to maintain synchronization features, and monitor internal temperature via the diagnostic menu to prevent thermal-related issues in extreme conditions.
