ABB INNPM12

Product Description

The ABB INNPM12 is a high-performance Profibus DP Master Interface Module for ABB’s System 800xA and AC 800M controller platform, specifically designed for the S800 I/O family. This module serves as a critical gateway, enabling the powerful AC 800M controller to act as a Class 1 Master on a PROFIBUS DP (Decentralized Peripherals) fieldbus network. The primary function of the ABB INNPM12 is to facilitate deterministic, high-speed data exchange between the controller and a wide array of PROFIBUS DP slave devices, such as remote I/O stations, variable frequency drives, motor starters, and smart field instruments from various manufacturers. By integrating this widely used industrial fieldbus, the INNPM12 allows for the creation of flexible, multi-vendor automation architectures within the cohesive System 800xA environment. Its robust design ensures reliable communication in demanding process and manufacturing plants.

Advantages and Features

• Seamless System 800xA Integration: The primary advantage of the ABB INNPM12 is its native integration into the System 800xA engineering and runtime environment. Configuration, diagnostics, and asset management are unified, greatly simplifying engineering and maintenance compared to standalone gateways.
• High Performance and Determinism: As a dedicated master module, it provides deterministic and high-speed cyclic data exchange with PROFIBUS DP slaves, which is crucial for real-time control applications.
• Openness and Multi-Vendor Compatibility: Enables the AC 800M controller to communicate with thousands of PROFIBUS-compliant devices from other manufacturers, protecting investments in existing field equipment and allowing for best-in-class device selection.
• Robust and Reliable Design: Built to industrial standards with electrical isolation, the module ensures stable communication in electrically noisy environments typical of industrial plants.
• Comprehensive Diagnostics: Integrated diagnostics at the module, network, and slave device level are accessible directly from the 800xA operator workplace, enabling rapid troubleshooting and reduced downtime.

Application Cases in Key Fields

• Chemical Processing: Connects the AC 800M DCS to PROFIBUS PA instruments (via segment couplers) and DP remote I/O in hazardous areas, integrating smart temperature transmitters, level gauges, and valve positioners.
• Water and Wastewater Treatment: Acts as the master for remote I/O panels distributed across a large treatment plant, collecting data from pump stations and filter buildings and controlling motor starters for pumps and blowers.
• Manufacturing and Machine Automation: Integrates standalone machines or cells (e.g., a packaging line from a European OEM) that use PROFIBUS DP as their primary interface into a plant-wide System 800xA supervisory control system.
• Power Generation (Balance of Plant): Interfaces with motor control centers (MCCs) that feature intelligent motor starters and protection relays communicating via PROFIBUS DP, providing the central DCS with detailed motor health and status information.

Comparisons with Competing Products

• Vs. Siemens CP 443-5 Extended (for S7-400): The Siemens module offers deep integration within the TIA Portal/PCS 7 ecosystem. The ABB INNPM12 provides equivalent PROFIBUS master functionality but within the ABB System 800xA platform. The choice is dictated by the overarching DCS/PLC system brand.
• Vs. Standalone PROFIBUS DP Master Gateways: Generic gateways (e.g., from Hilscher or Anybus) can connect non-PROFIBUS controllers to a network. The INNPM12 offers superior performance, deeper diagnostics, and a more streamlined engineering experience when used with its native AC 800M controller, as it is a firmware-integrated component, not an add-on.
• Vs. Emerson DeltaV PROFIBUS DP Interface: Emerson’s solution is tailored for the DeltaV DCS. The ABB INNPM12 competes directly, with the deciding factor often being the chosen higher-level DCS platform (800xA vs. DeltaV). The ABB module is renowned for its robustness in heavy industrial settings.

Selection Suggestions and Precautions

• Selection Suggestions:
  1. Platform Commitment: This module should be selected specifically for projects based on the ABB AC 800M controller within the System 800xA DCS architecture requiring PROFIBUS DP master functionality.
  2. Network Planning: Carefully plan the PROFIBUS network topology, considering the number of slaves, cable lengths, data volumes, and required cycle time to ensure the INNPM12 can meet performance requirements.
  3. GSD File Collection: Before engineering begins, obtain the correct and latest GSD (General Station Description) files for all slave devices to be integrated.
• Precautions:
  1. Proper Network Termination: Always ensure the PROFIBUS network is correctly terminated at both physical ends with the active termination resistor switches enabled. This is the most common cause of communication faults.
  2. Grounding and Shielding: Adhere strictly to PROFIBUS cabling guidelines. Use shielded, twisted-pair cables and connect the shield to functional earth at every connecting point to prevent ground loops and ensure noise immunity.
  3. Firmware Compatibility: Verify the firmware version of the ABB INNPM12 module is compatible with the version of the System 800xA engineering and controller software being used.
  4. Configuration in Control Builder: The module and all slaves must be correctly configured in the Control Builder M hardware configuration. Incorrect settings (address, baud rate) will prevent communication.
