Product Short Description
Product Introduction
These BIMs serve as the communication backbone for GE’s PAC8000 I/O system, enabling cyclic data exchange, configuration, and diagnostics between field I/O modules and PROFIBUS-DP masters (PLCs, DCS, or SCADA systems). They operate as PROFIBUS-DP slaves, gathering real-time data from up to 24 PAC8000 I/O modules and delivering control commands to the field. Both models feature non-volatile memory for configuration retention during power cycles, HART pass-through for monitoring smart field devices, and support for redundant BIM operation when paired with 8701-CA-BI carriers to maximize system availability. The modules are configured via the PROFIBUS host or rotary switches for network addressing, ensuring quick deployment and integration into existing industrial networks. They comply with PROFIBUS-DP V1/V2 standards, guaranteeing interoperability with third-party PROFIBUS devices and controllers.

- Redundant Operation: Works with 8701-CA-BI carriers to support primary/backup BIM redundancy, eliminating single points of failure in critical systems.
- HART Pass-through: Transparent HART communication between the PROFIBUS host and HART-enabled sensors/valves, allowing remote configuration and diagnostics without additional hardware.
- Extended Diagnostics: Provides detailed status of BIM health, I/O module connectivity, and channel faults via PROFIBUS diagnostic telegrams for fast troubleshooting.
- Non-Volatile Configuration: Retains network settings, I/O mappings, and diagnostic parameters during power outages, ensuring quick system recovery.
- Flexible Addressing: Configures PROFIBUS address via front-panel rotary switches or host software for on-site or remote setup.
- 24 I/O Module Support: Scales to large systems by connecting up to 24 PAC8000 I/O modules (digital, analog, or specialty modules).
- BIM Carrier Integration: Seamlessly mounts on 8701-CA-BI carriers for power, data, and redundancy connections, reducing wiring complexity.
- PROFIBUS V1/V2 Compliance: Supports acyclic data exchange (V1) and extended diagnostics (V2) for advanced device management.
- Wide Temperature Range: Operates from -40°C to +70°C, suitable for extreme industrial environments (oil & gas, mining, power generation).
Application Scenarios
- Process Industries: Connects PAC8000 I/O modules to DCS/PLC systems in refineries, chemical plants, and pulp & paper mills, supporting HART devices for predictive maintenance.
- Power Generation: Links turbine controls, switchgear, and safety systems to PROFIBUS-DP masters in thermal, hydro, and nuclear power plants, with redundancy ensuring continuous operation.
- Oil & Gas: Integrates wellhead sensors, pipeline valves, and compressor controls in upstream/downstream operations, with HART pass-through for monitoring corrosion and flow rates.
- Water & Wastewater: Interfaces with pump stations, treatment process I/O, and SCADA systems, enabling remote monitoring of pH, flow, and pressure via PROFIBUS-DP.
- Manufacturing Automation: Connects production line sensors, motor drives, and safety interlocks to PLCs in automotive, food & beverage, and pharmaceutical facilities.
- Mining & Metals: Operates in harsh underground/mining environments, linking conveyor controls, crusher sensors, and load cells to DCS with redundant BIMs for maximum uptime.
- Building Automation: Integrates HVAC, lighting, and security systems with BMS controllers via PROFIBUS-DP, supporting large-scale commercial and industrial buildings.
Additional Information
- Configuration Software: Compatible with PROFIBUS engineering tools (e.g., Siemens Step 7, GE Proficy) for network setup, I/O mapping, and diagnostic monitoring.
- User Documentation: Refer to GE PAC8000 I/O – PROFIBUS DP BIM Instruction Manual (INM8507) for wiring diagrams, redundancy setup, and HART pass-through configuration.
