ABB TP858

Description

Product Description

The ABB TP858 is a high-performance operator terminal (panel) designed primarily for the ABB Advant OCS (Open Control System) and MOD 300 distributed control systems. This device serves as a dedicated local operator interface, providing process visualization, alarm handling, trend display, and manual control capabilities directly on the plant floor or at a local station. The ABB TP858 features a rugged, industrial-grade design with a high-resolution color display and an integrated keyboard/trackball for reliable interaction in harsh environments. It operates as a node on the MOD 300 TTP (Token-passing Terminal Bus) network, communicating directly with Advant controllers to display real-time data and execute operator commands. For facilities operating these legacy DCS systems, the ABB TP858 remains a vital tool for local monitoring and intervention. Technical specifications and manuals for this operator terminal can be found at [Insert Link Here].

Product Parameters

• Product Type: Industrial Operator Terminal / Local Operator Panel
• System Series: ABB Advant OCS, MOD 300.
• Display: Color CRT (Cathode Ray Tube) or advanced flat-panel LCD, typically with VGA resolution.
• Input Interface: Integrated industrial keyboard with function keys and a trackball or touchpad for cursor control.
• Communication Interface: Connects to the MOD 300 system via the TTP (Terminal Bus) network, typically using a coaxial cable connection.
• Processing Unit: Contains an embedded processor and dedicated memory to run the terminal’s operating system and display software.
• Functionality:
  • Process graphics display (mimics, faceplates)
  • Alarm list and acknowledgement
  • Real-time and historical trend display
  • Manual command entry (setpoints, motor start/stop)
  • Recipe management and batch supervision support
• Power Supply: Requires a dedicated AC power input (e.g., 100-240V AC).
• Enclosure: Robust metal enclosure with a NEMA 4/12 (IP65) rating for protection against dust and water, suitable for mounting in industrial control rooms or on the plant floor.

Advantages and Features

• Rugged Industrial Design: The ABB TP858 is built to withstand the temperature, humidity, vibration, and electrical noise of industrial environments, ensuring continuous operation.
• Dedicated Local Interface: Provides operators with a fast, reliable, and deterministic interface directly connected to the control network, independent of higher-level SCADA or operator stations.
• Intuitive Operation: The layout of hard function keys combined with graphical displays allows for quick navigation and execution of common commands during normal and alarm situations.
• High System Integration: As a native Advant OCS component, the ABB TP858 is fully integrated with the system’s database and engineering tools. Graphics and faceplates are configured in Advant Station and downloaded directly to the terminal.
• Reliability and Longevity: Known for its high mean time between failures (MTBF), making it a dependable asset in continuous process operations. Its design emphasizes long-term availability.
• Standalone Operation: Can function independently to provide critical operator control even if higher-level networks or central operator stations experience issues.

Application Cases in Key Fields

• Pulp & Paper Mills: Mounted locally at the wet end, press section, or dryer hood of a paper machine for operators to monitor sheet conditions, adjust speeds, and handle alarms.
• Chemical Processing: Used as a local panel for a batch reactor area, allowing operators to monitor temperature/pressure trends, execute recipe steps, and intervene manually.
• Oil & Gas (Refining): Installed near critical process units like a fluid catalytic cracking (FCC) reactor or distillation column for local parameter monitoring and valve manipulation.
• Power Generation (Fossil): Placed in the boiler or turbine control room annex for local monitoring of auxiliary systems and manual backup control.
• Metals & Mining: Used at control stations for grinding mills, flotation cells, or pelletizing plants where local operator presence is required.

Comparisons with Competing Products

In its era, the ABB TP858 competed with other DCS vendor-specific operator panels:

• Vs. Honeywell TDC 3000 GUS Consoles: The Honeywell GUS is a more advanced, UNIX-based workstation. The ABB TP858 is a more dedicated, ruggedized terminal focused on local control with simpler graphics.
• Vs. Siemens SIMATIC HMI Panels (e.g., TP27): Siemens panels are more PLC-centric and programmable with ProTool/WinCC Flexible. The ABB TP858 is deeply integrated into the Advant DCS environment with a different configuration methodology.
• Vs. Generic Industrial PCs: A generic PC running HMI software lacks the ruggedized enclosure, dedicated industrial keyboard, and deep, certified integration with the Advant control database that the ABB TP858 provides.
• Vs. Modern ABB Panels (e.g., CP600): Newer panels offer larger, brighter touchscreens, more powerful processors, and Ethernet connectivity. The ABB TP858 represents a previous generation of technology for the installed Advant base.

Selection Suggestions and Precautions

• Selection Advice:
  1. Verify System Compatibility: The ABB TP858 is exclusively for Advant OCS/MOD 300 systems with a TTP network. Ensure your system has an available TTP node address and supporting infrastructure.
  2. Define Functional Requirements: Assess the required screen size, the number of display objects, and the need for specific hard keys. Ensure the ABB TP858 model meets these needs.
  3. Plan for Environment: Its IP65 rating makes it suitable for harsh locations, but ensure ambient temperature and cleaning methods are within its specifications.
  4. Inventory Spare Parts: For critical operations, consider maintaining a spare ABB TP858 or critical sub-assemblies (like the power supply unit) due to its legacy status.
• Important Precautions:
  1. Proper Grounding and Network Termination: The TTP coaxial network must be properly terminated and grounded according to ABB specifications to prevent communication errors and protect the terminal.
  2. Handling the Display (CRT versions): Older CRT-based models are heavy and contain high-voltage components. Handle with care during installation and decommissioning.
  3. Software/Configuration Backup: The terminal’s configuration is part of the overall Advant Station project. Ensure project backups are current. The terminal itself may store local configurations that should be archived.
  4. Firmware Updates: If applicable, ensure the terminal’s firmware is compatible with the version of Advant Station and the controllers on the network.
  5. End-of-Life Considerations: As a legacy product, support and spare parts may become limited. Develop a migration or long-term support plan for critical units.
